Introduction to the History of Synthetic Resin Tile Materials and Synthetic Resin

2023-11-07

In 1872, when phenol and formaldehyde were heated under acidic conditions, they could quickly form a reddish brown hard lump or viscous substance, which was discovered by chemist Bayer. However, the experiment was stopped because they could not be purified using the old method. After the 20th century, phenol and formaldehyde were widely available, which made the reaction products of the two more attractive. People hoped to develop useful products, but many people found it difficult to succeed. In 1904, Beckland and his assistants also conducted this study with the aim of producing insulating paint that could replace natural resins. Later, they not only produced insulating paint, but also made truly synthetic plastic materials. However, after entering the 20th century, natural products were no longer able to meet the needs of electrification, prompting people to search for new cheap substitutes. Synthetic resin is the main component of synthetic resin tiles, with a high content. This often determines the properties of synthetic resin tiles based on the properties of the resin. Phenolic resin, which uses coal tar as the raw material, has been the largest producer of various synthetic resins until 1940, reaching over 200000 tons per year. However, with the development of petrochemical industry, the production of polymerized synthetic resins has continued to expand, and they have become the four types of synthetic resins with higher production today. Synthetic resin tiles, combined with additives, are obtained through various molding methods and have become the basic materials for production, daily life, and national defense construction.

Nowadays, synthetic resin tiles have become widely used building materials in construction, and are used in development zones to upgrade slopes, agricultural markets, residential communities, new rural construction of residential villas, awnings, sunshades, antique buildings, etc. Next, the editor will introduce the history of synthetic resin tiles to you.

C9 Petroleum Resin Usage

Petroleum resin is different from general resins and cannot be used alone. It is usually blended with other substances to improve the performance of various products. Petroleum resins are mainly used in the following areas: (1) Application in the paint industry. In the coating industry, petroleum resin can be combined with other resins to completely or partially replace high-value resins, thereby achieving the goal of reducing costs, improving the luster, hardness, water resistance, stability, and chemical resistance of products. If C9 petroleum resin is used in the formulation of phenolic varnish to replace rosin modified phenolic resin and rosin calcium resin in equal quantities, the resulting product still meets the standards of phenolic varnish and phenolic enamel. However, the cost of C9 petroleum resin is less than 1/4 of that of rosin modified phenolic resin, which can greatly reduce costs. Adding alicyclic petroleum resin to epoxy resin and polyurethane blended paint can improve the hardness, bending test, temperature water resistance, weather resistance, and other indicators of the product. (2) Application in adhesives. In adhesives, petroleum resin mainly plays a role in providing adhesion. The main components of adhesive are basic polymers such as natural rubber, synthetic rubber, polyolefin, polyacrylic acid vinegar, ethylene vinyl acetate copolymer, etc. The addition of petroleum resin can improve the bonding stability, creep resistance, heat resistance, and other properties of these polymers. If petroleum resin and SBS thermoplastic elastomer block copolymer are mixed in a mixed solvent of toluene hexane, the resulting viscous mixture can be used to prepare pressure sensitive adhesive tapes as pressure sensitive adhesives. (3) Application in the rubber industry. C9 petroleum resin is mainly used as a softening additive in the rubber industry. The styrene butadiene rubber itself lacks viscosity and is hard. Adding C9 petroleum resin causes the molecular chains of styrene butadiene rubber to be divided, resulting in a good viscosity and softness of the product. On the other hand, C9 petroleum resin can reduce the amount of natural rubber to synthetic rubber, significantly reducing costs without changing the quality of rubber products. In terms of technology, the use of petroleum resin can save a raw rubber refining process, shorten the production cycle, and improve economic benefits. (4) Application in printing ink. In ink, petroleum resin is mainly used as a connecting material. Petroleum resin has good compatibility with many components in ink, and for various specifications of printing ink, there are corresponding petroleum resins to meet the requirements of various indicators such as wetting speed, drying speed, solvent release, water and alkali resistance. Petroleum resin is processed into ink, which can maintain a stable dispersion state of pigments for a long time

Why can synthetic resin tiles replace traditional tiles?

Synthetic resin tile products have the characteristics of bright and rich colors, so construction companies can better leverage their design advantages to make the building more aesthetically pleasing. At the same time, synthetic resin tiles can also effectively prevent fire, insulation, and pollution, and have a strong three-dimensional sense after construction, so they are now widely used in various buildings. So why can synthetic resin tiles replace traditional tiles? 1. Color options are bright and long-lasting: Traditional cement tiles or clay tiles have a very single color, while glazed tiles have fewer colors to choose from although they are more vibrant. The formula carefully developed by synthetic resin tile manufacturers can give synthetic resin tile products a rich and colorful color range. At the same time, when applied outdoors, they can withstand ultraviolet radiation and are not afraid of cold and hot environments. They can still maintain color stability in unfavorable outdoor environments, so they will not fade and ensure long-lasting bright colors. Therefore, it can effectively replace traditional tiles in decorating buildings. 2. Impact resistance is not easy to break: Synthetic resin tiles have excellent impact resistance due to their main use of synthetic resin. Therefore, when used on the top floor of a building, they will not easily break and cause danger when encountering unexpected falls and collisions. However, traditional tiles, whether they are cement tiles, clay tiles, or glazed tiles, are very easy to break, so they will gradually be replaced by new synthetic resin tile products. 3. Good insulation and cold insulation: Due to the low thermal conductivity of synthetic resin tiles, they can provide good insulation and reduce energy consumption for building users to a certain extent. According to tests, the thermal conductivity of ordinary tiles is higher than that of synthetic resin tiles, so from the perspective of insulation, the products produced by synthetic resin tile manufacturers can effectively replace traditional tiles. The above three aspects are the main reasons why synthetic resin tiles can replace traditional tiles. In addition, the synthetic resin tiles produced by reliable synthetic resin tile manufacturers also have good waterproof properties, which can effectively protect the building from rainwater erosion, thereby improving the performance of the building and preventing users from leakage.
