Nowadays, synthetic resin tiles have become widely used building materials in construction, and are used in development areas such as flat slopes, farmer's markets, residential quarters, new rural construction residential villas, awnings, awnings, and antique buildings. Next, Xiaobian introduces the history of synthetic resin tiles.
In 1872, when phenol and formaldehyde were heated under acidic conditions, they quickly formed reddish-brown lumps or viscous materials, which were discovered by the chemist Bayer, but they were stopped because they could not be purified by the old method. After the 20th century, phenol and formaldehyde were available in large quantities, which made the reaction products of both of them more interesting. People hope to develop useful products, but many people are difficult to succeed. In 1904, Baekeland and his assistants also carried out the study, hoping to make insulating varnish instead of natural resin. Later, they not only produced insulating varnishes, but also made true synthetic plastic materials. However, after entering the 20th century, natural products have been unable to meet the needs of electrification
