Environment-friendly flame-retardant plastic plate for building

Abstract

The invention mainly relates to the technical field of plastic plate processing, and discloses an environment-friendly flame-retardant plastic plate for a building. The environment-friendly flame-retardant plastic plate for the building is prepared from the following raw materials: phenolic resin, polyurethane resin, polytetrafluoroethylene, modified epoxy resin, polymethyl methacrylate, amino silicon oil, glass fibres, nano-zinc oxide, nano-silver and graphene; the environment-friendly flame-retardant plastic plate for the building provided by the invention is high in strength, strong in durability, free from formaldehyde release, green and healthy; the flame retarding level reaches V-0 level; the personal and property safety is guaranteed effectively; the types of plates on the market are increased; the requirements of customers are met; the phenolic resin, the polyurethane resin, the polytetrafluoroethylene and the modified epoxy resin are fully molten, so that the raw materials arefully grafted; therefore, the strength and the aging resistance of the plastic plate are improved; the aging phenomena, such as fracture and discoloration, of the plastic plate in a using process aredelayed; higher use and decoration performance is maintained.

Description

technical field [0001] The invention mainly relates to the technical field of plastic plate processing, in particular to an environment-friendly flame-retardant plastic plate for construction. Background technique [0002] Plastic sheets are made of polymer compounds, which are highly practical and widely used in the construction, chemical and automotive industries. Formaldehyde is highly volatile in plastic sheets, which is very harmful to the human body and the environment, and the plastic sheets currently available on the market have poor heat resistance and flame retardancy, and are easy to burn when exposed to open flames, causing great hidden dangers to personal and property safety. [0003] The existing patent document CN 105440682 A discloses an environmentally friendly plastic board, which can improve the aging resistance of the plastic board to a certain extent, but the strength of the plastic board obtained in the patent document is low and cannot meet the needs o...

Problems solved by technology

[0002] Plastic sheets are made of polymer compounds, which are highly practical and widely used in the construction, chemical and automotive industries. The high volatility of formaldehyde in the plastic sheet has great harm to the human body and the environment, and the currently commercially available plastic sheet has poor heat resistance and flame retardancy, and is easy to burn when exposed to an open flame, causing great hidden dangers to personal and property safety.

[0003] The existing patent document CN 105440682 A discloses an environmentally friendly plastic board, which can improve the aging resistance of the plastic board to a certain extent, but the strength of the plastic board obtained in the patent document is low and cannot meet the needs of construction; the existing patent document CN 103897421 A discloses a flame-retardant plastic board, which makes the obtained plastic board have good flame retardancy. However, although the flame retardant added to the plastic board can play a flame-retardant role after encountering an open flame, it will release Toxic gas will also endanger life safety, and the strength of the obtained plastic board cannot meet the needs of building boards
