Abstract

The invention discloses a BOPET protection film for a heat and fire resistant plate. The protection film treats a BOPET film as a base film, and a heat resistant organosiloxane coat having a thickness of 2-5mum is on the surface of the base film. The heat resistant organosiloxane coat is obtained through a step of carrying out corona treatment of the surface of the BOPET film to realize the corona value of 48-52 dynes, a step of coating an organosiloxane coating onto the surface of the BOPET film through a coater, and a step of thermocuring, wherein the organosiloxane coating comprises 1-90 parts by weight of a diluent, 4-50 parts by weight of a prepolymer, 0-10 parts by weight of an inorganic additive, 2-15 parts by weight of hydrochloric acid and 50-85 parts by weight of water, and the prepolymer is at least one of alkoxysilane, glycidyl ether and metal alkoxide. The coat has a good firm uniformity with the base film, and the heat and fire resistances of the film are improved, so the BOPET protection film can be used as the fire resistant plate protection films of household building materials and electrician circuits.

Description

technical field [0001] The invention belongs to the field of thin films, and in particular relates to a BOPET protective film for a heat-resistant fireproof board. Background technique [0002] BOPET film (that is, biaxially oriented polyester film) has the characteristics of high strength, good rigidity, transparency, and high gloss; especially odorless, tasteless, colorless, non-toxic, and outstanding strength and toughness, and is widely used in automobiles. , Home furnishing, and the protective film of electronic products. However, in practical applications, it is found that the ordinary BOPET film is not good in heat shrinkage, flame retardancy and fire prevention. Contents of the invention [0003] The invention aims at improving the heat resistance of the BOPET film, and provides a BOPET protective film for a heat-resistant fireproof board. [0004] The technical scheme adopted by the present invention to realize the above object is as follows: [0005] The inve...
