Abstract

The invention relates to an anti-shock efficient flame-retardant decorative film and a preparation method thereof. The decorative film is prepared from, by weight, 80-120 parts of PVC resin powder, 30-50 parts of a plasticizer, 0.5-5 parts of soybean oil, 18-45 parts of a composite flame retardant, 0.5-5 parts of a formaldehyde absorbent, 0.5-5 parts of a environment-friendly stabilizer, 0.5-5 parts of a smoke suppressant and 5-15 parts of nano-calcium powder. The PVC resin powder is adopted as the main raw material, and the plasticizer, the composite flame retardant, the soybean oil, the formaldehyde absorbent, the stabilizer, the smoke suppressant and the nano-calcium powder are added as functional auxiliaries. The decorative film is obtained through high-speed stirring and mixing, forming extrusion, first rolling mill plastification, second rolling mill plastification, filtration, calendaring, cooling and reeling. Accordingly, by means of the optimized formula, production process parameters are optimized, the prepared decorative film has the advantages of being excellent in flexibility, efficient flame resistance and environmental friendliness, high in compliance, good in shockresistance and the like, and meanwhile the effect of purifying formaldehyde is achieved; the film has good market prospects.

Description

technical field

[0001] The invention relates to the technical field of decorative films, in particular to an impact-resistant high-efficiency flame-retardant decorative film and a preparation method thereof. Background technique

[0002] The thin film used as a decoration is one of the earliest developed films in my country, the most extensively involved, the most participating research units, and the most significant economic benefits in mass production. At present, with the rapid development of industries such as construction, transportation, and home appliances, and the gradual improvement of people's aesthetic requirements, decorative films that play a role in decorative protection have been used more and more widely, especially PVC decorative films. Due to its unique advantages, PVC decorative film has been widely studied and used. It can obtain higher hardness on the surface of the decorated object, prevent the surface from artificial scratches, abrasions or bumps, and...
