A kind of impact-resistant high-efficiency flame-retardant decorative film and its preparation method

Abstract

The invention relates to an impact-resistant and high-efficiency flame-retardant decorative film and a preparation method thereof. The decorative film is prepared from the following raw materials in parts by weight: 80-120 parts of PVC resin powder, 30-50 parts of plasticizer, and 0.5-5 parts of soybean oil , 18-45 parts of composite flame retardant, 0.5-5 parts of formaldehyde absorbent, 0.5-5 parts of environmental stabilizer, 0.5-5 parts of smoke suppressant, and 5-15 parts of nano-calcium powder. Using PVC resin powder as the main raw material, adding plasticizers, composite flame retardants, soybean oil, formaldehyde absorbents, stabilizers, smoke suppressants, and nano-calcium powders as functional additives, through high-speed stirring and mixing, molding extrusion, The decorative film is produced by first rolling machine plasticizing, second rolling machine plasticizing, filtering, calendering, cooling, and coiling. The present invention optimizes the production process parameters by optimizing the formula, and the prepared decorative film has the characteristics of excellent flexibility, high-efficiency flame retardancy, environmental protection, high compliance, good impact resistance, etc., and also has the effect of purifying formaldehyde , has a good market prospect.

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...
