Problems solved by technology

At present, due to the limitation of the width of the instrument itself in the manufacturing process of the conventional high-brightness flame-retardant decorative film, its maximum width can only reach 1.4m, and the specular gloss will attenuate during the production and transportation process, which is very It is difficult to ensure the durability of the specular gloss, which seriously affects the final quality of the product; in addition, although the conventional high-gloss flame-retardant decorative film has a certain flame retardancy by adding flame retardants, its mechanical properties and fluidity are limited to some extent. It affects further high-brightness processing, and black shadows will be produced in the mirror embossing process, which further affects the brightness of the product

Embodiment Construction

[0015] The present invention will be described in further detail below in conjunction with the examples, but the protection scope of the present invention is not limited thereto.

[0016] Ingredients (as shown in Table 1) → first add liquid functional additives to PVC resin powder, stir at 75°C to 80°C, then add powder functional additives, stir evenly at 95°C to 100°C, then enter banburying (temperature 165°C ℃~170℃)→2-roll rolling wheel to continue plasticizing→filtering (temperature 160℃)→four-roll calendering (185℃~190℃)→mirror embossing once (liquid silicone wheel, temperature 100℃, pressure 25Kg, speed 12m / min)→mirror non-stick lamination process (laminate the front of two decorative films, and control the peeling load at about 60cN / 5cm)→cooling→coiling→packaging. During this period, the control speed was 40 m / min.

[0017] Table 2 and Table 3 respectively list the test results of the appearance quality and internal quality of the product, indicating that the decorativ...

Abstract

The invention relates to a high brightness flame retardant decorative film, which is prepared by steps of temperature-rising agitation, banburying, filtration, four-roller rolling, primary embossing of mirror surface, non-adhesive pasting process of mirror surface, cooling, reeling and the like by taking PVC (polyvinyl chloride) resin powder and plasticizer as main materials and adding functionalassistants such as a liquid flame retardant, an EVA (ethylene vinyl acetate)-grafted copolymer, soybean oil, a stabilizer and the like. The high brightness flame retardant decorative film of the inveiton has excellent properties such as durable mirror-surface luster, efficient flame retardancy, good strength, size stability and the like.

Description

technical field [0001] The invention belongs to the field of PVC film functional materials, and in particular relates to a high-brightness flame-retardant decorative film, which can be used in industries such as construction and home appliances. 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 artific...
