Problems solved by technology

[0003] For example, the Chinese patent application publication number "CN107266840A" discloses a method for preparing flame-retardant and heat-insulating acrylic sheets. Formyl, wood powder, colorant, simethicone, etc. make the prepared acrylic protective film have certain heat insulation and flame retardant effects, but because these external additives are only added into the acrylic production process by physical mixing, It is not possible to change the properties of the raw material of the acrylic sheet

Abstract

The invention relates to a thermal-insulation acrylic protective film. The thermal-insulation acrylic protective film is mainly prepared from acrylic master batch and an external additive, wherein a preparation method for the external additive comprises the following steps that 1, a solvent is prepared, specifically, Arabic gum, a surfactant and a coalescing agent are dissolved in an organic solvent, and uniform stirring is carried out; 2, a fireproof flame retardant is prepared; 3, the fireproof flame retardant prepared in the step 2 is added into the solvent prepared in the step 2, and stirring is carried out at a high speed; 4, heating is carried out so as to remove the organic solvent; 5, nanometer silica gel and absolute ethyl alcohol are mixed so as to form an auxiliary agent A; 6, carboxy methyl cellulose, polyvinyl alcohol and polyoxyethylene are mixed and dissolve so as to form an auxiliary agent B; and 7, the auxiliary agent A and the auxiliary agents B are sequentially compounded outside an oil-in-water form treated in the step 3, radiation treatment is carried out, the radiation dose is 30-60 KGy, and the radiation time is 40-100 hours, and therefore polymer gel is formed. The prepared thermal-insulation acrylic protective film has a good thermal insulation effect.

Description

technical field [0001] The invention relates to an acrylic protective film, in particular to a heat-insulating acrylic protective film. Background technique [0002] Acrylic board has good weather resistance and acid and alkali resistance, and will not cause yellowing and hydrolysis due to years of sun and rain. It has a long lifespan. Compared with other materials, the lifespan is more than three years longer. It is used outdoors , the crown of other plastics, it is characterized by excellent transparency, colorless transparent organic glass sheet, light transmittance of 92%, with excellent weather resistance, strong adaptability to the natural environment, even if it is exposed to sunlight and wind for a long time Even if it is exposed to rain, it will not change its performance, and it has good anti-aging performance, so it can be used outdoors with peace of mind. Good processing performance, suitable for both machining and thermoforming. Excellent comprehensive perform...
