PP plastic antifogging sheet and preparation process thereof

Abstract

The invention belongs to the technical field of PP plastic antifogging, and particularly relates to a PP plastic antifogging sheet and a preparation process thereof.The PP plastic antifogging sheet comprises an antifogging sheet body and an antifogging coating coated on the surface of the antifogging sheet body, and the extrusion formula of the antifogging sheet comprises, by weight, 0.5 part of PP-450E raw material, 0.5 part of PP-5015 recycled material, 0.5 part of polypropylene, 0.5 part of polypropylene, 0.5 part of polypropylene and 0.5 part of polypropylene. The antifogging coating formula of the antifogging coating coated on the surface of the antifogging sheet comprises the following components in parts by weight: 1.5 parts of antifogging agent, 3 parts of water and 3 parts of alcohol. The production of the PP anti-fog extrusion sheet does not need anti-fog master batches, so that the production cost is reduced; the PP-450E raw material and the PP-5015 recycled material can promote each other, so that the forming effect and the anti-fog effect of the sheet are improved; through a coating processing mode, the coating anti-fog liquid is uniformly transferred to the surface of a pp sheet. The pp sheet coated with the anti-fogging liquid is baked through a baking oven, redundant alcohol and water are volatilized and dried, the anti-fogging liquid is solidified on the surface of the pp sheet, and the anti-fogging effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of PP plastic anti-fog, and in particular relates to a PP plastic anti-fog sheet and a preparation process thereof. Background technique [0002] At present, PP anti-fog extrusion sheets on the market are mostly produced by adding anti-fog masterbatches to PP anti-fog extrusion sheets, but the production cost of PP anti-fog sheets after adding anti-fog masterbatches is high and the anti-fog effect is high. Not good, its anti-fog effect can only reach the 3-level anti-fog of the national standard (GB / T31726-2015) detection method, and cannot reach the 1-level anti-fog in the national standard. [0003] The technical problems to be solved by the present invention are: the PP anti-fog extruded sheet on the market has high cost, poor anti-fog effect, and cannot reach the technical problems of the first-level anti-fog in the national standard. SUMMARY OF THE INVENTION [0004] In order to overcome the deficien...

AI Technical Summary

Problems solved by technology

[0002] At present, PP anti-fog extruded sheets on the market are mostly produced by adding anti-fog masterbatches to PP anti-fog extruded sheets, but the production cost of PP anti-fog sheets after adding anti-fog masterbatches is relatively high and the anti-fog effect is low. Poor, its anti-fog effect can only reach level 3 anti-fog of the national stand
