Problems solved by technology

However, in the existing process, the stamping and coating of the aluminum plate are carried out simultaneously. When stamping and coating the wire-drawn aluminum plate, problems such as residual glue, sticking, indentation, scratches and pollution are prone to occur. Moreover, the existing Films with known formulations have defects in processing toughness and weather resistance

Embodiment Construction

[0023] The present invention will be further described in detail below with reference to the embodiments, so that those skilled in the art can implement according to the description.

[0024] This case proposes an embodiment of a special protective film formulation for a brushed aluminum plate, which includes the following materials in parts by weight:

[0025]

[0026] Among them, the density of low density polyethylene is 0.898~0.918g / cm 3 , the density of linear low density polyethylene is 0.920~0.932g / cm 3 . In this case, linear low density polyethylene (LLDPE) is not only different from low density polyethylene (LDPE) in terms of density and molecular weight, but also has obvious differences in structure. LLDPE does not have long chain branches in its structure. Although low-density polyethylene may not have long-chain branches in theory, in reality, low-density polyethylene contains a certain amount of long-chain branches. Therefore, in this case, low-density polyet...

Abstract

The invention discloses a formula for a special protective film of a brushed aluminum plate. The formula comprises the following materials in parts by weight: 50-60 parts of low-density polyethylene, 20-30 parts of linear low-density polyethylene, 5-10 parts of SEBS, 0.1-0.3 part of an antioxidant, 0.2-0.3 part of polyethylene wax, and 0.1-0.2 part of oleamide. Through the adoption of the elasticity and self adhesive force of SEBS, the problem of glue residues on a glue coating film is effectively solved, and the problems of indentation, scratch, pollution and the like appearing in a stamping process of the brushed aluminum plate are solved; through the addition of the polyethylene wax, the protective film can be quicker and more convenient to form and easy to peel off, so that the sticky phenomenon after stamping of the brushed aluminum sheet is prevented, that is, not only can the stickiness be kept, but also the protective film can be conveniently tore down; through the introduction of a composite antioxidant in the formula, the ageing-resistant performance of the protective film is greatly improved, and the weathering-resistant performance of the brushed aluminum plate is improved. Therefore, the protective film is more durable.

Description

technical field [0001] The invention relates to a formula of a polymer film, in particular to a formula of a special protective film for a wire drawing aluminum plate. Background technique [0002] The special protective film for brushed aluminum plate is a special polymer film used to protect the brushed aluminum plate and cover the surface of the brushed aluminum plate. This kind of film requires stable viscosity, convenient use, easy tearing and sticking, no glue residue, high elongation, strong fracture resistance, good packaging performance, moisture-proof and rain-proof. However, in the existing process, the stamping and coating of the aluminum plate are carried out simultaneously. When stamping and coating the brushed aluminum plate, problems such as residual glue, sticking, indentation, scratching and pollution are prone to occur. Films of known formulations are deficient in processing toughness and weatherability. SUMMARY OF THE INVENTION [0003] In view of the...
