EPS foam wrapping plate and production technology thereof

Abstract

The invention discloses an EPS foam wrapping plate, and relates to the technical field of EPS. The EPS foam wrapping plate is produced from, by mass, 100-200 parts of styrene resin, 2-6 parts of a foaming agent, 50-90 parts of bamboo charcoal fibers, 2-4 parts of polycarbonate, 1-2 parts of aluminum hydroxide, 1-2 parts of magnesium hydroxide, 1-5 parts of a curing agent, 1-2 parts of a coupling agent, 1-2 parts of a lubricant, 1-2 parts of a brightening agent, 1-4 parts of a compatilizer, 2-4 parts of a dispersant, 0.1-0.3 part of nitrogen, 2-4 parts of a softener and 2-4 parts of a grain-refining agent. The ignition point of the EPS foam wrapping plate is improved, so the damages of articles in fire are maximally reduced; and the bamboo charcoal fibers are added, and the bamboo charcoalfibers have a good antibacterial effect, so the purpose of preventing the articles from being polluted with bacteria in the wrapping and transporting process is achieved.

Description

technical field [0001] The invention relates to the technical field of EPS, in particular to an EPS foam packaging board and a preparation process thereof. Background technique [0002] Polystyrene foam is a light polymer. It uses polystyrene resin to add foaming agent, while heating to soften, generate gas, and form a foam plastic with a rigid closed-cell structure. [0003] Its processing method can be divided into pattern method and extrusion method according to the different foaming methods. This uniform and closed cavity structure makes EPS have the characteristics of low water absorption, good heat preservation, light weight and high mechanical strength. Northern Europe began to use EPS for civil engineering in the late 1960s. In 1971, the Norwegian National Road Research Laboratory for the first time used EPS to replace the 1m thick ordinary filler in the FLOM bridge approach renovation project, successfully controlling the uneven settlement of the bridgehead secti...

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides an EPS foam packaging board and its preparation process, which solves the problem that the current EPS foam packaging board is easy to burn when encountering an open flame, has poor safety performance, and has poor fire insulation performance for article packaging. As a result, the packaging quality of the article is poor, and the processing operation of the existing EPS foam packaging board is complicated, and the quality of the EPS foam packaging board produced and processed is poor.
