Problems solved by technology

[0002] The existing plastic sheets used for the production of blister products, packaging printed matter, etc. generally have the following deficiencies: 1. The sheet (conventional plastic sheet) does not degrade, pollutes the environment, and is not environmentally friendly; 2. The sheet can be degraded, but its When processing, some starch is added, resulting in dull, uneven color, bad hand feeling and complicated processing
3. The sheet can be degraded, has good color and feel, but the cost is high

Embodiment Construction

[0011] The present invention will be further described below in conjunction with embodiment.

[0012] A thermo-oxygen degradable polypropylene sheet, including a sheet processed by extrusion from a mixed material, the mixed material mainly consisting of 95%-98% polypropylene raw material, 1%-2% thermo-oxygen degradation aid and 1%-3% dispersant is stirred and mixed at a high speed under the working condition of 50°C-60°C.

[0013] The mixed material is extruded into a sheet through a sheet extruder under the working condition of 180°C-230°C.

[0014] The thermal oxygen degradation aid is d2w thermal oxygen degradation aid; the dispersant is ethylene bis stearamide.

[0015] As an embodiment, the mixed material mainly includes 95% polypropylene raw material, 2% thermo-oxidative degradation aid and 3% dispersant.

[0016] As another embodiment, the mixed material mainly includes 98% polypropylene raw material, 1% thermo-oxidative degradation aid and 1% dispersant.

Abstract

A thermal oxidative degradation polypropylene sheet comprises a sheet formed through extruding a mixed material, and the mixed material is obtained through the high-speed stirring and mixing of 95-98% of a polypropylene raw material, 1-2% of a thermal oxidative degradation assistant and 1-3% of a dispersant at 50-60DEG C. The sheet is formed through extruding the mixed material at 180-230DEG C by a sheet extruder. The thermal oxidative degradation polypropylene sheet has the advantages of simple processing technology, degradation, low cost, good color and hand feeling, excellent quality and reasonable price, environmental protection and energy saving.

Description

technical field [0001] The invention relates to a thermo-oxygen degradable polypropylene sheet used for producing blister products, packaging printed matter and the like. Background technique [0002] The existing plastic sheets used for the production of blister products, packaging printed matter, etc. generally have the following deficiencies: 1. The sheet (conventional plastic sheet) does not degrade, pollutes the environment, and is not environmentally friendly; 2. The sheet can be degraded, but its During processing, some starch is added, resulting in dull, uneven color, bad hand feeling, and complicated processing. 3. The sheet material can be degraded, has good color and luster, and feels good, but the cost is high. Contents of the invention [0003] The purpose of the present invention is to provide a thermal oxygen degradable polypropylene (PP) sheet material with simple processing technology, degradable, low cost, good color and feel, low price, environmental pr...
