Problems solved by technology

[0004] The existing turnover boxes and other items made of plastic raw materials are used for the packaging of some medicines, electronic instruments and other items, which require good transparency and clarity. However, the transparency of containers such as turnover boxes made of existing plastic raw materials Poor clarity, making it impossible to see the contents of the container
Secondly, the existing plastic raw materials are still not easy to demould, which leads to problems such as glueing or scratches between the container and the mold when demoulding, which in turn affects its transparency and clarity
Furthermore, these turnover box containers need to be used for the transportation of goods, so their toughness needs to be better, and some containers made of plastic materials have poor toughness, which makes the containers easy to break and be damaged, and their service life is short

Embodiment 1

[0015] Embodiment 1: A plastic raw material, comprising: 70 parts of PP, 21 parts of PE, 7.5 parts of POE, 0.5 parts of composite light diffusing agent and 1 part of auxiliary agent in parts by weight. PP has high impact resistance, strong mechanical properties, and resistance to various organic solvents and acid-base corrosion; its molar mass is relatively large, and the MFR is less than 0.5g / 10min; there are many ligature molecules, and the ability to prevent cracks from expanding is strong; The molar mass distribution is wide and bimodal, which is convenient for processing and production; it is copolymerized with ethylene or other α-olefins to provide better impact resistance. PE has excellent environmental stress cracking resistance and electrical insulation, high heat resistance, impact resistance and puncture resistance, etc. POE has both excellent toughness and good processability; there is no unsaturated double bond in the molecular structure of POE plastics, which has...

Embodiment 2

[0023] Embodiment 2: A plastic raw material, the difference from Embodiment 1 is that it includes: 70 parts of PP, 21 parts of PE, 4 parts of POE, 2 parts of composite light diffusing agent and 3 parts of additives in parts by weight.

Embodiment 3

[0024] Embodiment 3: A plastic raw material, which differs from Embodiment 1 in that it includes, in parts by weight: 80 parts of PP, 15 parts of PE, 2 parts of POE, 1 part of composite light diffusing agent and 2 parts of additives.

Abstract

The invention discloses a plastic raw material. The technical scheme is as follows: the plastic raw material comprises the following components in parts by weight: 70-80 parts of PP (polypropylene), 15-21 parts of PE (polyethylene), 2-8 parts of POE (polyolefin elastomer), 0.5-2 parts of composite photodiffusion agent and 1-3 parts of assistant. The plastic raw material disclosed by the invention solves the problems of low transparency, difficulty in demolding and poor toughness in the container prepared from the existing plastic raw material.

Description

technical field [0001] The invention relates to a raw material formula, more specifically, it relates to a plastic raw material. Background technique [0002] Plastic parts are widely used in every field of modern life, such as household appliances, instruments, wires and cables, construction equipment, communication electronics, automobile industry, aerospace, daily hardware, transportation containers, etc. Some of the things used here, such as turnover boxes, trays, and housings of household appliances, are all made of plastic materials. [0003] Plastic raw material: It is made of polymer synthetic resin (polymer) as the main component, infiltrated with various auxiliary materials or additives, and has plasticity and fluidity under specific temperature and pressure, and can be molded into a certain shape, and under certain conditions A material that retains its shape. [0004] The existing turnover boxes and other items made of plastic raw materials are used for the pac...
