Problems solved by technology

However, the finished products produced by these processing techniques are easily affected by external environmental factors during production, storage, transportation, and use.
Such as collisions, scratches, etc. will affect the surface appearance of the product, and the natural light, oxygen, water and some household cleaning products will cause the surface of the product to be aged and damaged during use, thus affecting the surface of the product The multi-color pattern effect reduces the service life of the product
In addition, these processing methods are complicated in technology, and secondary spraying is required to achieve the effect of marble grain or other natural grains. The production cycle is long, the scrap rate is high, the cost is difficult to control, and a large amount of organic reagents will be discharged during the production process, causing environmental pollution. pollution, affect the ecology
[0005] At present, the transparent plastics used in the market have a single color and lack aesthetics. To increase the appearance of transparent plastics, only methods such as spraying, printing, and laminating can be used, but this will affect the light transmittance and transparency of the material itself, resulting in a wide range of applications. restricted

Embodiment 1

[0053] The components and proportions of Example 1 are shown in the table below. The specific preparation process is the same as that of the comparative example, the difference is that the stirring speed is 2000 rpm, and samples are taken for observation after 3 minutes and 6 minutes of initial mixing. The final temperature of initial mixing is 65°C. The screw speed of the unit was adjusted to 200rpm.

Abstract

The invention belongs to the technical field of plastic alloy preparation, and specifically relates to an environmentally friendly plastic with controllable transparency and multi-color patterns and a preparation method thereof; it consists of 300-1000 parts of basic polymer, 100-700 parts of resin and elastomer, polymer phase 15-150 parts of compatibilizer, 2-10 parts of auxiliary agent, 5-15 parts of antioxidant, 1-5 parts of light stabilizer, 1-5 parts of color masterbatch; the characteristic formula of the present invention uses 1010, 1076, 168, With the synergistic effect of UV‑531 or DSTDP, the transparency of the plastic can be changed and a good pattern effect can be produced through the adjustment of the formula. High cost and pollution; in addition, the transparency of the environmentally friendly plastics of the present invention is controllable, and can be divided into three types: opaque, semi-transparent and transparent, which makes up for the shortage of transparent plastic products on the market and is suitable for large-scale production.

Description

technical field [0001] The invention belongs to the technical field of plastic alloy preparation, and in particular relates to an environment-friendly plastic with controllable transparency and multi-color patterns and a preparation method thereof. Background technique [0002] After the 1930s and 1940s, due to the rapid development of synthetic resins, plastics have become one of the four basic materials in the world today. At present, plastic products have been more and more used in human daily life, travel, entertainment and other industries. In today's world where material and technical conditions such as material structure and production technology meet the basic functions of use, people begin to pay more and more attention to the natural texture beauty of the material itself, such as marble grain, wood grain, cloud grain, etc., in order to satisfy people's aesthetics for products value demand. Merchants purposely carry out technical and artistic processing on the sur...
