preparation example Construction

[0049] The preparation method of the environmentally friendly composite material made of waste plastics comprises the following steps:

[0050] S1: Wash and dry the waste plastics until the water content is ≤0.8%, then mix and pulverize the dried plastics and EPDM grafted with maleic anhydride, and pass through a 200-300 mesh sieve to obtain plastic powder;

[0051] S2: adding a surfactant to the plastic powder prepared in step S1, and activating it for 1.2-1.8 hours at a temperature of 70-74° C. and a rotation speed of 150-180 r / min to obtain an activated plastic powder;

[0052] S3: Under nitrogen protection, add polylactic acid, sodium tripolyphosphate, 2-hydroxy-4-octyloxybenzobutanone, butenyl bisstearamide, ethylene glycol to the activated plastic powder prepared in step S2 Alcohol monostearate, tributoxyethyl phosphate, tris(2,4-di-tert-butylphenyl) phosphite, regulator, generating agent, crosslinking agent, compatibilizer, bridging agent, Catalyst, plasticizer, dispersa...

Abstract

The invention discloses an environment-friendly compound material prepared from waste plastics and application thereof. The environment-friendly compound material prepared from the waste plastics comprises the following raw materials: waste plastics, maleic anhydride grafted ethylene propylene terpolymer, polylactic acid, sodium tripolyphosphate, 2-hydroxy-4-zinc-oxo-diphenyl butanone, butenyl stearamide, glycol monostearate, phosphoric tri-butoxy ethyl ester, tri(2,4-tertiary butyl phenyl) phosphite ester, a surface active agent, a modifier, a generating agent, a cross-linking agent, a compatilizer, a bridging agent, a catalyst, a plasticizer, a dispersing agent, a tackifier, a curing agent, an antioxidant, a stabilizer, an anti-aging agent, a fire retardant and a smoke suppressor. The environment-friendly compound material prepared from the waste plastics is prepared according to the steps of cleaning, drying, crushing, activating, mixing, extruding and the like. The abrasive resistance and the tensile strength of the environment-friendly compound material prepared from the waste plastics provided by the invention are obviously better than those of a plastic material in the prior art.

Description

[0001] 【Technical field】 [0002] The invention belongs to the technical field of material preparation for 3D printing, and in particular relates to an environmentally friendly composite material made of waste plastics and its application. [0003] 【Background technique】 [0004] 3D printing, also known as rapid prototyping technology, is also called additive manufacturing technology. It does not require traditional tools, fixtures and machine tools, but is based on digital model files, using adhesive materials such as metal powder or plastic Layer printing technology to manufacture objects of any shape. 3D printers can manufacture many items, such as airplanes, pistols, food, human organs, children's toys, etc. 3D printing technology is a major breakthrough in the world's manufacturing technology field in the past 20 years. It is the integration of multidisciplinary technologies such as mechanical engineering, computer technology, numerical control technology, and material s...
