Abstract

The invention discloses a composite plastic with good acid and alkali resistance and a preparation method thereof. The composite plastic contains the following raw materials in parts by weight: 21-27parts of PVC (Poly Vinyl Chloride) resin, 8.6-12.5 parts of polyethylene oxide, 32-45 parts of polyolefin elasticity, 0.8-1.6 parts of coupling agent, 6-10 parts of methyl ethyl ketone peroxide, 1-2 parts of antioxidant, 12-16.4 parts of nanometer zirconium dioxide, 10-15 parts of grapefruit skin, 3.6-5.5 parts of glass fiber and 8-12 parts of styrene-acrylic emulsion. The composite plastic disclosed by the invention has the advantages that different products are obtained by adopting different preparation processes through the different raw materials and mixed to obtain a finished product which has no change in a citric acid solution with a mass fraction of 6% for 120 hours or a sodium hydroxide solution with a mass fraction of 22% for 150 hours; and the composite plastic has good acid resistance and alkali resistance.

Description

technical field [0001] The invention relates to the field of plastics, in particular to a composite plastic with good acid and alkali resistance. Background technique [0002] Plastics are polymer compounds that are polymerized from monomers through addition polymerization or polycondensation reactions. The composition and shape can be changed freely. It is composed of synthetic resins and fillers, plasticizers, stabilizers, lubricants, colorants and other additives. composition. Plastic has become a commonly used material in people's life and work, and is widely used in automobiles, packaging, chemicals, petroleum and other fields. [0003] Most of the existing plastic products are copolymers. When encountering acidic or alkaline substances, plastics will corrode. This phenomenon is especially common in the production of chemicals, which affects the personal safety of production personnel and production. Workshop production safety. People are also studying the acid and a...
