PET (polyethylene terephthalate)/montmorillonite nano composite special for engineering plastic and manufacture method hereof

Abstract

The invention discloses PET (polyethylene terephthalate) / montmorillonite nano composite special for engineering plastic, manufactured from, by weight, 58-60 parts of PET resin, 20-22 parts of polyvinylidene fluoride, 5-7 parts of montmorillonite, 1.4-1.8 parts of nano alumina, 6-8 parts of carbon fiber, 0.7-0.9 part of zinc powder, 0.1-0.2 part of benzotriazole, 7-9 parts of gypsum fiber, 1.8-2.5 parts of ferrocenecarboxylic acid, 6-8 parts of methyldiethanolamine, 1.5-1.8 parts of dodecyl trimethyl ammonium chloride, and suitable water; by combining with the advantages in PET resin and polyvinylidene fluoride, the properties of the composite, such as corrosion resistance, wear resistance and impact resistance, are improved; by combining the added carbon fiber and zinc powder to the materials, the prepared composite has good electrical conductivity, significant antistatic effect, light weight and high strength; when used in engineering plastic, the composite has the properties meeting normal use, is easier to cut, and is highly worthy of marketing and application.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a special PET / montmorillonite nanocomposite material for engineering plastics and a manufacturing method thereof. Background technique [0002] Polyethylene terephthalate (PET) is a saturated linear thermoplastic engineering plastic. Its trim and waste products can be recycled. The chemical elements contained in it are carbon, hydrogen, and oxygen like paper, and it is a degradable plastic. PET bottles are light in weight, high in strength, colorless and transparent, high in surface gloss, glassy in appearance, good in plasticity and mechanical properties, and non-toxic and tasteless. In recent years, ordinary PET bottles have been widely used in the packaging of carbonated beverages, mineral water and pure water, becoming the most important form of beverage packaging in the world. However, there are some restrictive factors in the application of PET: poor melt strengt...

Problems solved by technology

[0004] However, the PET / MMT nanocomposite material prepared in this paper is only used in liquid packaging. In terms of engineering plastics, when used in automotive decoration, electronic appliances, mechanical parts, etc., its electrical conductivity is poor, and the antistatic effect is not ideal. It is easy to accumulate dust and even cause fire accidents due to static electricity, so it needs to be modified
