Abstract

The invention relates to the technical field of binders and particularly relates to a plastic binder. A base material of the plastic binder disclosed by the invention is an acrylonitrile-styrene resin copolymer, a plasticizer is a dibutyl ester type compound, and an antioxidant, gas phase process white carbon black and a solvent are additionally added. The invention further relates to a preparation method of the plastic binder, and the preparation method comprises the following steps of: adding the solvent into a reaction kettle, putting in the gas phase process white carbon black and stirring till complete dissolution; putting in the acrylonitrile-styrene resin copolymer and stirring till complete dissolution of the acrylonitrile-styrene resin copolymer; and adding the antioxidant and the dibutyl ester type compound and stirring to obtain the plastic binder. The plastic binder disclosed by the invention has the advantages of environmental friendliness, good storage performance, low production cost and wide range of application, and the binding strength achieves the national standard. The plastic binder disclosed by the invention is convenient to prepare, simple in conditions, safe and reliable, and the base material can select waste plastic of SAN (styrene-acrylonitrile) resin so as to realize recycling of the waste of the base material, avoid the waste of resources and be suitable for industrial production.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a plastic adhesive and a preparation method thereof. Background technique [0002] At present, the existing plastic adhesives have the following disadvantages: short shelf life, poor storage performance, and yellowish product color; the product is packaged in an iron can, which will rust the iron can and turn the color black; and the adhesive strength is low, Production costs are high. The scope of use is narrow, and it can only be applied to the bonding of PVC pipes and fittings; the toxicity is high, and mass production and sales are restricted. For example: currently on the market, the base material is a plastic adhesive made of high-chlorinated polyvinyl chloride, which has dark color, high toxicity, heavy odor, poor oxygen resistance, and poor storage performance; the normal shelf life is generally 5-7 months. When the temperature is low, it will thicken, deteriorate, or...
