Abstract

The invention provides a special instant adhesive for a PVC (polyvinyl chloride) pipeline and a preparation method of the special instant adhesive, and relates to the technical field of tackiness agent processing. The instant adhesive is prepared from the following raw materials in parts by weight: 30-40 parts of epoxy resin, 20-30 parts of cyanoacrylate, 12-18 parts of PVC resin, 2-3 parts of vinyl acetate, 3-6 parts of acrylic acid, 2-4 parts of thiodipropionic acid diester, 1-2 parts of copper chloride, 0.8-1.4 parts of plasticizer, 0.6-1.2 parts of flexibilizer, 1.4-1.8 parts of stabilizer, 8-10 parts of hydrogen peroxide and 6-10 parts of ethyl acetate. The special instant adhesive overcomes defects in the prior art, the drying time of the PVC pipeline is greatly reduced when the heatresistance and corrosion resistance of rubber used for the PVC pipeline are simultaneously guaranteed, and the special instant adhesive further has the advantages of high strength, high flexibility and high stability, and thus being suitable for practical production use.

Description

technical field [0001] The invention relates to the technical field of adhesive processing, in particular to a special quick-drying adhesive for PVC pipes and a preparation method thereof. Background technique [0002] Due to the advantages of excellent bonding performance, corrosion resistance, small fluid resistance, water tightness, anti-biting, and low price, PVC pipes are widely used in municipal water supply and drainage, industrial water supply and drainage, civil water supply and drainage, irrigation, and vegetation watering , chemical and domestic wastewater, chemicals, heating fluid and cooling fluid, food, ultrapure liquid, mud, gas, compressed air and vacuum systems, etc. In the actual use of PVC pipes, multiple pipes often need to be connected by adhesive bonding. become. [0003] At present, the organic solvents of PVC pipe adhesives mainly used in the market are highly toxic, and a large amount of organic solvents remain on PVC pipes, causing harm to constru...
