Abstract

The invention discloses an adhesive for water pipes and a preparation method thereof. The preparation method includes the steps that after acacia gum, sodium alga acid, phenolic resin, alkyd resin and polyvinyl chloride are mixed and stirred, a basic mixed solution M is formed; after the basic mixed solution M, white carbon black, an emulsifying agent and a stabilizer are mixed, the adhesive for the water pipes is obtained. By the adoption of the adhesive for the water pipes and the preparation method thereof, the problems are solved that when a current adhesive is adopted to connect adjacent plastic pipes, the needed curing time is relatively long, and besides, it is difficult for glued pipelines to meet the requirements for high-pressure pipelines in the aspect of bearing water pressure.

Description

technical field [0001] The invention relates to an adhesive, in particular to an adhesive for water pipes and a preparation method thereof. Background technique [0002] At present, plastic water pipes are widely used in industrial production and life, wherein the laying of plastic pipes often connects two adjacent PVC pipes through adhesives. The use of existing adhesives to connect adjacent plastic pipes not only requires a long curing time, but also the bonded pipes cannot meet the requirements of high-pressure pipes in terms of water pressure. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an adhesive and its preparation method, which solves the problem that the existing adhesive not only needs a long curing time to connect adjacent plastic pipes, but also the bonded pipes are not easy to bear in terms of water pressure. It is also difficult to meet the requirements of high-pressure pipelines. [0004] In ...
