Abstract

The invention discloses special adhering resin for a plastic-lined steel pipe and a preparation method thereof, and belongs to the technical field of macromolecular materials. The special adhering resin is prepared from the following raw materials in parts by weight: 100 parts of polyolefin, 2 to 4 parts of dibutyl maleate, 1 to 3 parts of carbic anhydride, 3 to 7 parts of styrene, 0.05 to 0.4 part of initiator, 0 to 2 parts of antioxidant, and 2 to 5 parts of acetone. The special adhering resin has the advantages that under the synergistic action of multiple monomers of dibutyl maleate, carbic anhydride, styrene and polyolefin, the grafting rate and grafting efficiency are improved; while the requirement of high grafting rate is met, the low residue content is realized, and the utilization rate of polyolefin is high; the special adhering resin is specially designed for the plastic-lined steel pipe, the adhering force with a galvanized pipe, a stainless steel pipe, tinplate and other metals is good, and the special adhering resin is suitable for various types of cold water and hot water plastic-lined pipelines.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a special adhesive resin for plastic-lined steel pipes and a preparation method thereof. Background technique [0002] With the development of science and technology, the market has higher and higher requirements on the performance of metal-plastic composite materials, especially the adhesive layer resin, such as adhesive performance. At present, domestic adhesive resins have relatively low bonding strength to metals, especially to steel and copper. The adhesive performance of the resin is not only related to its grafting rate, but also closely related to its wetting performance and cohesive energy. In order to obtain an adhesive resin with excellent performance, it is necessary to increase the grafting rate of the resin, and the adhesive resin should have suitable wetting properties and high cohesive energy. [0003] Plastic-lined steel pipes are based on galvanized ...
