Resin adhesive for bonding thermosetting plastics and thermoplastic plastics and preparation method and application thereof

Abstract

The invention relates to an adhesive and particularly discloses a resin adhesive for bonding thermosetting plastics and thermoplastic plastics and a preparation method and application thereof. The resin adhesive for bonding the thermosetting plastics and the thermoplastic plastics is prepared from the following raw materials in parts by weight: 800-1,000 parts of o-xylene or m-xylene, 280-450 parts of chlorinated polypropylene, 15-42 parts of styryl diethoxysilane, 2-6 parts of acrylonitrile, 1-3.5 parts of di-tert-butyl ether peroxide, 5-15 parts of acrylic acid and 4-6 parts of dimethacrylate-diester. The resin adhesive and the preparation method thereof have the beneficial effects that the raw materials are easily purchased, the cost is low, the toxicity is low, the use is convenient, the bonding is firm, a glass fiber reinforced plastic pipe which is formed through winding glass fibers after the glass fibers are subjected to resin infiltration is tightly combined with an inner pipe so as to form an integer, the split slippage of the inner pipe and an outer pipe is avoided, the coefficient of heat conductivity is large, and the heat resistance is good, so that the problem of bonding between the thermosetting plastics and the thermoplastic plastics is solved effectively, and the resin adhesive is used for bonding the thermosetting plastics (especially glass fiber reinforced plastics) and the thermoplastic plastics (especially polypropylene materials).

Description

(1) Technical field [0001] The invention relates to an adhesive, in particular to a resin glue for bonding thermosetting plastics and thermoplastic plastics, a preparation method and application thereof. (2) Background technology [0002] There are basically two types of pipe materials used for plastic cable protection in the market, one is thermosetting plastics, mainly fiberglass pipes, and the other is thermoplastics, mainly PVC, polyethylene, and polypropylene pipes. The advantages and disadvantages of the pipes of these two types of materials are as follows: [0003] Advantages of FRP cable protection pipes: (1) FRP pipes are light in weight, high in rigidity, and strong in compression and subsidence resistance; (2) Large in thermal conductivity and good in flame retardancy, especially when cables are operated underground for a long time; (3) Good weather resistance, the service life can reach 50 years in the environment of -40 ℃ ~ 150 ℃. FRP cable protection pipes ar...

AI Technical Summary

Problems solved by technology

There has been a composite cable protection tube in the market that utilizes the advantages of thermoplastic materials and thermosetting materials to organically combine FRP and polypropylene. However, it simply uses FRP as the outer tube and polypropylene as the inner tube. The method of direct combination, because thermoplastic is a very typical non-polar crystalline material, has low surface tension, large shrinkage rate, poor creep resistance, poor dimensional stability of the product, and is prone to warping deformation. It is difficult to combine with other The material is adsorbed together, causing a gap between the two materials of the pipe, and even the inner pipe will be pulled out during the process of pulling the cable, which cannot meet the purpose of the market. Therefore, it is necessary to develop an adhesive to make the thermosetting Plastics and thermoplastics can be bonded firmly to prevent the inner and outer tubes from splitting and slipping
