Problems solved by technology

This patent can achieve full infiltration of continuous fibers through the solution impregnation process, and can produce chain extension reaction after co-vulcanization with rubber to improve the bonding strength. Oxazoline and cycloethylene glycol will cause VOC problems, which is not conducive to environmental protection, and construction efficiency and environmental protection problems cannot meet the requirements of modern industrial systems

Abstract

The invention discloses an adhesive resin for continuous fiber-reinforced plastic composite pipes, which is prepared from the following components in percentage by weight: polyolefin grafted silane 7-40%, reactive polyurethane 1-10%, 0.1-10% compatibilizer, 30-80% polyolefin matrix resin, 5-35% elastomer tackifying resin, 0.1-2% processing anti-aging additive. The invention also provides a preparation method of the adhesive resin for the continuous fiber reinforced plastic composite pipe. The bonding resin of the present invention has a good bonding effect on continuous fiber materials such as continuous glass fiber, polyester fiber, nylon fiber, aramid fiber, carbon fiber, etc., and the continuous fiber reinforced thermoplastic pipe prepared by it has a multi-layer structure, many The bonding between the layers is firm, the pressure bearing capacity is high, and the weight is light. It is an excellent choice in the field of high-pressure pipes.

Description

technical field [0001] The invention relates to the field of material compositions, in particular to an adhesive resin for continuous fiber reinforced plastic composite pipes and a preparation method thereof. Background technique [0002] Continuous fiber is a kind of continuous high-strength fiber, commonly used are glass fiber, polyester fiber, nylon fiber, aramid fiber, carbon fiber, etc., which have excellent properties such as high strength, high toughness, insulation and heat resistance, and are used in aerospace, automotive, etc. , clothing, military industry, building materials and many other aspects. Polyolefin adhesive resin has good wettability and high bonding strength for various materials including some non-polar materials. At the same time, as an environmentally friendly material, it also has excellent processing. In terms of operation, it can be applied to high-speed continuous The production line improves production efficiency and is widely used in composit...
