Abstract

The invention discloses adhesive resin for steel-mesh reinforcing polyethylene hot water pipe. The adhesive resin comprises, by weight, 5-50% of polyethylene grafts, 20-80% of polyethylene matrix resin, 5-60% of heat-proofness enhancing particles and 1-30% of elastomer toughening particles, and the total percentage of the components is 100%. The invention further discloses a preparation method of the adhesive resin. The adhesive resin prepared is good in heat resistance, steel-mesh adhesive effect is good, vicat softening point reaches more than 120DEG C, heat distortion temperature reaches above 95DEG C, and peel strength at the temperature of 85DEG C reaches more than 100N / cm.

Description

technical field [0001] The invention belongs to the technical field of material composition preparation, and in particular relates to an adhesive resin for steel mesh reinforced polyethylene hot water pipes and a preparation method thereof. Background technique [0002] Steel mesh reinforced polyethylene composite pipe is a kind of reinforced thermoplastic pipe (RTP) that has developed rapidly in more than ten years. It has the characteristics of strong pressure bearing, low linear expansion coefficient, corrosion resistance, no scaling, light weight, environmental protection and non-toxic, etc. . Steel mesh reinforced polyethylene composite pipe combines the respective advantages of thermoplastic and metal reinforcement layers, and achieves the complementary advantages of plastic and metal materials in terms of performance. It is widely used in municipal, chemical, fire-fighting and other fields. Long-term and extensive market application cases show that steel mesh reinfor...
