Problems solved by technology

Although the hot melt adhesive currently used in PVC-lined steel-plastic composite pipes has a good bonding effect on PVC and steel pipes, it is not versatile and has a low melting point, so it cannot achieve a more ideal effect during processing. and more expensive
In addition, the fluidity of this type of hot melt adhesive products is poor, which affects the efficiency of coating. The production pro

Embodiment 1

[0035] A hot melt adhesive for steel-lined plastic composite pipes is composed of the following components by weight:

[0036] Metallocene polyethylene 70 parts

[0037] Styrene-isoprene-styrene block copolymer 30 parts

[0038] Rosin-modified phenolic resin 15 parts

[0039] 2 parts of vinyltrimethoxysilane

[0040] Polyethylene terminated epoxy wax 0.5 part

[0041] 1 part of tetrakis[methyl-(3,5-di-tert-butyl-4-hydroxyphenyl)propionic acid]pentaerythritol

Abstract

The invention belongs to the field of polymer adhesives, and particularly relates to a hot melt adhesive for a steel plastic-lined composite pipeline and a preparation method of the hot melt adhesive.The hot melt adhesive for the steel plastic-lined composite pipeline comprises, by weight, 100 parts of matrix resin, 15-20 parts of tackifying resin, 1-3 parts of silane crosslinking agents, 0.5-1 part of compatilizers, 0.5-1.5 parts of antioxidants, 0.5-1 part of plasticizers and 20-30 parts of fillers. The hot melt adhesive for the steel plastic-lined composite pipeline is high in adhesive force, good in weather resistance and heat stability, resistant to ageing, acid and alkali, green, environmentally friendly and cannot be limited by the temperature, can be normally used at low temperature and effectively adhere metal and plastics, and the preparation method is simple, easy to operate and low in cost.

Description

technical field [0001] The invention belongs to the field of polymer adhesives, and in particular relates to a hot melt adhesive for steel-lined plastic composite pipes and a preparation method thereof. Background technique [0002] With the rapid development of my country's economy and the continuous improvement of people's quality of life, the rapid development and construction of cities, many occasions require large pipelines to transport gases, liquids, and even fluidized solids. Gases, liquids or liquefied solids transported by many pipelines are themselves flammable, corrosive, and explosive materials. In this case, there are higher requirements for transmission pipelines, such as anti-flammability, anti-static, wear-resistant, Corrosion resistance, anti-leakage, etc. Therefore, traditional engineering specifications can only use cast iron pipes, or large-diameter steel pipes, which are heavy and corrode too quickly. If the friction loss is considered, the cost of use...
