Abstract

The invention discloses a steel belt corrugated pipe and a preparation method thereof. The steel belt corrugated pipe comprises an inner layer, a steel belt and an outer layer, the steel belt is positioned between the inner layer and the outer layer, and each of the inner layer and the outer layer is prepared from, by weight, 80-93 parts of polyvinyl chloride and polyethylene blend, 7-11 parts ofsolubilizer, 0.1-0.5 part of antioxidant, 1-3 parts of plasticizer, 5-8 parts of reinforcing material and 0.5-1.2 parts of stabilizer. The steel belt corrugated pipe has the advantage of excellent performance. The preparation method includes: mixing raw materials, and melting at 140-180 DEG C for 15-25min to obtain melt; treating the steel belt: uniformly coating the surface of the steel belt withadhesive resin; utilizing hot melt connecting technology to complete adhesive compositing of the melt and the steel belt with the adhesive resin, and cooling for shaping to obtain the steel belt corrugated pipe. The preparation method has the advantages of being simple in preparation step, convenient in operation, easy in implementation, convenient for mass production and environment-friendly.

Description

technical field

[0001] The invention relates to the technical field of pipelines, more specifically, it relates to a steel strip corrugated pipe and a preparation method thereof. Background technique

[0002] Steel belt corrugated pipe generally refers to belt-reinforced spiral corrugated pipe, which uses U-shaped steel belt composite PE material, so that the ring stiffness of the pipe can be greatly improved without increasing the cost, and the strength of the pipe is greatly improved compared with the winding pipe and the carat pipe under the same weight. . It can solve a series of problems such as heavy loads, and the advantages of large-diameter pipes are more obvious. The diameter of the produced pipes ranges from DN300mm to DN2400mm, and the ring stiffness is kept above 8KN / m2, which is lighter and stronger than cement pipes and other plastic pipes. Widely used in drainage and sewage pipes of municipal engineering, construction engineering, water conservancy projects,...
