Organic rigid reinforced and toughened alloy pipe for drainage and preparation method thereof

Abstract

The invention discloses an organic rigid reinforced and toughened alloy pipe for drainage and a preparation method thereof, and relates to the technical field of building materials. The organic rigid reinforced and toughened alloy pipe comprises an alloy layer, the outer side of the alloy layer is coated with a reinforcing layer, and the outer side of the reinforcing layer is coated with an anti-impact layer. The preparation method comprises the following steps that B1, the alloy layer is prepared, and the outer surface of the alloy layer is subjected to napping treatment through a napping device; B2, the reinforcing layer is wound and hot-melted to the outer surface of the alloy layer; and B3, the anti-impact layer are co-extruded and compounded to the outer surface of the reinforcing layer. According to the pipe, the reinforcing layer and the anti-impact layer are arranged on the outer side of the alloy layer, the reinforcing layer is a thermoplastic glass fiber prepreg tape reinforcing layer, the anti-impact layer is a high-modulus anti-impact non-elastomer ternary blending composite material layer, according to the impact performance, under the condition that the temperature is 0 DEG C and the height is 2 m, the drop hammer quality is improved to 3 times of the original drop hammer quality, the actual impact rate of the pipe is smaller than or equal to 5%, the ring stiffness is improved by two grades, and the mass is reduced by 10%-30%.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an organic rigidity reinforced and toughened alloy pipe for drainage and a preparation method thereof. Background technique [0002] Pipe is the material used to make pipe fittings. Different pipe fittings use different pipe materials, and the quality of the pipe directly determines the quality of the pipe fittings. Such pipes are often used in construction projects, power plants, and chemical plants. Pipes are necessary materials for construction projects. Commonly used are water supply pipes, drainage pipes, gas pipes, heating pipes, wire conduits, rainwater pipes, etc. Alloy pipe is one of the common materials in pipe. [0003] A Chinese patent discloses a high-strength magnesium alloy extruded seamless pipe and its preparation process (publication number: CN103627938B). The composition of the pipe in this patent is: Gd: 8.0-10.0%; Y: 1.0-3.0% ; Zn: 0-1.0%; Zr: 0...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the above-mentioned existing alloy pipes that are easily impacted during transportation and use when they are used in drainage projects, the existing alloy pipes have weak impact resistance and are prone to deformation after being impacted. When impact resistance is required, the thickness needs to be increased, resulting in technical problems that increase cost and weight. The purpose of the present invention is to provide an organically rigid reinforced toughened alloy pipe for drainage and a preparation method thereof
