A kind of organic rigid reinforced toughened alloy pipe material for drainage and preparation method thereof

Abstract

The invention discloses an organically rigid reinforced and toughened alloy pipe for drainage and a preparation method thereof, relating to the technical field of building materials, including an alloy layer, the outside of the alloy layer is covered with a reinforcement layer, and the outside of the reinforcement layer is covered with an impact-resistant layer; The preparation method includes the following steps: B1: prepare the alloy layer, and use a roughening device to roughen the outer surface of the alloy layer; B2: wind and heat-melt the reinforcing layer to the outer surface of the alloy layer; B3: co-extrude the impact-resistant layer into the to the outer surface of the reinforcement layer. The pipe in the present invention is provided with a reinforced layer and an impact-resistant layer on the outside of the alloy layer, the reinforced layer adopts a thermoplastic glass fiber pre-impregnated tape reinforced layer, and the impact-resistant layer is a high-modulus impact-resistant non-elastomeric ternary blend composite material layer , the impact performance is under the condition of 0 degrees Celsius and 2m height, the quality of the drop hammer is increased to 3 times of the original, the real impact rate of the pipe is less than or equal to 5%, the ring stiffness is increased by 2 levels, 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
