Polymer alloy composite cement water supply pipe and manufacture method thereof

Abstract

The invention provides a polymer alloy composite cement water supply pipe which sequentially comprises a cement layer, a bonding layer, an interface compatible layer and an overflowing layer from outside to inside. The bonding layer adopts fibers to serve as polyamide modified epoxide resin composite materials of a reinforcing material, the overflowing layer is a resin modified polymer alloy material layer, and the interface compatible layer is a coupling reagent connecting the bonding layer and the overflowing layer. A manufacture method particularly comprises the following steps of prefabricating the cement layer, enabling the fibers to be soaked by liquid state polyamide modified epoxide resin, bonding the fiber on an inner wall of the cement layer, and solidifying for 4 hours at the temperature of 80-100 DEG C or conducting normal temperature solidification for 240 hours; spraying the liquid state polyamide modified epoxide resin on an inner surface of the bonding layer, evenly pasting resin modified polymer alloy material sheets of soaked by the liquid state coupling reagent, and solidifying for 4 hours at the temperature of 100 DEG C or conducting normal temperature solidification for 240 hours. The polymer alloy composite cement water supply pipe has performance such as corrosion resistance, aging resistance, impact resistance, zero poison, innocuity, zero pollution, wear resistance, high strength and the like.

Description

technical field [0001] The invention relates to the field of production and processing of building materials, in particular to a brand-new polymer alloy composite cement water supply pipe and a manufacturing method thereof. Background technique [0002] At present, the water supply pipes used in operation and transportation generally include several types such as metal pipes, plastic pipes and cement pipes, but they all have many shortcomings, as follows. Although the metal pipe has high strength, it is easy to rust and corrode. After rust and corrosion, the metal pipe will be blocked, broken and leaked; The light and color masterbatches are easy to separate out and enter the water, which will affect the quality of the conveyed water; the cost of the cement pipe is low, but its strength is low, and the part in contact with the water is easy to slowly decompose during use, which not only affects the water quality, but also after a period of use. The body is also prone to dis...
