Problems solved by technology

In this way, no matter whether it is rigid waterproof or flexible waterproof, it cannot be combined with the base surface of the water supply equipment as a unified whole.
Therefore, it is easy to appear delamination, cracking, aging, falling off, etc., which seriously affects the quality and effect of waterproofing, and cannot truly perform anti-corrosion and leak-proof performance on water supply equipment, thereby reducing the service life of water supply equipment.

Abstract

The invention provides a preparation method of a waterproof material of water supply equipment. The method comprises the following steps that a, modified calcium carbonate, filler, lightweight calciumcarbonate and quartz sand are mixed and crushed; then, ultrasonic dispersion is performed to obtain a powder mixture; b, organic rubber, a polyurethane material, a composite material and asphalt aremixed and smelted; then, a compound emulsifying agent is added; stirring reaction is performed to obtain a first mixture; c, a low-temperature-resistant modifying agent is added into the first mixture; stirring and heating are performed; then, the powder mixture is added; stirring is performed to obtain a second mixture; d, a thickening agent, water and a defoaming agent are added into the secondmixture; heating and stirring are performed into a sticky state; the waterproof material is obtained. The prepared waterproof material has excellent characteristics of cold resistance, heat resistance, aging resistance, antibiosis, environment-friendly effect, long service life and the like.

Description

technical field [0001] The invention belongs to the technical field of waterproof materials, and in particular relates to a preparation method of waterproof materials used for water supply equipment. Background technique [0002] At present, there are two kinds of waterproof materials used for water supply equipment: one is rigid waterproof; the other is flexible waterproof. Among them, the commonly used rigid waterproof is to add a concrete mortar waterproof layer on the base surface of the water supply equipment. This kind of waterproof layer is not tightly combined with the base surface, and the waterproof layer itself has molecular voids, which are easy to corrode and expand under the action of water, resulting in cracking of the waterproof layer and losing the anti-corrosion and water-leakage effects. Similarly, the flexible waterproofing commonly used at present is to brush organic waterproof coatings on the base surface of the water supply equipment to form a protect...
