Heat-insulating paint for internal cavity of chemical pump and preparation method of heat-insulating paint

Abstract

The invention provides heat-insulating paint for an internal cavity of a chemical pump and relates to the technical field of preparation of pump valves. The heat-insulating paint is prepared from the following raw materials in parts by weight: 50-60 parts of chlorinated rubber resin, 25-35 parts of styrene-butadiene rubber resin, 10-20 parts of rutile titanium white, 2-4 parts of coated pearl mica powder, 8-10 parts of ceramic microspheres, 6-8 parts of silicon carbide, 30-40 parts of fluorocarbon resin, 6-8 parts of activated clay, 5-7 parts of polyether rubber, 3-5 parts of toughening assistant, 15-25 parts of gelatin, 15-25 parts of ethylene bisstearamide, 3-5 parts of sodium polyacrylate, 6-8 parts of nano zinc oxide and 120-140 parts of water. The heat-insulating paint has the beneficial effects that the heat-insulating paint is prepared by taking the chlorinated rubber resin as a main raw material and assisting the chlorinated rubber resin with the styrene-butadiene rubber resin, the fluorocarbon resin and a variety of fillers and functional assistants; after the internal wall of the cavity of the chemical pump is coated with the heat-insulating paint, the heat-insulating paint can rapidly cure and form a compact and hard coating, and the coating has excellent flame retardance, high-temperature resistance and heat-insulating property, so that the chemical pump can be effectively protected from damage, the normal operation of the chemical pump is guaranteed, and the service life of the chemical pump is prolonged.

Description

technical field [0001] The invention relates to the technical field of pump and valve preparation, in particular to a heat-insulating paint for an inner cavity of a chemical pump and a preparation method thereof. Background technique [0002] The chemical pump is an energy-saving pump designed jointly by the whole country.

[0002] The chemical pump is an energy-saving pump designed jointly by the whole country. The performance and technical requirements of the pump are designed according to the performance and size stipulated by international standards. Its advantages: the whole series of water conservancy performance is reasonable, the user has a wide range of choices, and the "back-opening" structure , convenient maintenance, efficiency and suction reach the international advanced level, widely used in industrial, urban water supply, drainage, irrigation and drainage of farmland, orchard, for transporting clean water or other liquids with physical and chemical properties similar to clean water, chemical pumps are used in In normal use, due to the long-term fluid flow in the pump cavity, it is subjected to high pressure, and in practical applications, some fluids containing a large amount of particles will be transported through the chemical pump, and some fluids similar to high heat will be transported, so It will inevitably cause the pump body to suffer from a large amount of high temperature, resulting in accelerated aging of the pump body structure, cracking and other problems, and the service time is not long
