Problems solved by technology

[0003] Coatings mainly include 3 types of inorganic coatings, organic coatings and organic-inorganic composite coatings. Organic coatings have excellent adhesion and stamping properties, but poor heat resistance and weldability; The coating has been widely used due to the combination of various performance requirements. However, the current coatings have insufficient adhesion and corrosion resistance, and their service life cannot meet people's needs. They do not have fire resistance and insulation.

Abstract

The invention discloses an environment-friendly insulating paint for doors / windows, which comprises self-made aluminum dihydrogen phosphate, an organic resin, a filler, an assistant and a solvent. The organic resin is a mixture of an epoxy resin and a water-based polyurethane modified epoxy resin in a mass ratio of 1:5-1:2. The filler is one or mixture of more of barium sulfate, talcum powder, zinc phosphate, aluminum phosphate and titanium dioxide. The assistant comprises a chelator, a dispersing agent, a defoaming agent, a curing agent and a silane coupling agent. The solvent is deionized water or n-butanol. The invention also discloses a preparation method of the environment-friendly insulating paint for doors / windows, which is simple and easy to implement and is pollution-free in the preparation process. The environment-friendly insulating paint has the advantages of favorable adhesiveness, favorable corrosion resistance, favorable fire resistance, favorable insulativity, environment friendliness and higher safety, and prolongs the service life of the door / window.

Description

technical field [0001] The invention belongs to the field of paint preparation, and in particular relates to an environmentally friendly insulating paint for doors and windows and a preparation method thereof. Background technique [0002] With the development of the economy and the improvement of people's living standards, people's requirements for the quality of life are getting higher and higher, and the requirements for daily necessities are getting higher and higher. Doors and windows provide people with a warm and quiet environment in people's lives. Pay attention to the airtightness, service life and appearance of doors and windows. Most of the doors and windows in real life are alloy doors and windows, and there are a series of other doors and windows such as plastic doors and windows. However, these doors and windows have short service life, are easy to corrode, and the appearance is not very beautiful. The method of anti-corrosion and prolonging the life of a singl...
