Problems solved by technology

Especially in the indoor environment, the dead corners such as bedside tables, bed boards, and wardrobes are not easy to clean, so that mites can breed in large numbers in these dead corners
The existing technology mainly uses ultraviolet light to kill mites and acaricide spray to remove and kill mites. The effect of ultraviolet light to kill and remove mites is low, and the recurrence rate of mites is high. Every once in a while, it is necessary to remove mites again. The acaricide spray uses chemical means to remove mites. Mites are harmful to the human body

Abstract

The invention relates to the technical field of coatings and in particular to an anti-mite oily PU (Polyurethane) transparent finishing coat and a preparation method thereof. The weight ratio of a component A to a component B is 2:(0.5-1.5), the component A consists of the following components in percentage by weight: 75-80% of a high-solid component polyhydric alcohol resin, 5-10% of an ester type solvent, 0.5-1% of a dispersant, 5-12% of an inorganic anti-mite agent, 0.3-0.7% of a defoaming agent, 0.05-0.15% of a leveling agent and 1-5% of an anti-sinking agent; the inorganic anti-mite agentconsists of borate, an alkaline-earth metal and silicate; the particle size of the inorganic anti-mite agent is 5-15mu m; the component B consists of the following components in percentage by weight:35-45% of a TDI (Toluene Diisocynate) tripolymer, 30-40% of a TDI additive product and 20-30% of n-butyl acetate. The preparation method mainly has a step of material mixing operation. The PU transparent finishing coat has the characteristics of good anti-mite effects and environmental protection.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an anti-mite oily PU transparent topcoat and a preparation method thereof. Background technique [0002] In recent years, in order to meet consumers' pursuit of environmentally friendly coatings, existing coatings pay more attention to the properties of "low VOC", "low TDI", "low odor" and "anti-mold and antibacterial" properties of coatings, but rarely pay attention to the performance of coatings in Research and development of anti-mite performance. [0003] In fact, allergies caused by mites have become a worldwide problem. Mites can enter the digestive tract or respiratory system of the human body through daily diet or breathing, thereby causing a series of respiratory diseases; the bite of mites may also cause skin diseases. In addition to directly causing diseases, mites can also carry and infect various insect diseases. Especially in the indoor environment, the dead corn...
