Problems solved by technology

With the enhancement of people's awareness of environmental protection, the advantages of polyurethane exterior wall coatings such as non-toxic, cheap, safe, and non-combustible have shown huge market prospects. Long film time, water resistance, acid resistance, alkali resistance, scrub resistance, stain resistance, artificial aging resistance and other defects, and there are few special coatings for granaries, and the requirements for granary wall coatings are higher
At present, granary wall coatings have low moisture resistance, poor thermal insulation and no fireproof performance in rainy days.

Abstract

The invention discloses special paint for a granary wall body and a preparation method thereof. The paint is prepared by taking polyurethane, hollow glass microsphere, blast furnace slag, titanium white powder, bamboo charcoal, vermiculite powder, perfluorohexyl ethanol, acetyl tributyl citrate, polyethylene wax, organic silicon, a de-foaming agent, a thickening agent, a flame retardant and a dispersant as raw materials; the paint has very high low temperature resisting performance, high moisture-proof performance and very high waterproof performance; the mechanical strength and adhesion forceof a paint film are enhanced and cracks are prevented; the paint is used for preventing ultraviolet rays and water from penetrating through the paint film and the service life of the paint film is prolonged; the paint has the advantages of heat insulation and heat preservation, and high moisture-proof performance, insect-proof performance and fireproof performance.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a special coating for granary walls and a preparation method thereof. Background technique [0002] A granary is a special building for storing grain. my country is a large agricultural country with a long history of food production and storage. According to a large number of cultural relics and historical research unearthed in China in the past fifty years, China’s primitive agriculture was enlightened in the late Paleolithic Age and developed in the New Era (about one year ago) million years or so). The storage of grain is the continuation of agricultural cultivation, and storage technology develops along with the development of agriculture. After entering the new era, with the development of primitive agriculture, agricultural production has formed a certain scale, and grain surplus has gradually developed from grain processing to storage. [0003] At present, in order to implement t...
