Fireproof wind-sand-resistant paint for desert environment wood ancient building and preparation method of fireproof wind-sand-resistant paint

Abstract

The invention provides fireproof wind-sand-resistant paint for a desert environment wood ancient building and a preparation method of the fireproof wind-sand-resistant paint. The paint comprises a component A and a component B, wherein the mass ratio of the component A to the component B is 1:2; the component A is prepared by adopting the following ingredients in parts by weight: 90 to 120 parts of acrylic polyurethane aqueous dispersion, 0.5 to 1.5 parts of a thickening agent and 5 to 20 parts of deionized water; the component B is prepared from the following ingredients in parts by weight: 2 to 8 parts of PMA, 0.5 to 5 parts of a dispersion agent, 0.2 to 0.8 part of a defoaming agent, 10 to 30 parts of deionized water, 10 to 40 parts of superfine talcum powder, 10 to 40 parts of kaolin, 10 to 30 parts of iron oxide red and 0.8 to 1.2 part of dimethyl methyl phosphonate. The combination force between the prepared paint and an iron tower foundation body is strong, and the prepared paint is environmentally friendly, has wind-sand impact resisting property and can meet the protection requirement of the desert environment wood ancient building. The paint is simple to produce and good in construction performance and does not need high-temperature curing and is rapid to dry at room temperature.

Description

technical field [0001] The invention relates to a paint technology, in particular to a fire-proof and sand-resistant paint for wooden ancient buildings in the Gobi environment and a preparation method thereof. Background technique [0002] Our country is a country with rich traditional culture. Among them, wooden ancient buildings are an extremely important part, from which we can see the development of other sciences in the same period and the level they reached at that time. They are the country's non-renewable precious historical heritage, an important symbol of national civilization, and a precious wealth of the nation. Therefore, the work of protecting ancient buildings is particularly important. At present, there are two problems in the protection of ancient wooden buildings in the Gobi environment: first, various timber components in ancient buildings have good combustion and flame propagation properties. Moreover, the roofs of ancient buildings are tight and tight....

Problems solved by technology

This kind of group is connected, arranged in groups with high and low levels, dense and dense, the cornices of the halls are overlapped, and the corridors are connected, so that the fire prevention distance between the buildings is insufficient, and there is a lack of safe space. It is easy to cause the fire to be uncontrollable. Under such conditions, the fire spread rapidly and became connected, resulting in an uncontrollable situation

Second, if the ancient wooden buildings are impacted or collided by wind and sand for a long time after thousands of years, the wooden structure will be destroyed
