Abstract

The invention discloses a waterproof and acid-and-alkali-resistant heat insulation brick for building. The waterproof and acid-and-alkali-resistant heat insulation brick is prepared from the following raw materials in parts by weight: 3 to 7 parts of modified castor oil, 4 to 6 parts of polyalkyl acrylate, 4 to 10 parts of hydroxy propyl cellulose, 1 to 2 parts of bakelite powder, 6 to 12 parts of sepiolite powder, 10 to 18 parts of fly ash, 6 to 12 parts of aluminum oxide, 3 to 7 parts of sodium silicate, 30 to 50 parts of attapulgite and 6 to 10 parts of mica powder, wherein the modified castor oil is prepared from the following processes that opal powder, sodium polyacrylate and water are ground; crystallized TiO2 is added for continuous grinding; water is added for stirring; centrifugal separation is performed; a filter cake is washed by deionized water; drying and crushing are performed to obtain prefabricated materials; the castor oil is subjected to vacuum drying according to the weight parts; vacuum elimination is performed; cooling is performed; 4,4'-diphenylmethane diisocyanate and the prefabricated materials are added in the stirring state; the mixture is continuously stirred; the temperature is raised; the stirring is continuously performed; the stirring is performed again in the vacuum state; the temperature is lowered to the room temperature to obtain the modified castor oil.

Description

technical field [0001] The invention relates to the technical field of thermal insulation bricks, in particular to a waterproof, acid and alkali resistant thermal insulation brick for buildings. Background technique [0002] Insulation materials are generally materials whose thermal coefficient is less than or equal to 0.2. Insulation materials can often achieve twice the result with half the effort in industry and construction with good insulation technology and materials. The thermal insulation material has the characteristics of low density, high flexibility, waterproof, etc., can collect excess heat, has good randomness, has no cavity, and can avoid tearing and falling off under negative wind pressure. Thermal insulation materials and products are an important factor affecting building energy conservation. The development and application of building thermal insulation materials have attracted more and more attention from all over the world. [0003] As a building insula...
