Abstract
The heat insulating material is used for heat insulation in metallurgy, petroleum, electric power, heating, building and other fields. During its preparation, polyacrylamide is first soaked in 400 times of water for 12 hr to become ropy solution; silica powder, calcified cotton, pearlite and light calcium carbonate are then mixed together, and the mixture is finally mixed with polyacrylamide solution and modifying water glass into the heat insulating material. The material is innocuous, light and hard, has stable fireproof, heat insulating and sound isolating property as well as heat resisting temperature as high as 1300 deg.c, and may be produced into paste for painting or powder for spraying.
Description
The present invention relates to a kind of asbestos-free inorganic heat insulating coating material for wall, this product can be widely used in the adiabatic heat-insulation of industrial neck such as metallurgy, oil, electric power, heating, building, traffic, light industry or differing temps scope.
Common in the market coating all is base-material with asbestos, though asbestos material tool heat insulation function, but there are carcinogens and radiation in it, HUMAN HEALTH is worked the mischief, can only anti-600 ℃ of high temperature, shortcomings such as ubiquity is poisonous, heat retaining property is poor, poor durability, stopping property is poor, calorific loss is big, thereby most of products are confined to low temperature, medium temperature condition uses down, its fire resistance is relatively poor, country progressively forbids making interior wall heat insulation material with asbestos at present, therefore is badly in need of a kind of novel substitute products.
The purpose of this invention is to provide a kind of asbestos-free inorganic fire-proof heat-insulating insulation and sound damping inorganic heat insulating coating material for wall.
For achieving the above object, technical scheme of the present invention is:
The prescription of asbestos-free inorganic heat insulating coating material for wall is: (following material is counted by ratio of weight and the number of copies)
30 parts of modified water glass (modulus 3.5)
Polyacrylamide 0.1-0.2 part
Conspicuous silica flour (containing silicon-dioxide 99%) 15-25 part
Calcification cotton (aluminium silicate wool processes with calcium oxide) 50-75 part
Perlite 20-30 part
Light calcium carbonate 5-7 part
Water is an amount of;
Its production craft step is:
1, polyacrylamide adds 400 parts in water, soaks to make it to become viscous solution in 12 hours, and is standby;
2, conspicuous silica flour, calcification cotton, perlite, light calcium carbonate mixing stirring add polyacrylamide solution then and stirred abundant 30 minutes;
3, add modified water glass at last, continue to stir, get final product.(modified water glass adds 3% water-repellent agent, 2% coupling agent fully stirred about 1 hour)
The solids content of all cpds of the present invention: silicon-dioxide 75%, aluminium sesquioxide 30%, light calcium carbonate 7%.This product is nontoxic, harmless, pollution-free, lightweight, hard, stable performances such as its fire prevention, thermal insulation, insulation, sound insulation, sound absorption all are higher than like product, use back outward appearance flawless and damage, high temperature resistantly reach 1300 ℃, spraying, trowelling all can, easy for operation, by control moisture, both can be made into lotion coating, can be made into dry powder paint again, be easy to transportation, packing, keeping, long quality-guarantee period.
