Background technology
Building coating has decoration functions, defencive function and livability and improves function.Proportion shared by various functions is because making
It is not quite similar by purpose difference.Decoration functions is the function beautifying the appearance value improving it by building.Mainly
Including the concept in terms of plane color, pattern and gloss and the concept of three-dimensional pattern.But will be with building itself
The size and shape of moulding and base material itself matches, and just can fully play out.Defencive function refers to protect building not
Function that is protected from environmental and that destroy.Different types of content required defencive function by protective is the most different.As
The index difference reached required by indoor and outdoor application is the biggest.Some buildings are to mildew-resistant, fire prevention, insulation, corrosion resistant
Erosion etc. has particular/special requirement.Livability improves function mainly for indoor application, it is simply that contribute to improving the merit of living environment
Can, such as sound-proofing, sound absorption properties, anti-condensation etc..According to typoiogical classification (1) liquid coating of building coating, (2) powdery paints;
It is divided into organic Xu material, inorganic coating, composite coating according to the character of main film forming substance;It is divided into plane to be coated with according to the state of film
Material, sand texture coating, complex layer coating;By the using method of building be divided into exterior wall Xu material, interior wall coating, ceiling coating, topcoating
Material, roof paint;It is divided into water-repellent paint, fireproof coating, anticorrosive paint, mildew resistant paint, insect paint by the performance of film, is helped rust
Coating, antifogging coating.
Summary of the invention
For the deficiencies in the prior art, it is an object of the invention to provide a kind of anti-stick interior wall coating of anticracking, be primarily suitable for
The spraying of inner side body of wall, it is possible to be applicable to the spraying of exterior wall, processing technology is simple, with low cost, and coating is difficult to pick resistance
Good, effect of anti-cracking is good.
Technical scheme is as follows:
A kind of anti-stick interior wall coating of anticracking, is made up of following component in parts by weight: red mud 30-40 part, zeolite powder 10-12 part,
Flyash 5-7 part, powdered rice hulls 6-8 part, blast-furnace cinder 3-5 part, SGA 4-6 part, drier 2-4 part, tossa 3-5
Part, carbon black powder 2-4 part, sodium bentonite 4-6 part, hydrochloric acid 2-4 part, calcium phosphate 0.3-0.5 part, sodium hydroxide 1-2 part, asphalt mixtures modified by epoxy resin
Fat 5-7 part, polyvinyl alcohol 2-4 part, water 50-60 part, fire retardant 1-2 part;Its preparation method comprises the steps:
(1) by powdered rice hulls, flyash, zeolite powder 10-20% soak with hydrochloric acid 1-2 hour, then steam with 8-10% sodium hydroxide
Boiling 1-1.5 hour, temperature is set as 70-80 DEG C, obtains mix products;
(2) after red mud, blast-furnace cinder, sodium bentonite and appropriate water being mixed, through 500-600 DEG C of calcining, after calcining
Product put into comminutor, through pulverizing after formed granularity 1-3mm intermediate product, then by intermediate product, carbon black powder,
High-speed stirred 20-30 minute after tossa, epoxy resin, calcium phosphate and the mixing of remaining water, obtains mixed slurry;
(3) product obtained in above-mentioned steps (1), (2) is mixed with other remaining ingredients, stir, be heated to 120-
150 DEG C, temperature retention time is 2-3 hour, and stove is cooled to 50 DEG C, and temperature retention time is 2-3 hour, is again heated to 100-120 DEG C, during insulation
Between be 0.8-1.2 hour, be cooled to room temperature with 10 DEG C/h, i.e. prepare coating.
The anti-stick interior wall coating of anticracking, is made up of following component in parts by weight: red mud 35 parts, zeolite powder 11 parts, flyash 6
Part, powdered rice hulls 7 parts, blast-furnace cinder 4 parts, SGA 5 parts, drier 3 parts, tossa 4 parts, carbon black powder 3 parts, sodio are swollen
5 parts of profit soil, hydrochloric acid 3 parts, 0.4 part of calcium phosphate, sodium hydroxide 1.5 parts, epoxy resin 6 parts, polyvinyl alcohol 3 parts, 55 parts of water, fire-retardant
Agent 1.5 parts.
Compared with prior art, there is advantages that
It is an advantage of the current invention that: coating is primarily suitable for the spraying of inner side body of wall, it is possible to be applicable to the spraying of exterior wall, Qi Zhongtian
Add the raw material such as carbon black powder, zeolite powder, carbon black: being a kind of amorphous carbon, light, loose and superfine black powder, surface area is very
Greatly, scope is from 10 ~ 3000m2/ g, be carbonaceous material under conditions of lack of air through obtained by imperfect combustion or decomposes
Product;Zeolite powder: have stronger carrying capability, not only can make material adsorb on surface equably, and can be adsorbed onto hole
With in passage, the utilizability that improve material is also substantially improved the uniformity of mixing;Processing technology is simple, with low cost, tool
Having the function of anticracking, difficult drop-off, security performance is good.
Detailed description of the invention
A kind of anti-stick interior wall coating of anticracking, is made up of following component: red mud 35 parts, zeolite powder 11 parts, powder in parts by weight
Coal ash 6 parts, powdered rice hulls 7 parts, blast-furnace cinder 4 parts, SGA 5 parts, drier 3 parts, tossa 4 parts, carbon black powder 3 parts,
Sodium bentonite 5 parts, hydrochloric acid 3 parts, 0.4 part of calcium phosphate, sodium hydroxide 1.5 parts, epoxy resin 6 parts, polyvinyl alcohol 3 parts, water 55
Part, fire retardant 1.5 parts;Its preparation method comprises the steps:
(1) by powdered rice hulls, flyash, zeolite powder 15% soak with hydrochloric acid 1.5 hours, then it is little to carry out steaming and decocting 1.3 with 9% sodium hydroxide
Time, temperature is set as 75 DEG C, obtains mix products;
