Background technology
Building coating has the function of that decoration functions, defencive function and livability are improved.Proportion shared by various functions is because making
It is not quite similar with purpose difference.Decoration functions are to improve the function of its appearance value by the beautification of building.Mainly
Design design in terms of including plane color, pattern and gloss and the design of three-dimensional pattern design.But it 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 protecting building not
Function that is protected from environmental and destroying.Different types of content required defencive function by protective is also different.Such as
It is indoor just very big with index difference that is reaching required by outdoor application.Some buildings are to mould proof, fire prevention, insulation, corrosion resistant
Erosion etc. has particular/special requirement.Livability improves function mainly for indoor application, just contributes to the work(for improving living environment
Can, such as sound-proofing, sound absorption properties, anti-condensation.According to typoiogical classification (1) liquid coating of building coating, (2) powdery paints;
It is divided into organic Xu's material, inorganic coating, composite coating according to the property of main film forming substance;It is divided into plane according to the state of film to apply
Material, sand texture coating, complex layer coating;It is divided into exterior wall Xu material, interior wall coating, ceiling coating, ground painting by the application method of building
Material, roof paint;It is divided into water-repellent paint by the performance of film, fireproof coating, anticorrosive paint, mildew resistant paint, insect paint, helps rust
Coating, antifogging coating.
Invention content
In view of the deficiencies of the prior art, it the object of the present invention is to provide a kind of anti-stick interior wall coating of anticracking, is primarily suitable for
The spraying of inside wall is equally applicable to the spraying of exterior wall, and manufacture craft is simple, of low cost, and coating is not easy 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 of following component in parts by weight:30-40 parts of red mud, zeolite powder 10-12
Part, 5-7 parts of flyash, 6-8 parts of powdered rice hulls, 3-5 parts of blast-furnace cinder, 4-6 parts of acrylic adhesive, 2-4 parts of drier, tossa
3-5 parts, 2-4 parts of carbon black powder, 4-6 parts of sodium bentonite, 2-4 parts of hydrochloric acid, 0.3-0.5 parts of calcium phosphate, 1-2 parts of sodium hydroxide, ring
5-7 parts of oxygen resin, 2-4 parts of polyvinyl alcohol, 50-60 parts of water, 1-2 parts of fire retardant;Preparation method includes the following steps:
(1) by powdered rice hulls, flyash, zeolite powder 10-20% salt acid soaks 1-2 hours, then with 8-10% sodium hydroxides into
Row boiling 1-1.5 hours, temperature is set as 70-80 DEG C, obtains mix products;
(2) it after mixing red mud, blast-furnace cinder, sodium bentonite and suitable water, calcines, forges by 500-600 DEG C
After burning product be put into comminutor, form the intermediate product of granularity 1-3mm after crushing, then by intermediate product, carbon black
High-speed stirred 20-30 minutes, obtains mixed slurry after powder, tossa, epoxy resin, calcium phosphate and the mixing of remaining water;
(3) by above-mentioned steps(1)、(2)In obtained product mixed with other remaining ingredients, stir evenly, be heated to
120-150 DEG C, soaking time is 2-3 hours, is furnace-cooled to 50 DEG C, and soaking time is 2-3 hours, is again heated to 100-120 DEG C, is protected
The warm time is 0.8-1.2 hours, is cooled to room temperature with 10 DEG C/h, obtains coating.
The anti-stick interior wall coating of anticracking, is made of following component in parts by weight:35 parts of red mud, 11 parts of zeolite powder, flyash 6
Part, 7 parts of powdered rice hulls, 4 parts of blast-furnace cinder, 5 parts of acrylic adhesive, 3 parts of drier, 4 parts of tossa, 3 parts of carbon black powder, sodium base are swollen
It is 5 parts of profit soil, 3 parts of hydrochloric acid, 0.4 part of calcium phosphate, 1.5 parts of sodium hydroxide, 6 parts of epoxy resin, 3 parts of polyvinyl alcohol, 55 parts of water, fire-retardant
1.5 parts of agent.
Compared with prior art, the present invention has the advantages that:
The advantage of the invention is that:Coating is primarily suitable for the spraying of inside wall, is equally applicable to the spraying of exterior wall,
In be added to the raw materials such as carbon black powder, zeolite powder, carbon black:It is a kind of amorphous carbon, light, pine and superfine black powder, surface area
Very big, range is from 10 ~ 3000m2/ g, be carbonaceous material under conditions of lack of air through imperfect combustion or thermally decomposed and
The product obtained;Zeolite powder:With stronger carrying capability, material can be not only set equably to be adsorbed on surface, and can be adsorbed onto
In hole and channel, the utilizability for improving material also substantially improves the uniformity of mixing;Manufacture craft is simple, at low cost
It is honest and clean, have the function of anticracking, not easily to fall off, has a safety feature.
Specific implementation mode
A kind of anti-stick interior wall coating of anticracking, is made of following component in parts by weight:35 parts of red mud, 11 parts of zeolite powder, powder
