Description

The building coating that cementability is good

Technical field

The present invention relates to casting field, particularly to the building coating that a kind of cementability is good.

Background technology

For beautifying the environment, improve the appearance of the city or advertising use, a lot of skin bodies are coated with the various coating with aesthetic feeling color. But currently used paint adhesion performance is poor, particularly poor with the cohesive force of cement wall, easy to crack, be full of cracks, even comes off, particularly that the brushing of clear water coagulation basic unit or the cohesive force of spary is all poor, and cost is high, coating chaps or comes off, and reduces the aesthetic feeling of coating and the clean and tidy and harmony of the destructible appearance of the city.

Summary of the invention

For the deficiencies in the prior art, it is an object of the invention to provide the building coating that a kind of cementability is good, this coating is coated on cement based exterior wall, and cohesive force is strong, is not easily cracked and comes off, and to acidproof, alkaline-resisting, fire-resistant, water resistance is good.

Technical scheme is as follows:

The building coating that a kind of cementability is good, is made up of following component with parts by weight: calcium carbonate 35-45 part, lime white 30-40 part, waterglass 4-7 part, schmigel 10-12 part, sodium bentonite 6-10 part, suspending agent 4-6 part, lignin sulfonic acid 1-2 part, ethyl acetate 2-4 part, sodium borate 2-4 part, water-soluble urea-formaldehyde resin glue 5-7 part, nanometer scale ceramics powder 1-2 part, water 85-100 part, concrete preparation process is as follows:

1) waterglass and water-soluble urea-formaldehyde resin glue are mixed in proportion, and add water by water inventory 10%-20%, dissolve for liquid with standby at high temperature 80 DEG C-90 DEG C, glue carries out coarse filtration after preparing, it is filled in agitator tank, adds schmigel, calcium carbonate, lime white, sodium bentonite, nanometer scale ceramics powder while stirring; Prepare suspension mixed solution;

2) suspension mixed solution above-mentioned steps obtained mixes with other remaining ingredients, and the heating that stirs, to 120-160 DEG C, is incubated 3-4 hour, stove is cooled to 60 DEG C, is incubated 1-2 hour, is again heated to 100-120 DEG C, it is incubated 1 hour, is cooled to room temperature with 10 DEG C/h, namely prepare finished product coating.

Compared with prior art, there is advantages that

Coating of the present invention is coated on cement based exterior wall, and cohesive force is strong, is not easily cracked and comes off, and to acidproof, alkaline-resisting, fire-resistant, water resistance is good.

Detailed description of the invention

The building coating that a kind of cementability is good, is made up of following component with parts by weight: calcium carbonate 35-45 part, lime white 30-40 part, waterglass 4-7 part, schmigel 10-12 part, sodium bentonite 6-10 part, suspending agent 4-6 part, lignin sulfonic acid 1-2 part, ethyl acetate 2-4 part, sodium borate 2-4 part, water-soluble urea-formaldehyde resin glue 5-7 part, nanometer scale ceramics powder 1-2 part, water 85-100 part, concrete preparation process is as follows:

1) waterglass and water-soluble urea-formaldehyde resin glue are mixed in proportion, and add water by water inventory 10%-20%, dissolve for liquid with standby at high temperature 80 DEG C-90 DEG C, glue carries out coarse filtration after preparing, it is filled in agitator tank, adds schmigel, calcium carbonate, lime white, sodium bentonite, nanometer scale ceramics powder while stirring; Prepare suspension mixed solution;

2) suspension mixed solution above-mentioned steps obtained mixes with other remaining ingredients, and the heating that stirs, to 120-160 DEG C, is incubated 3-4 hour, stove is cooled to 60 DEG C, is incubated 1-2 hour, is again heated to 100-120 DEG C, it is incubated 1 hour, is cooled to room temperature with 10 DEG C/h, namely prepare finished product coating.
