Background technology
In general, interior wall coating is after having plastered.After wall puzzles, carry out render and set, when second, basal plane can be put down substantially.Because the requirement of interior wall is higher than exterior wall, so higher to the requirement meeting of planeness, so generally all can criticize putty, the effect of putty is to make metope more smooth.Generally, putty can be criticized Liang Zhi tri-roads.First bottoming, uses the slightly putty of a bit, and second starts levelling, can use choice refreshments.Whether San road depending on circumstances will be criticized.Every batch of one putty all should be polished, particularly together last.After polishing is good, remove floating dust, start priming, after priming paint parches, go up again twice finish paint.
Visible, after construction work indoor wall plaster, often need putty levelling and coating ornamental surface, to reach effect attractive in appearance, that decorate, and realize the functions such as moistureproof.Wall decoration workload in fitting-out work is large, occupies fitting-out work cost ratio large, and labor strength is large, significant to decoration company.
The constructional method of coating generally has brush, rolls, sprays, criticizes four kinds.Brush is material-saving, but more time-consuming.The effect everyway rolling is the comparison golden mean of the Confucian school, is not material-saving, neither effect best, but comparatively speaking, this is the form of construction work that cost performance is higher.The effect of spray is relatively good, but not too easily repairs.The effect of criticizing is best, but takes material most.Spraying is by spray gun or dish formula spraying gun, by means of pressure or centrifugal force, is dispersed into even and fine droplet, is applied over the coating process on coated article surface.Spraying operation production efficiency is high, is applicable to handwork and industrial automation and produces.With respect to other constructional methods, can save a large amount of manually, and speed up the work, and can ensure the quality of products, but spraying there is higher requirement to coating.
Chinese invention patent 200510057418.7 discloses a kind of sprayed coating of imitative stone material.This coating is made up of base-material, auxiliary material, caking agent, surperficial paint vehicle, the consisting of of each component (being weight part below) base-material: jade powder+putty powder; Wherein jade powder 80~120 orders, 8~35 parts; Putty powder 200 orders, 45~60 parts; Auxiliary material: whitening agent and thickening material; 0.1~0.5 part, whitening agent; 0.2~0.6 part of thickening material; Caking agent: glue+Mierocrystalline cellulose+water soluble acrylic acid; Wherein 7~25 parts, glue; 0.3~10 part of Mierocrystalline cellulose; 1.0~7 parts of water soluble acrylic acids.The hardness of this coating and marble, granite are suitable, and have certain toughness, have beautiful decoration for exterior wall, do not come off, ftracture, and soak indeformable, nontoxic advantage.This sprayed coating is mainly used for preparing the material of imitative stone material, and its decorative effect is mainly the effect that represents stone material, not for replacing putty and decorative paint.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of spraying rubber cement that can direct spraying, can directly with gunite machine, pulp spraying be coated on plaster metope, make metope there is stereoscopic sensation, colored beautiful, economic technology simple, without coating, good decorating effect, whole synthesis performance is good.
The object of the invention is achieved through the following technical solutions:
Spraying rubber cement for a kind of finishing, by mass percentage, its composition of raw materials is as follows:
A, Mierocrystalline cellulose 3-5%
B, water 40-50%
C, glycerol 1-2%
D, whiteruss 1-3%
E, halogen calcium phosphate fluoressent powder 1-3%
F, emulsion 5-10%
G, nanometer grade calcium carbonate powder 8-15%
H, water glass 25-40%
Described emulsion is aqueous acrylic emulsion or benzene emulsion.
For further realizing the object of the invention, the consumption of described water glass is preferably 30-35%.
The consumption of described silicone modified styrene-acrylate emulsion is preferably 6-8%.
Described aqueous acrylic emulsion is preferably 996AD or BLJ-998AD; Described benzene emulsion is preferably A-62,3099 or BLJ-816 benzene emulsion.
The median size of described nanometer grade calcium carbonate powder is preferably 60-70nm.
Described Mierocrystalline cellulose is selected Mierocrystalline cellulose or the methylcellulose gum (MC) of sodium carboxymethyl-cellulose (CMC).
The preparation method of spraying rubber cement for described finishing, comprises the steps:
(1) take Mierocrystalline cellulose, glycerol, water glass and water by formula, mix, react at normal temperatures 20-30 hour;
(2) take whiteruss, halogen calcium phosphate fluoressent powder, silicone modified styrene-acrylate emulsion and nanometer grade calcium carbonate powder by formula, mix;
(3) step (2) gained mixture is added in step (1) products therefrom and mixed under agitation condition.
Described aqueous acrylic emulsion is selected Acrylic Ester Emulsion Modified by Organ ic-siloxanes; In organic-silane-modified acrylic ester (organic siloxane modified acrylic acid emulsion) macromolecular chain on Siliciumatom connect alkyl and be subject to after thermooxidizing, what generate is highly cross-linked more stable Si-O-Si key, can prevent its main chain break degraded, and Si-O-Si bond energy and ground tight bond, improve carbonaceous layer and the ground sticking power in the time of high temperature, therefore can effectively improve the easy deciduous of carbonaceous layer.Aqueous acrylic emulsion can be selected the 996AD of the rich Industrial Co., Ltd. of Ahmedabad, the BLJ-998AD of Shanghai Bao Lijia Chemical Co., Ltd..
Benzene emulsion is selected the Shanghai BLJ-816 of Bao Lijia Chemical Co., Ltd. benzene emulsion, the Shanghai A-62 of Zhen Zhou chemistry painting industry company limited benzene emulsion, the federal Chemical Co., Ltd. in Nantong 3099 benzene emulsions; The federal Chemical Co., Ltd. in Nantong 3099 benzene emulsions have excellent water tolerance, scrub resistance, anti-stain characteristic compared with common phenylpropyl alcohol.There is good color developing and tint retention and levelling brushing property preferably with the exterior coating that these product are made.
With respect to prior art, tool of the present invention has the following advantages and beneficial effect:
(1) the present invention is directly coated in pulp spraying in plaster aspect and (does not re-use coating) with gunite machine, makes surface have stereoscopic sensation and good decorative effect.
(2) product of the present invention detects according to state quality standard, and all test items are qualified.
