Description
Technical field
The present invention relates to a kind of finishing with the spraying rubber cement, particularly relate to a kind of finishing, be mainly used in the construction work internal wall finishing with spraying rubber cement and preparation method thereof.
Background technology
In general, interior wall coating is after the completion of plastering.After wall puzzles, carry out render and set, basal plane can be put down basically in the time of second road.Because the requirement of interior wall is higher than exterior wall, thus to the requirement meeting of planeness than higher, so generally all can criticize putty, the effect of putty is to make metope more smooth.Generally speaking, putty can be criticized two to three roads.First road bottoming, with thick any putty, second road begins levelling, uses choice refreshments.Whether the 3rd road depending on circumstances will be criticized.Every batch of one putty all should be polished, and is particularly together last.After polishing is good, remove floating dust, the beginning priming is gone up the twice finish paint again after priming paint parches.
It is thus clear that, often need putty levelling and coating ornamental surface behind the indoor wall plaster of construction work, with the effect that reaches attractive in appearance, decorates, and realize function such as protection against the tide.Wall decoration workload in fitting-out work is big, and it is big to occupy fitting-out work cost ratio, and labor strength is big, and is significant to decoration company.
The execution of coating method generally has brush, rolls, sprays, criticizes four kinds.Brush is material-saving, but more time-consuming.The effect everyway that rolls is the comparison golden mean of the Confucian school, is not material-saving, and is neither effect best, but comparatively speaking, this is the higher form of construction work of cost performance.The effect of spray is relatively good, but repairs not too easily.The effect of criticizing is best, but takes material most.Spraying is through spray gun or dish formula spraying gun, by means of pressure or cf-, is dispersed into evenly and fine fog, is applied over the coating process on coated article surface.Spraying operation production efficiency is high, is applicable to handwork and industrial automation production.With respect to other constructional methods, can save a large amount of manual works, 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 (following be weight part) base-material: jade powder+putty powder; Jade powder 80～120 orders wherein, 8～35 parts; Putty powder 200 orders, 45～60 parts; Auxiliary material: whitening agent and thickening material; 0.1～0.5 part in whitening agent; 0.2～0.6 part of thickening material; Caking agent: glue+Mierocrystalline cellulose+water soluble acrylic acid; Wherein glue is 7～25 parts; 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 certain toughness is arranged, and being used for exterior wall has beautiful decoration, does not come off, ftractures, and soaks indeformable, nontoxic advantage.This sprayed coating mainly is the material that is used to prepare imitative stone material, and its decorative effect mainly is an effect of representing stone material, is not to be used to replace putty and decorative paint.
Summary of the invention
Technical problem to be solved by this invention provides a kind of spraying rubber cement that can directly spray; Can directly slurry be sprayed on the plaster metope, make metope have stereoscopic sensation with the gunite machine, colored beautiful, economic technology simple, without coating; Good decorating effect, the whole synthesis performance is good.
