Abstract
The invention provides a kind of slipping agent with the grey calcium base of improvement or cement based inner and external wall putty performance, thus solve that existing putty construction feel is heavy, slow, easily sagging, unit surface putty large usage quantity the shortcoming of construction speed, this putty slipping agent be by components by weight percent be the calcined kaolin of 54 ~ 78%, the hydroxypropyl starch ether of 20 ~ 40% and 2.0 ~ 6.0% polyacrylamide Homogeneous phase mixing make.Putty slipping agent of the present invention, when addition is little, just the construction smoothness of grey calcium base or cement based inner and external wall putty can be increased considerably, also suitably can increase the toughness of putty, make putty have excellent sag resistance, the intensity of the rear putty of sclerosis can also be improved simultaneously and reduce the usage quantity of unit surface putty, both material cost had been saved, also save cost of labor, be a kind of well putty auxiliary agent, be particularly suitable for using in grey calcium base or cement based inner and external wall putty.
Description
Technical field
The present invention relates to a kind of auxiliary agent, particularly relate to a kind of slipping agent contributing to improving buildings external and internal wall putty performance, more specifically relate to and a kind of there is the slipping agent improving grey calcium base or cement based inner and external wall putty performance, reduce unit surface putty usage quantity.
Background technology
Putty is a kind of decorating glue gel material of smooth surface of wall, is a kind of thick slurry coating material, is that coating whitewashes front requisite a kind of product, also can directly as ornament layer.Putty can be coated with to impose on priming paint or be directly coated with and impose on object, in order to remove coated article rugged defect on the surface, both can fill up the working-surface that there is depression local, also can at all surfaces blade coating.The inner wall putty of present main flow on the market, its production formula is: 15 ~ 25% grey calcium, 75 ~ 85% coarse whitings, 0.3 ~ 0.5% ether of cellulose; The production formula of exterior wall putty is: 30 ~ 35% cement, 55 ~ 60% coarse whitings, 10 ~ 20% fine sands, 0.3 ~ 0.5% ether of cellulose, 0.5 ~ 1.5% rubber powder.
As can be seen from above-mentioned formula, ether of cellulose is indispensable material in putty, this is due to putty single construction thinner thickness, generally be about 1 millimeter, and putty is coated on large-area dry body of wall, the water-retaining capacity of body of wall is very strong, and putty must have particularly preferred water-retentivity and toughness to be flattened to be applied in swimmingly on body of wall, and ether of cellulose has effect of thickening water conservation thickening, certain denseness, water-retentivity and cohesiveness can be provided for putty.The viscosity of ether of cellulose from hundreds of to hundreds of thousands of not etc., but the ether of cellulose of not all viscosity is all applicable to putty, when the ether of cellulose selecting viscosity lower, the viscosity of putty is inadequate, the easy sagging of putty or ground of dropping after upper wall, and not only difficulty is constructed and waste material, and viscosity is too low, the water-retentivity of ether of cellulose is also poor, and on putty, after wall, dehydration is too fast, is difficult to construction; And during the ether of cellulose selecting viscosity higher, although water-retentivity and sag resistance better, but putty construction feel is too heavy, smear and require great effort very much, speed of application is comparatively slow, and single construction thickness is too thick, not only increases material usage, too increase labour cost, the viscosity of cellulose ether being relatively applicable to putty use is approximately 7 ten thousand to 10 ten thousand.But, even if by selecting the ether of cellulose of appropriate viscosity range, the putty that performance is suitable for relatively can be obtained, also still cannot solve putty construction feel weight completely, construction speed is slow, easy sagging, the shortcomings such as unit surface putty large usage quantity, therefore, be difficult to grey calcium base or cement based putty to be adjusted to suitable toughness and water-retentivity by ether of cellulose merely, construction feel be light to reach, smooth effect of constructing.For this reason, finding a kind of suitable auxiliary agent, make the viscosity of grey calcium base or cement based putty be easy to regulate, thus improve the workability of putty and reduce the usage quantity of unit surface putty, is those skilled in the art's technical problems in the urgent need to address.
Summary of the invention
For solving above Problems existing, the object of this invention is to provide a kind of putty slipping agent, this slipping agent not only can improve workability, the reduction unit surface putty usage quantity of grey calcium base or cement based inner and external wall putty, and can improve the intensity of the rear putty of sclerosis.
For realizing above object, of the present invention have the slipping agent improving grey calcium base or cement based inner and external wall putty performance, be by components by weight percent be the calcined kaolin of 54 ~ 78%, the hydroxypropyl starch ether of 20 ~ 40% and 2.0 ~ 6.0% polyacrylamide Homogeneous phase mixing make; Calcined kaolin is the calcined kaolin that whiteness is greater than 90%, median size is less than 1 micron, polyacrylamide to be molecular weight be 1500 ~ 2,000 ten thousand anionic polyacrylamide.
The recommendation addition of above-mentioned slipping agent in grey calcium base or cement based inner and external wall putty is the 0.1-0.2% of putty gross weight.
in order to accelerate the dissolution rate of polyacrylamide, reduce the churning time before putty use, above-mentioned polyacrylamide preferred size is the Powdered polyacrylamide of 100-110 object.
The present invention selects that frictional coefficient is very little, layer and interlayer have fine oilness and thixotropic calcined kaolin as base material, coordinate good water solubility and hydroxypropyl starch ether stable under strong basicity environment and there is good flocculence polyacrylamide to prepare putty slipping agent, because the particle diameter of calcined kaolin is little, a small amount of calcined kaolin just can be filled in whole putty material, the frictional force of the friction resistance in putty between various material and putty and spatula is minimized, thus raising operating efficiency, tiny calcined kaolin is filled in the gap of coarse whiting, cement or grey calcium simultaneously, the density of putty can be improved, increase the intensity of putty, and hydroxypropyl starch ether has extraordinary fast thickening ability, low-down addition just can reach effect, the raising putty consistency of fine thickening, improves the sag resistance of putty, polyacrylamide is a kind of water miscible high molecular polymer, can fully dissolve in putty, and the very thin glued membrane of one deck can be formed on each tiny material granule, this glued membrane has extraordinary oilness, the frictional force of various storeroom in putty can be reduced, alleviate the problem that putty construction feel is heavy, polyacrylamide also has certain thickening property, the sag resistance of putty can be improved in putty, in addition, the putty adding polyacrylamide also can form one deck glued membrane on surface of having constructed, this glued membrane can be covered in putty surface after having done, strengthen the intensity on putty surface.
The present invention utilizes above-mentioned three kinds of materials performance characteristics separately and mutual cooperation, and for grey calcium base or cement based inner and external wall putty to the performance requriements of this material, by rational apolegamy, obtain a kind of putty surface slip agent of superior performance, this surface slip agent is when addition is little, just the construction smoothness of grey calcium base or cement based inner and external wall putty can be increased considerably, also the toughness of putty can suitably be increased, make putty have excellent sag resistance, the intensity of the rear putty of sclerosis can also be improved simultaneously; Slipping agent of the present invention can reduce the usage quantity of unit surface putty, has both saved material cost, has also saved cost of labor, is a kind of well auxiliary agent, is particularly suitable for using in grey calcium base or cement based inner and external wall putty.
