Description

A kind of solid paint for building construction

Technical field

The application belongs to paint field, particularly relates to a kind of solid paint for building construction.

Background technology

Coating, is called paint in Chinese tradition name. So-called coating is to be coated in protected or decorated body surface; and the continuous film of firm attachment can be formed with coated article; usually based on resin or oily or emulsion; add or without extender pigment, filler; add corresponding additive, with the formulated thick liquid of organic solvent or barium sulfate. Gelatin (Gelatin), is commonly used to make fruit jelly and other dessert, is by the animal bone boiled, skin and what tendon was made. A kind of succedaneum is that agar (Agar-Agar) is made with zostera marina; Another kind of succedaneum is to make with the root of Herba Gelsemii Elegantis. The agar sold generally has the strip of noodles sample, powdery, long bulk, and may often be such that linen. Paint finishing can bond and be formed the material of complete and tough and tensile protecting film very well in body surface with matrix material, is called coating. Coating and paint are the identicals concept. Paint is people's custom titles used for a long time, after introducing China, just utilizes in building trade always. The effect of coating may be summarized to be three aspects: protective effect, decoration function, specific function effect. The general composition of coating: comprise film forming matter, color stuffing, solvent, auxiliary agent.

Coating refers to and is applied to body surface and can form the general name of the material of tough and tensile protecting film, and building coating is an important class in coating, in China, generally will be used for inner wall of building, exterior wall, ceiling, ground, and the coating of toilet is called building coating. Building coating has decoration functions, defencive function and livability and improves function. Proportion shared by various functions is not quite similar because application target is different. Decoration functions is the function beautifying the appearance value improving it by building. Mainly include the concept of plane color, pattern and gloss aspect and the concept of three-dimensional pattern. But to close with the size of the moulding of building itself and base material itself and matching form, just can fully play out. Defencive function refers to the function that protection building is not protected from environmental and destroys. The content that defencive function is required by different types of protected body is also different. The index difference reached as required by indoor and outdoor application is just very big. Building coating is mainly used in the coating products of house decoration as a class, and its market development develops closely related with real estate industry.

Mainly comprising of gelatin forms identical and that molecular weight distribution is very wide peptide molecule mixture for aminoacid, and molecular weight is typically in several ten thousand to tens0000.Gelatin had both had acidity, had again alkalescence, was a kind of amphiprotic substance, and the micelle of gelatin is charged, and under electric field action, it will move to a certain Ghandler motion in the two poles of the earth. Having substantial amounts of hydroxyl in gelatin molecule structure, additionally also have many carboxyls and amino, this makes gelatin have extremely strong hydrophilic. Gelatin does not dissolve in organic solvent, and insoluble in cold water, in cold water, imbibition is to self 5-10 times, being soluble in warm water, be cooled into gel, molten point is between 24-28 DEG C, its dissolubility differs only small with solidification temperature, be subject to moisture content, temperature, the impact of humidity and go bad. Since " in history the tightest policy of real estate " is put into effect, market of real estate development is absorbed in low ebb, and since 2012, intended policy loosens and do not occur before, is that firmly the portion of building explicitly indicates that in the short time, policy of regulation and control will not change on the contrary. Some buildings to mildew-resistant, fire prevention, insulation, corrosion-resistant etc. have particular/special requirement. Livability improves function mainly for indoor application, it is simply that contribute to improving the function of living environment, such as sound-proofing, sound absorption properties, anti-condensation etc. And popularizing along with humanity concept, and the composition of novel harmonious society, the solid paint for building construction designing a kind of viscosity height, stable storing, resistance to water and resistance to wiping excellent is very important.
