Abstract
The invention relates to a polyvinyl acetate building coating which is prepared from the following raw materials in parts by weight: 100 parts of polyvinyl acetate emulsion, 1 to 3 parts of hydroxypropyl methyl cellulose, 5 to 15 parts of acetate fibers, 8 to 10 parts of methyl alcohol, 1 to 10 parts of silicone oil, 2 to 6 parts of paraffin, 60 to 80 parts of deionized water, 10 to 15 parts of propylene glycol monomethyl ether, 10 to 20 parts of defoaming agent, 30 to 40 parts of dichloromethane, 15 to 25 parts of ethylene glycol, 15 to 25 parts of sodium hydroxide, 4 to 8 parts of plasticizer, 15 to 35 parts of lime, 2 to 8 parts of tributyl phosphate and 10 to 30 parts of xylene. The viscosity of the building coating is between 45s and 55s; the bonding strength of the building coating is between 30MPa and 40 MPa; the surface of the building coating is dried within 20 to 40 minutes; and the building coating is completely dried within 18 to 20 hours. The building coating cannot be blistered and desquamated after being soaked in water for 20 to 30 days. A coating film is resistant to scrubbing, namely, the coating film can be scrubbed for 2800 to 3000 times. Thus, the building coating can be widely produced and continuously used for replacing the existing material.
Description
Technical field
The application belongs to paint field, relates in particular to a kind of Vinyl Acetate Copolymer building coating.
Background technology
Coating, in China, tradition name is called paint.So-called coating is to be coated in protected or decorated body surface; and can form with coated article the continuous film of firm attachment; normally taking resin oil or emulsion as main; add or do not add defoamer, filler; add corresponding additive, with organic solvent or the formulated thick liquid of silicone oil.China's coating circle more authoritative " coating process " book is definition like this: " coating is a kind of material, and this material can be coated in article surface by different construction technologies, forms and adheres to firmly, has some strength, continuous solid film.The film common name film forming like this, claims again paint film or coating." paint finishing can and form the material of complete and tough and tensile protective membrane with the fine bonding of body material in body surface, is called coating.Coating and paint are identical concepts.Paint is people's custom titles used for a long time, introduces after China, just utilizes in building trade always.The effect of coating may be summarized to be three aspects: provide protection, decoration function, specific function effect.The general composition of coating: comprise filmogen, color stuffing, solvent, auxiliary agent.
Coating refers to the general name that is applied to body surface and can form the material of tough and tensile protective membrane, and building coating is an important class in coating, in China, generally will be used for inner wall of building, exterior wall, and ceiling, ground, the coating of toilet is called building coating.Building coating has decoration functions, defencive function and livability and improves function.The shared proportion of various functions is not quite similar because application target is different.Decoration functions is the function of beautifying the appearance value that improves it by buildings.Mainly comprise the design design of plane color, pattern and gloss aspect and the design of three-dimensional pattern design.But to match with the size and shape of the moulding of buildings itself and base material itself, just can fully play out.Defencive function refers to that protection buildings is not subject to the impact of environment and the function of destruction.The content that different types of protected body requires defencive function is also different.As indoor and outdoor application require the index difference that reaches just very large.
Building coating is mainly used in the coating products of house decoration as a class, its market development and real estate industry's development are closely related.Since " the tightest policy of real estate in history " put into effect, market of real estate development is absorbed in low ebb, and since especially entering 2012, the policy of expection is loosening before does not occur, is that firmly the portion of building clearly represents that in the short period of time, policy of regulation and control can not change on the contrary.Some buildingss to mildew-resistant, fire prevention, heat insulating, corrosion-resistant etc. have a particular requirement.It is mainly for indoor application that livability is improved function, contributes to exactly to improve the function of living environment, as sound-proofing, sound absorbing, antisweat etc.And universal along with humanity concept, and the formation of novel harmonious society, designs that a kind of viscosity is high, the Vinyl Acetate Copolymer building coating of fast drying, water tolerance and resistance to wiping excellence is very important.
