Description

A kind of water based paint

Technical field

The application belongs to paint field, particularly relates to a kind of water based paint.

Background technology

Coating, at the entitled paint of Chinese tradition.So-called coating is to be coated in be protected or filled The body surface of decorations, and can be with the continuous film of coated article formation firm attachment, it is common that with tree Fat or oil or emulsion are main, add or without drier, filler, add corresponding additive, With the formulated thick liquid of organic solvent or M-phthalic acid.China's coating circle is more authoritative " coating process " book be defined such that " coating is a kind of material, and this material can To be coated in object surface by different construction technologies, formed adhere to firmly, have some strength, Continuous print solid film.The film common name film so formed, also known as paint film or coating." coating Cover with paint, lacquer, colour wash, etc. and can very well bond with matrix material in body surface and form complete and tough and tensile protecting film Material, referred to as coating.Coating and paint are the identicals concept.Paint is people's habits used for a long time Used title, after introducing China, utilizes in building trade the most always.The effect of coating can be general Including is three aspects: protective effect, decoration function, specific function effect.General group of coating Become: comprise film forming matter, drier, solvent, auxiliary agent.Coating refers to be applied to body surface And the general name of the material of tough and tensile protecting film can be formed, building coating is an important class in coating Not, in China, inner wall of building typically will be used for, exterior wall, ceiling, ground, toilet Coating is referred to as building coating.

When the color produced due to dyeing when using different timber to carry out grinding and buffing Change and change compared with using and will make moderate progress produced by coatings volatile organic compounds.For relatively soft timber Kind is when polishing, it is preferred to use the abrasive of 280 sand.Hard textured timber may Need the sand milling material of polishing less than 220 sand.Traditionally, when using coatings volatile organic compounds processing system, The most first use solvent coloring agent as modal surface coloured material.Many water-based colorings Agent can not produce the color effect as solvent-borne type coloring agent.Some water based coloring agent is difficult to should With, and realize unified dyeing color effect.Although, new water based coloring agent is easier to use, But it may when attempting to be transformed into the dyeing recipe of water based coloring agent from solvent-borne type coloring agent It is difficult to match colors completely.And popularizing along with humanity concept, and novel harmonious society The composition of meeting, the water based paint designing a kind of hardness height, fast drying and impact strength high is very Necessary.
