Abstract
The invention discloses an anti-sagging polyurethane waterproof coating comprising the following components in parts by weight: 20-25 parts of polyether glycol, 5-10 parts of isocyanate, 10-15 parts of a plasticizer, 18-20 parts of light calcium, 20-25 parts of heavy calcium, 0.5-1 part of a thixotropic agent and 0.5-1 part of a latent curing agent. The invention aims at providing the anti-sagging polyurethane waterproof coating suitable for vertical surfaces and slope surfaces, uniform in film formation and good in waterproof effect.
Description
Technical field
the present invention relates to a kind of sag prevention polyurethane water-proof paint, particularly a kind of sag prevention polyurethane water-proof paint of single-component.
Background technology
some domestic at present heavy constructions, as the south water to north, large-scale system venue vault metope, high ferro, subway, tunnel, people's air defense etc., need to carry out waterproof construction at facade or slope.Owing to being facade or slope etc., make construction inconvenient, and easy mass problem.Can be formed without seam waterproof layer with waterproof paint, but with universal coating application on facade or slope time can trickle, cause that top is thin, bottom is thick.Thickness can not scraped in top, and the surperficial became uneven of film.To the thick film of brushing 1.5mm, may need brushing four or five times, significant wastage artificial and engineering time.Therefore the polyurethane water-proof paint developing a kind of anti-sag that can be applied on facade or slope will meet market and customer need, have wide market outlook.At present, to the sag prevention polyurethane water-proof paint for facade or slope, there is larger demand.But, market is not almost suitable for the sag prevention polyurethane water-proof paint on facade or slope.Both made similar research, but also do not introduced to the market widely.
polyurethane water-proof paint, along with developing in recent years, at formula, is produced and is equipped and obtain large increase in production technique.But really there are some more formidable problems in stability in storage and construction and application technique.Stability in storage aspect, can react owing to producing now most urethane remaining-NCO chance water, after wrapping process and packing and storing, as long as have the steam of denier to enter will produce chemical reaction, skinning can be produced at the upper surface of coating, cause dope viscosity to increase, there will be severe slight solidification, cause subsequent construction to be not easily coated with and scrape.For the problem that dope viscosity is large, also take some measures at present, as a certain amount of solvent can be added at recipe, dope viscosity is diminished.And diminishing and the rising of solvent ratios of dope viscosity, the flowing property of coating is increased.When the construction of facade and slope, because self gravitation makes coating that stream pendant occur before not having film forming, be difficult to form the uniform film of thickness, finally cause waterproof effect not satisfactory.
Summary of the invention
for the problems referred to above, the object of this invention is to provide a kind of sag prevention polyurethane water-proof paint being suitable for facade and slope, its film forming evenly, good water-proof effect.
for solving the problems of the technologies described above, the technical solution used in the present invention is:
a kind of sag prevention polyurethane water-proof paint, is characterized in that, comprise following composition:
polyether glycol 20 ~ 25 weight part;
isocyanic ester 5 ~ 10 weight part;
softening agent 10 ~ 15 weight part;
fine particle calcium carbonate 18 ~ 20 weight part;
coarse whiting 20 ~ 25 weight part;
thixotropic agent 0.5 ~ 1 weight part;
latent curing agent 0.5 ~ 1 weight part.
preferably, catalyzer 0.1 ~ 0.2 weight part is also comprised.
preferably, defoamer 0.01 ~ 0.05 weight part is also comprised.
preferably, solvent oil 3 ~ 8 weight part is also comprised.
preferably, described thixotropic agent is aerosil.
preferably, described latent curing agent is ALT-401.
preferably, described polyether glycol is polyethers 330N, chooses any one kind of them in polyethers 2000, polyethers 3050 or several.
preferably, described isocyanic ester is one or both in diphenylmethanediisocyanate, tolylene diisocyanate.
the present invention adopts above technical scheme, tool has the following advantages compared to existing technology: solve the trickling of generation when polyurethane water-proof paint is constructed on facade and slope, flowing down problems, its film forming is even, good water-proof effect, also solve polyurethane coating and viscosity can become large problem containing a small amount of solvent, and stable storing.
