Description
Technical field
The present invention relates to polyurethane water-proof paint technical field, be specially a kind of concrete construction engineering solidification mono-component color polyurethane water-proof paint and preparation method thereof of diving.
Background technology
Current domestic polyurethane water-proof paint has single component and two-pack two kinds of forms.
Two-component Waterproof Polyurethane Coating one component is the performed polymer of isocyanic ester and polyvalent alcohol, and another component is the compound of active hydrogen, as: polyether glycol, MOCA etc.During construction, two components are mixed in proportion, brush on waterproof matrix, film-forming, thus play waterproof action.But during Two-component Waterproof Polyurethane Coating construction, carry out on-the-spot proportioning, mixing, troublesome poeration, simultaneously the quality of workmen and skill level also can cause the difference in quality product.And mono-composition poyurethane water-proof paint is produced simple because of it, easy for operation, its demand is increasing.
The subject matter that mono-composition poyurethane water-proof paint exists is that intensity and toughness all link closely GB, if tensile strength is 2.45MPa, elongation at break is 450%, watertightness is that 0.3MPa30min is waterproof, especially toughness is poor, these quality problems that construction party can be caused to cause because of the reason of skill level of constructing, and also limit the range of application of product simultaneously, especially the low-down north of some temperature, the toughness of material more can not meet the requirement of construction; The special dimension higher to water-proof material toughness reguirements at some also has very large restriction.It is high to there is cost in mono-composition poyurethane water-proof paint prior art, poor performance, especially poor with extension property, often just reaches GB, therefore causes because of workmen and mode, construction area is different and cause quality accident.
Determine a lot of because have of waterproof paint intensity and unit elongation, as polyethers and kind and proportioning, the content of isocyanic ester, the kind of solvent, the kind etc. of auxiliary agent, screening process complexity, formulating of recipe difficulty is larger.Because the intensity of mono-composition poyurethane water-proof paint and toughness are conflicting to a certain extent, therefore, the gordian technique of mono-composition poyurethane water-proof paint is under the prerequisite ensureing coating mechanical strength, how to improve the unit elongation of coating, need find the trim point before the two.
Mono-composition poyurethane water-proof paint is mainly divided into two large classes: water cure and latent solidification two kinds, wherein water cure type mono-composition poyurethane water-proof paint need mix with appropriate water when constructing, easily produce bubble when solidifying and cause many pores in film forming matter, thus affect water resistance and the mechanical strength of waterproof layer, simultaneously again due to amount of water number also have considerable influence to waterproof layer performance, thus make waterproof layer cause the performance difference of waterproof layer very large because the skill level of workmen is different; And curing type one-pack polyurethane water-proof paint of diving can avoid above problem, do not need to mix with water when constructing, but react thus film forming by the moisture in air and polyurethane monocomponent waterproof paint, film structure is closely knit, better performances.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of based on isocyanate-terminated performed polymer polymkeric substance, moisture cured latent solidification mono-component color polyurethane water-proof paint and preparation method thereof.This waterproof paint has the advantages such as intensity is high, elongation at break is large, Application Areas is wide, high comprehensive performance, is especially applicable to be out of shape the needs compared with the special dimension such as large regions and low-temperature region waterproof.
