Abstract
One-component self-curing polyurethane waterproof coating is characterized by being formed by preparing the following components by mass percent: 20% to 40 % of polyhydroxy compounds, 10% to 35% of polyisocyanate, 0.1% to 1% of initiating agents, 10% to 30 % of plasticizers, 15% to 30 % of fillers, 0.1% to 1% of anti-ultraviolet agents, 0.2% to 4% of water removal agents, 0.05% to 1% of silane coupling agents and 1% to 3% of antifoaming agents. The one-component self-curing polyurethane waterproof coating has the advantages that a self-curing purpose is achieved through water absorption of isocyanate in polyurethane prepolymer, no curing agent needs to be added additionally, a coating obtained after construction is very thin, and the coating and a substrate have good adhesion, excellent abrasion resistance and corrosion resistance to acid, alkali and other chemicals. No air bubble exists in the coating, and the coating shows good waterproof effect. The one-component self-curing polyurethane waterproof coating overcomes shortcomings of the existing technology, tensile strength of the coating reaches 3 to 22 MPa, breaking elongation of the coating is larger than 150%, and the one-component self-curing polyurethane waterproof coating is suitable for various different environments and can be used for construction directly.
Description
Technical field
The present invention relates to chemistry painting industry waterproof technique field, is a kind of high-performance single-component self-curing polyurethane waterproof paint that is different from double-composition polyurethane waterproof paint.
Background technology
Polyurethane water-proof paint be the sixties in 20th century at a kind of high polymer waterproof material that states such as America and Europe, day grow up, can be divided into double-composition polyurethane waterproof paint and mono-composition poyurethane water-proof paint.Stages such as the tar stage has been experienced in its development, pitch stage are at present just towards the environment-friendly type stage development.
Double-component polyurethane coating requires weigh batching, and in batching, mixes quantitative volatile solvent when construction, carries out brute force then and stirs.The volatilization of the volatile solvent that is added is very unfavorable to environment protection; And be easy to cause fire; Have the high-risk index, not only construct trouble but also exist batching to be forbidden to cause degradation influence waterproof effect of double-composition polyurethane waterproof paint is to the higher requirement of field mix proposition.Said tar polyurethane waterproofing paint in front and pitch type waterproof paint belong to double-composition polyurethane waterproof paint.At present, the domestic polyurethane water-proof paint of China also all is two component solvent-borne type products basically.Along with the raising day by day of environmental requirement, the use of volatile solvent progressively is restricted in chemical building material production and the construction process, therefore is necessary to develop the polyurethane water-proof paint that helps decontamination and easy construction.
And mono-composition poyurethane water-proof paint construction is comparatively easy, need not mix stirring, and tackify not before the brushing has certain advantage.External existing multiple monocomponent polyurethane waterproof paint, its physicals is basic identical with two component products.The monocomponent polyurethane waterproof paint that U.S.'s " wound is high " company produces is exactly one of them.Though existing non-solvent single-component water-proof asphalt-base polyurethane paint has been avoided the problem of dual-component coating construction trouble, owing to be based on the coating of bitumen production, it still constitutes a threat to environment protection.In addition, existing mono-component waterproofing paint leans on moisture curing, and is inner at thick layer, influences waterproof effect thereby be easy to generate bubble.
Summary of the invention
The object of the invention just provides a kind of single-component self-curing polyurethane waterproof paint, is viscous liquid before this coating brushing, and the moisture-curing in the ingress of air of brushing back forms whole anhydrous seam waterproof layer.
The present invention realizes by following scheme.Single-component self-curing polyurethane waterproof paint be with polyol (like, Viscotrol C) synthetic base polyurethane prepolymer for use as as material of main part, a kind of self cure coating that obtains through the admixture subsidiary material.The factors such as consumption, temperature of reaction and reaction times of strict control reactant have less viscosity to be suitable for constructing operation to guarantee the synthetic performed polymer.Wherein self cure is in air, to absorb water to solidify through the isocyano in the base polyurethane prepolymer for use as to realize.
