Abstract
The present invention relates to environment protection type single-component nanometer modified waterproof paint of polyurethane, which belongs to waterproof paint of polyurethane. The present invention aims the goals of no coal tar, no solvent of toluene, good performances and low price. The present invention is prepared from 60 to 90 weight portions of polyurethane prepolymer, 30 to 50 weight portions of hydrophilic chain extender, 0.1 to 30 weight portions of additive, 20 to 60 weight portions of filling material, 0.1 to 10 weight portions of nanometer material and 0.05 to 10 weight portions of solidifying agent. The environment protection type single-component nanometer modified waterproof paint of polyurethane can be applied to construction at normal temperature, and is suitable for the water resistance engineering of roofs, underground buildings, ground buildings, etc.
Description
Technical field: the present invention relates to a kind of polyurethane water-proof paint, belong to building coating.
Background technology: existing polyurethane water-proof paint, the problem of the existence that it is general are to contain harmful coal tar and toluene solvant in the coating, and mostly are two component packings greatly, use inconvenient.Along with the day by day raising of people to environmental protection understanding, innoxious to the building coating requirement, also require the use of product to oversimplify more simultaneously.
Summary of the invention: the object of the invention is exactly the deficiency that overcomes above-mentioned prior art, and a kind of coal tar and toluene solvant and performance is good, cost is low environment-protecting nanometer modified waterproof polyurethane paint of not containing is provided.
Coating of the present invention includes base polyurethane prepolymer for use as, hydrophilic chain extender, auxiliary agent, filler, nano material and solidifying agent.The NCO content of base polyurethane prepolymer for use as is 1-20%; Hydrophilic chain extender is a vinylformic acid, and filler adopts lime, cement, flyash, talcum powder, fine particle calcium carbonate etc.; Nano material is the oxide compound of 10-40 nanometer; Solidifying agent is a dibutyl tin laurate; Auxiliary agent is pure and mild ester class.
The coating of the present invention proportioning of unit serving meter by weight is:
Base polyurethane prepolymer for use as 60-90 part, hydrophilic chain extender 30-50 part, auxiliary agent 0.1-30 part, filler 20-60 part, nano material 0.1-10 part, solidifying agent 0.05-10 part.
The method for making of product of the present invention is, hydrophilic chain extender, auxiliary agent, filler, nano material and solidifying agent are mixed, and then, adds base polyurethane prepolymer for use as and mixes.
Product of the present invention is constructed at normal temperatures, is applicable to waterproofing works such as roofing, hypogee, surface structures.The advantage of product of the present invention is: compare with dual-component coating, do not need during use to measure again and be mixed, can directly open and use, use simple, the operating efficiency height.Product cost is low, performance good, and is low to basic unit's water content requirement, can further improve operating efficiency.Adopt nano-material modified after, anti-ultraviolet property, toughness and the intensity of product are greatly improved.
Embodiment:
The coating of the present invention proportioning of unit serving meter by weight is: NCO content is 10% 5 parts of 60 parts of 5 parts of 40 parts in 80 parts of base polyurethane prepolymer for use as, vinylformic acid, propyl carbinols, fine particle calcium carbonates, 10-40 nano zine oxides, 2 parts of dibutyl tin laurates.
The product that is mixed and made into according to the above ratio shows that with the user is on probation its performance reaches JC500 " polyurethane water-proof paint " acceptable end product after tested.
