Abstract
The invention relates to a micro-bubble elastic polyurethane waterproof coating. The micro-bubble elastic polyurethane waterproof coating is characterized by comprising the following ingredients in parts by weight: 60-100 parts of polyurethane, 10-20 parts of isocyanate, 10-20 parts of water, 10-20 parts of zinc oxide, 0.1-1.0 part of talcum powder, 0.1-1.0 part of surfactant, 0.1-1.0 part of catalyst, 1-10 parts of hydroxypropyl methylcellulose, 80-100 parts of packing and 10-20 parts of plasticizer; the packing is any one of calcium carbonate, talcum powder and silicon dioxide; the plasticizer is any one of paraffin wax, castor oil, bisphthalate and stearic acid; the catalyst is methyldiethanolamine; and the surfactant is an anionic surfactant. The micro-bubble elastic polyurethane waterproof coating provided by the invention is safe and environment friendly because the organic solvent is adopted; and the coating has the advantages of easiness for coating and drying, good film forming property and smoothness.
Description
Technical field
The present invention relates to polyacrylate coating agent, belong to the textile chemistry field.
Background technology
The esters of acrylic acid coating-forming agent because good combination property is cheap, is one of the most general coating-forming agent; The organic solvent type coating-forming agent is the toluene solution of polyacrylic ester, good film-forming property, epithelium smooth pliable; Be easy to oven dry, but owing to contain 80% toluene solvant, inflammable, explosive, contaminate environment.
Summary of the invention
Technical problem to be solved by this invention provides a kind of microvesicle elastic polyurethane waterproof paint.
For solving the problems of the technologies described above, the present invention realizes like this
The microvesicle elastic polyurethane waterproof paint comprises the following component in weight part:
Urethane 60-100
Isocyanic ester 10-20
Water 10-20
Zinc oxide 10-20
Talcum powder 0.1-1.0
Tensio-active agent 0.1-1.0
Catalyzer 0.1-1.0
Hypromellose 1-10
Filler 80-100
Softening agent 10-20
Described filler is any of lime carbonate, talcum powder, silicon-dioxide.
Described softening agent is any of paraffin, Viscotrol C, Bisphthalate, Triple Pressed Stearic Acid.
The methyldiethanolamine of described catalyzer.
Described tensio-active agent is an AS.
The present invention has following positive effect:
Filler can increase the thickness of coating; Regulate rheological property, improve physical strength, put forward the weather resistance of coating and reduce cost; The filler that the present invention adopts mainly contains: 1, lime carbonate, talcum powder can improve the soft and moist type of coated membrane, reduce water-permeable, the internal stress when eliminating paint solidification; 2, silicon-dioxide can improve the mechanical property of coated membrane, plays effects such as thickening, thixotroping, sag prevention.
Softening agent can reduce the second-order transition temperature of resin, improves toughness, elongation, perviousness and the sticking power of coating.
The microvesicle elastic polyurethane waterproof paint of the present invention's preparation is amber viscous fluid, and solid content is 20%, and viscosity is 5000mPa.s (room temperature).Not not with an organic solvent, safety, environmental protection, its coating is easy to coating, good film-forming property, smooth, is easy to oven dry.
