Abstract
The invention belongs to the technical field of novel waterproof materials and particularly relates to a one-component polyurethane waterproof coating which comprises the following components in parts by weight: 40-60 parts of polyether, 25-35 parts of asphalt, 5-10 parts of diisocyanate and 20-40 parts of auxiliaries, wherein the auxiliaries include a solubilizer, stone powder and low-viscosity oil. The one-component polyurethane waterproof coating provided by the invention has good high- and low-temperature resistance and acid-base resistance; the construction is convenient and quick, and preparation is not needed for cold construction; and the bonding property with various building materials is good.
Description
Technical field
The invention belongs to waterproof material technical field, especially relate to a kind of monocomponent polyurethane waterproof
Coating.
Background technology
In recent years, China is more and more higher to the requirement of roofing or underground waterproof engineering, and existing double-component
Water-repellent paint find in long-term working practice its come with some shortcomings part, one, construction time requirement
Weigh A, then the dispensing of B component carries out strong stirring, being easily used to of volatile solvent therein
Cause fire, the most unfavorable to environmental conservation；Two, mixed coating needs after configuring to be finished as early as possible,
If preparation excess also can only slattern；Three, its high-low temperature resistant, acid-proof alkaline are not ideal enough.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, it is provided that a kind of high-low temperature resistant, acid-proof alkaline are preferable, nothing
Must prepare, convenient and quick construction, the monocomponent polyurethane all having bonds well performance with various building materials is waterproof
Coating.
One single-component polyurethane water-proof paint of the present invention, including polyethers, Colophonium, diisocyanate with help
Agent, the weight portion of said components is:
Described auxiliary agent includes solubilizing agent, stone powder, light viscosity oil.
Described Colophonium is asphalt.
Described solubilizing agent, stone powder, the ratio of light viscosity oil are 2: 5: 1.
Described stone powder is mica powder, Pulvis Talci or calcium powder.
Advantages of the present invention and good effect be: the present invention is the diisocyanate with macromolecule, divides greatly
The base polyurethane prepolymer for use as of the polyethers synthesis of son amount and Colophonium are as material of main part, by adding solubilizing agent, stone
The auxiliary agents such as powder, low viscosity oils and a kind of single-component waterproof coating material of synthesizing；Polymer substance therein divides
Son amount is relatively big, and viscosity is the biggest, and therefore the weight ratio of polyethers and diisocyanate to control not less than 4
Degree, in order to suppression chain extending reaction；The light viscosity oil wherein added has the effect of dilution, nontoxic nothing
Taste is non-volatile, can be dispersed stably in polyurethane asphalt system and not separate out, and can be preferable
Infiltration waterproof matrix to ensure adhesive property；Owing to asphalt and polyurethane are that two kinds of polarity are different
Polymer substance, for ensureing that product is stablized not stratified during storing, makes in the way of mixing solubilisation aids
Asphalt and polyurethane both materials mix homogeneous purpose macroscopically reaching；Product is in storage period
Between the solid powder sedimentation phenomenon that occurs need to be solved by admixture stone powder, the absorbable part of stone powder
Oily matter, and suspend wherein, make material entirety retrogradation but do not increase viscosity, thus be effectively prevented
Powder settles, it is ensured that the operability of product construction.The present invention has good high-low temperature resistant, acid and alkali-resistance
Performance；Convenient and quick construction, cold construction need not be prepared, and has good adhesive property with various building materials.
