Abstract
The said single-component waterproof coating consists of intermingled rubber of chloroprene rubber, butadiene-styrene rubber and butadiene rubber, petroleum pitch, and assistant. It has outstanding low-temp. flexibility, and it has its property superior to available chloroprene rubber modified pitch coating. It is suitable for use in very cold area.
Description
The present invention relates to the solvent-type waterproofing paint of building material field.
The construction work waterproof paint is by traditional simple pitch base material, gradually to polymer-modified asphalt or high molecular water-proof paint development.As the emulsion modified pitch of water-latex type positively charged ion neoprene of emulsified bitumen modified water-proof coating, the mineral rubber waterproof paint of solvent-borne type chloroprene rubber modifying asphalt and various polymer modifications etc.At present on using, the kind that has a large capacity and a wide range still belongs to the waterproof paint of modifying asphalt.This type of waterproof paint good heat resistance has certain winter hardiness, has cold construction, and is easy to operate, the characteristics of safety non-toxic, and cost is lower, therefore, is applicable to that the common buildings engineering of common climatope is used.But because its anti-fragility, watertightness, especially low-temperature pliability, still undesirable (10 ℃～20 ℃) are being lower than under-20 ℃ the climatope, embrittlement, seepage can occur and do not reach good waterproof effect, therefore are not suitable for high plug area and use.Silicon rubber waterproof coating, though its splitting resistance and low-temperature pliability are all better, current production rate is few, production cost is very high, only uses in the special construction work of minority, can't adapt to the heavy demand of common building engineering.
Purpose of the present invention, for overcoming in the prior art, the shortcoming that a large amount of waterproof paints that use exist on the common building engineering, a kind of have good low-temperature pliability energy and better over-all properties are provided, and the waterproof paint with practical extending application value is to satisfy the needs of extremely frigid zones (as Northeast China, North China) common building engineering waterproofing coating.
The present invention is on the basis of a large amount of experiments, the blended rubber of having selected for use a kind of second-order transition temperature lower (being lower than-45 ℃) brittleness temperature not to be higher than-40 ℃ is a base-material, with petroleum pitch is that auxiliary agents such as filler and vulcanizing agent, anti-aging agent, antifreezing agent, stablizer are the solvent-borne type rubber water-proof paint that raw material is formed, be characterized at extremely frigid zones, water-proof coating still keeps water-proof functions such as the original extensibility of rubber, thereby can improve the ability of surviving the winter and the useful life of water-proof coating.The characteristics of waterproof paint of the present invention are, contain blended rubber 12.8-18.2% in its composition (weight), petroleum pitch 10.5-15.3%, and the composition of described blended rubber (weight) is: chloroprene rubber 60%, styrene-butadiene rubber(SBR) 20%, cis-1,4-polybutadiene rubber 20%.Better consisting of of waterproof paint of the present invention: (weight %)

Waterproof paint of the present invention is realized by following process steps:
(1) blended rubber plasticates and dissolve the blend of successively chloroprene rubber, styrene-butadiene rubber(SBR), cis-1,4-polybutadiene rubber being plasticated on twin-screw extruder, it is mixing evenly to add stearic acid, magnesium oxide, antifreezing agent, scorch retarder, talcum powder, anti-aging agent, add zinc oxide, sulphur, the mixing thin-pass of promotor again, to the 1-2mm thin slice, following sheet, cooling; With blended rubber section, the dissolving of having plasticated;
(2) dissolving of petroleum pitch is with the petroleum pitch heat fused, and dehydration after the cooling, adds dissolution with solvents;
(3) dissolved blended rubber (1) mixes in change-can mixer with petroleum pitch (2) and ethanol, stirs and promptly makes the waterproof paint product that can spray or brush or scrape.
The raw material of forming waterproof paint of the present invention is described as follows: the chloroprene rubber of selecting for use is homemade LDZ-320 type, and styrene-butadiene rubber(SBR) is homemade DBT-3011 type, and cis-1,4-polybutadiene rubber is homemade DZ-9000 type; Petroleum pitch be+No. 10 ,+No. 30 ,+No. 60 ,+No. 100 petroleum pitch in any; Antifreezing agent can be that butyl oleate, scorch retarder can be sodium-acetates, and other raw material is the technical grade commodity.Selected solvent can be any in the mixed solvent of benzene,toluene,xylene, 1: 2 benzene and dimethylbenzene, 1: 1 benzene and vinyl acetic monomer, 1: 1: 1 benzene and toluene and dimethylbenzene.
The type of anti-plug rubber water-proof paint outward appearance of the present invention is memnonious thick liquid, and total solid content is 30-40%, its main performance index such as table 1.Its cold-resistant over-all properties that reaches substantially exceeds existing solvent-borne type chloroprene rubber asphalt waterproofing coating and positively charged ion neoprene asphalt waterproofing paint, and wherein some performance index approaches silicon rubber waterproof coating substantially.Therefore the cold tolerance of waterproof paint of the present invention can satisfy the needs of extremely frigid zones (as Northeast China, North China extremely frigid zones).Its cost has actual application value well below silicon rubber waterproof coating.Waterproof paint of the present invention in addition is a single component, have cold construction, advantages of simple operation, can brush for twice or three times, and can reach the rubber coiled material thickness requirement, but better than rubber coiled material water tight integrity, can remove rubber lock sticking construction from, even the omission point is arranged, it is also very convenient to repair, and therefore has the two-fold advantage of rubber coating and rubber coiled material.Because its winter hardiness is outstanding, construction is not subjected to seasonal temperature to change restriction.Waterproof paint of the present invention is applicable to water storage project waterproof paints such as construction work indoor and outdoor and vault, swimming pool; Also can promote and be used for bridge, contain the waterproofing work of swimming.
