The rubber asphalt waterproof coating is high in tensile strength, good in high-temperature resistance and excellent in low-temperature flexibility.
Description
Technical field
The invention belongs to building material technical field, be specifically related to a kind of preparation method of rubber asphalt waterproof coating.
Background technology
Mixed with various rubber in pitch, the shortcoming of the hot mastication of pitch own and low temperature brittleness can be overcome, its tear strength is in the winter time improved, during low temperature-25 DEG C, does not occur crackle; Melt sex change at summer anti-can also be improved, do not soften under high temperature.For this reason, modification to be carried out to petroleum pitch, the demand of construction work and public works could be adapted to.
The method of modifying of pitch has multiple, at present conventional rubber, resin and mineral filler modification, and wherein rubber is the important modification material of pitch.At present, rubber asphalt particle-stabilised to be dispersed in water with small, to form emulsion, i.e. fluid rubber bituminous composition, be widely used the water-tight corrosion-proof at bridge floor, culvert and storage-tank pipeline, it develops a kind of new liquid rubber asphalt waterproofing material faster.This material can carry out cold construction, environment-protecting asepsis, waterproof, anticorrosion, antiseepage, chemical-resistant resistance, and its unit elongation is large, adapts to base course crack distortion, completely can paste with the structural sheet of buildings, adsorbable in aggregate surface.
Fluid rubber bituminous composition, by the classification of chemical structure of molecule, generally can be divided into anionic emulsified rubber asphalt, cationic emulsified rubber asphalt and the several types such as non-ionic type emulsified rubber asphalt and zwitter-ion emulsified rubber asphalt.Cationic emulsified rubber asphalt and anionic emulsified rubber asphalt are in water-proof and anti-corrosive material.Non-ionic type emulsified rubber asphalt with nonionogenic tenside be mainly emulsifying agent rubber non-ionic emulsion to be that the non-ionic type bitumen emulsion of emulsifying agent and corresponding promoter material mix with nonionogenic tenside, its principal feature good stability, thermotolerance and excellent water resistance, cohesiveness is strong simultaneously, wear resistance is high, insensitive to hard water, breakdown of emulsion conjunctiva speed can be controlled, can be used for roof waterproof, underground protection against the tide, pipeline corrosion protection, canal seepage control, bridge deck water-proof etc.Non-ionic type emulsified rubber asphalt is compared with cationic emulsified rubber asphalt, anionic emulsified rubber asphalt, all stablize than cationic emulsified rubber asphalt and anionic emulsified rubber asphalt in acidity, alkaline aqueous solution and hard water, there is low bubble, nontoxic advantage simultaneously.
But, due to the difference of recipe ingredient, aqueous rubber asphalt waterproofing paint there will be various different physicochemical property, current common formula produce the intensity more weak (being less than 0.3MPa) of product, easily peeling off when being subject to larger external force, rupturing, and due to intensity low, there will be sticky tire during construction, destroy the phenomenon such as waterproof layer.Find after deliberation, single emulsifier cannot meet the requirement of High-strength rubber asphalt waterproof paint to emulsified bitumen, because single emulsifier has fixing HLB value, it can not meet HLB scope required for complicated asphalt emulsification.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art and the preparation method that provides a kind of rubber asphalt waterproof coating, gained coating tensile strength is large, and high thermal resistance is good, and low temperature flexibility is excellent.
A preparation method for rubber asphalt waterproof coating, comprises the following steps:
Step 1, with parts by weight, by urethanes 8 ~ 17 parts, acrylic elastomer 10 ~ 22 parts after 70 ~ 80 DEG C of thin-passes are plasticated, add lauric acid amide of ethanol 3 ~ 6 parts, sodium lignosulfonate 2 ~ 5 parts, sulfosuccinate 1 ~ 6 part, 2 ~ 5 parts, Yelkin TTS, mixing, bottom sheet, send into shears, limit sheared edge adds terpolymer EP rubber 2 ~ 4 parts, obtains rubber latex;
