Abstract
The invention discloses an environmentally friendly waterproof coating and its preparation method. The coating comprises 31-34 parts by weight of asphalt, 8-15 parts by weight of SBS thermoplastic rubber, 6-10 parts by weight of bentonite, 33-40 parts by weight of water, 3-5 parts by weight of an emulsifier, and 0.3-0.7 part by weight of polyacrylate. The coating of the invention can effectively resist base cracking, prevent water-proof membrane fracturing, and can be firmly adhered to the base surfaces of different materials so as to prevent water from flowing under the membrane. The water-proof membrane cured by the waterproof paint of the invention is free of bubbling, sliding, flowing and dripping phenomena after 6h of heating at a temperature of 88DEG C. Raw materials employed by the coating in the invention are all nontoxic and nonvolatile products. Especially, employment of polyacrylate to replace melamine as an acidity and alkalinity adjusting agent mixture in the present market can effectively improve the waterproofness, elasticity as well as aging resistance of the waterproof coating.
Description
Technical field
The invention belongs to chemical field, be specifically related to a kind of environment-friendly type waterproof paint.
Background technology
At present, domestic existing modifying asphalt coating is take petroleum pitch as base-material, take SBS rubber as properties-correcting agent, and take natural nano-material as filler, and the aqueous waterproofing paint that produces of auxiliary high molecular polymer.The requirement less than waterproof and environmental protection that not only cost is high, solid content is low but also the finished product indices reaches of this coating, the present invention propose a kind of new efficient and environment-friendly type waterproof paint under above background, make it have higher solid content, have also reduced production cost simultaneously.Have the advantages such as simple to operate, good water-proof effect.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point and propose a kind of environment-friendly type waterproof paint, make it have simultaneously that solid content is high, Environmental Safety is good, production cost is low and water resistance is good, is a kind of novel environment-friendly waterproof paint and preparation method thereof.
Another object of the present invention is to provide the preparation method of above-mentioned environment-friendly type waterproof paint.
The objective of the invention is to realize in the following manner:
A kind of environment-friendly type waterproof paint, it is characterized in that this coating is comprised of the component of following weight part: pitch 31～34 weight parts, SBS thermoplastic elastomer 8～15 weight parts, wilkinite 6～10 weight parts, water 33～40 weight parts, emulsifying agent 3～5 weight parts, polyacrylic ester 0.3～0.7 weight part.
Described pitch is 97
#Heavy traffic paving asphalt, emulsifying agent are preferably the mixture of sodium lauryl sulphate and polyethers.Described wilkinite is sodium bentonite.
The preparation method of above-mentioned environment-friendly type waterproof paint comprises the following steps:
1) add the SBS thermoplastic elastomer in pitch, then add the aromatic oil of pitch weight 16～22%, when being heated to 170 ℃, grind with colloidal mill, till reaching complete Uniform Dispersion, then be cooled to 120 ℃～130 ℃, standby;
2) Xiang Shuizhong adds wilkinite, warming while stirring to 60 ℃～80 ℃, then add emulsifying agent and polyacrylic acid ester mixture, standby;
3) with step 1) and step 2) two kinds of prepared composition emulsifications;
4) to step 3) add the styrene-butadiene latex of pitch weight 12～18% in the composition of gained, stir cooling and makes finished product coating.
Step 1) described aromatic oil is preferably furfural extract oil, step 3) preferably adopt the level Four pipeline-type emulsifying machine to carry out emulsification.
The present invention is by new technical recipe and new preparation technology; make rubber molecule and pitch fused being integrated fully; can form rapidly the seamless black waterproof coating of snappiness that one deck has rubber performance after solidifying, firmly cohere on basal plane, produce for permanent effectively waterproofing protection.
Beneficial effect of the present invention compared with the prior art:
The present invention has＞850% extension property, effectively resist basic crack, and prevent the waterproof membrane fracture; Cohesive strength can reach 2.55Mpa, can stick to securely on the basal plane of different material, can prevent effectively that moisture is in the film current downflow.Waterproof membrane after waterproof paint of the present invention solidifies heats 6 hours without foaming, slip, trickling and drip phenomenon at 88 ℃.The solid content of waterproof paint of the present invention can be up to 60～80%, and the starting material that use are nontoxic non-volatile product, and the emulsifying agent that adopts is nontoxic anionic emulsifier; The present invention is take water as solvent, and is nontoxic, do not contain inflammable gas, do not endanger workers ' health and site safety, so product does not produce any pollution to atmosphere, underground water after using.Simultaneously whole technique building-up reactions is gentle, there is no High Temperature High Pressure, effectively reduces energy consumption.The present invention need not dilute, and can directly brush; Also can construct at moist basal plane (without open fire), applied widely, can construct in 0 ℃～60 ℃ scopes.The SBS modifying asphalt composition that the present invention is exclusive, fully compatible with asphalt water-proof coiled material; Water composition makes the cement mortar layer of itself and water-based can be fine fused.Particularly substituting by polyacrylic ester the trimerization chloramines of using on the existing market can effectively increase water-repellancy and the elasticity of waterproof paint as the acid-alkali accommodation agent composition, and increases the ageing resistance of coating.
