Abstract
The invention discloses an emulsion for a waterproof paint. The emulsion comprises the following components in parts by weight: 8 parts of methyl methacrylate, 15 parts of styrene, 150 parts of 2-ethylhexyl acrylate, 20 parts of butyl acrylate, 4 parts of an active monomer, 3 parts of ethylene unsaturated carboxylic acid, 2.5 parts of a surfactant, 0.08 part of an initiator and 50 parts of water. The invention further discloses a preparation method of the emulsion. According to the invention, a waterborne color-toning rubber paint is prepared from an acrylate emulsion as a film forming matter matched with various pigments and fillers. The dried film can form a continuous coating which has good ductility and breaking strength, is good in acid and alkali resistance, excellent in weather resistance, convenient for construction and free from environmental pollution. The paint used for roof waterproofness is a relatively ideal material.
Description
Technical field
The present invention relates to a kind of water-miscible paint, be specifically related to a kind of emulsion for waterproof paint, the invention still further relates to the preparation method of this emulsion.
Background technology
Along with people are to healthy understanding, more and more recognize the important of environmental protection, coating superior, functionalization, environmental protectionization is also accepted by market gradually, however Coating Market competition is always very fierce, along with the change of consumption structure, function and environmental protection coating material are ready to appear, are the focuses in market; As everyone knows, people 70% time tides over indoor, so the degree of cleaning of room air will directly have influence on people's health.In recent years, along with living standards of the people improve constantly, living environment is constantly improved, when upholstery is increasingly luxurious, attractive in appearance, the problem that affects HUMAN HEALTH because fitting up the indoor pollution causing gets more and more, investigation shows: 68% disease cause is relevant with the pollution of room air, and 80% cancer is relevant with living environment.Therefore, high-efficient and lasting ground purifies indoor harmful gas, the target that keeps life, the Working environment of pure and fresh health to become people more and more urgently to pursue.
Emulsion paint has good film-forming properties, abrasion resistance as coating, its membrane formation mechanism is that filming emulsion is under liquid state, face to be filled into row fully to grind coated, therefore the completely coated filler grain of latex particle, obtain film to become causes its film-forming properties, abrasion resistance, weathering resistance, anticreep mealiness greatly to improve.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, provide that a kind of environmental pollution is little, easy construction and there is a kind of emulsion for waterproof paint of superperformance.
Another object of the present invention is to provide the preparation method of this emulsion.
Above-mentioned purpose of the present invention is achieved by the following scheme:
For an emulsion for waterproof paint, described emulsion comprises the component of following weight part:
Further, a kind of emulsion for waterproof paint, described emulsion comprises the component of following weight part:
A preparation method for the emulsion of waterproof paint, comprises the steps:
Monomer is carried out to suction header tank after pre-emulsification, another header tank of suction after water dissolution for initiator by the amount of formulating of recipe and tensio-active agent and water;
In the mode dripping, enter reactor and carry out polyreaction, temperature of reaction is controlled at 70-85 degree, controls rate of addition, and reaction mass is dripped off at 3-3.5h;
Insulation reaction 1-2h, makes to react completely, then cooling, with ammoniacal liquor, emulsion pH value is adjusted to 7-8.
Compared with prior art, the beneficial effect that the present invention has is:
Compound method of the present invention is simple, and without special equipment, the waterproof paint of preparation is the filmogen coating a kind of water-based color-adjustable, rubber-type that various pigment, filler are made in addition again by acrylate copolymer emulsion.After dried coating film, can form successional coating, coating has good unit elongation and breaking tenacity, acidproof, alkali resistance good, has excellent weather resistance, easy construction, non-environmental-pollution, and as roof waterproof, using is a kind of comparatively ideal material.
