Propylene lactate buffer solution, it is nontoxic, non-stimulated, it is harmless, meet environmental requirement, the high photopolymer resin of non-film has excellent Different gloss and the transparency, resistance to blocking can be good.
Coarse whiting is exactly calcite in powder, is the abbreviation of powdered whiting, is by natural carbonate mineral such as calcite, Dali Stone, lime stone are ground.It is common powdery inorganic filler, has that chemical purity is high, inertia is big, is not easy to chemically react, heat Stability is good, will not decompose at 400 DEG C or less, whiteness is high, oil absorbency is low, index of refraction is low, matter is soft, it is dry, without the crystallization water, firmly The advantages that spending small low wearing valve, nontoxic, tasteless, odorless, good dispersion.
Mica, mica are a kind of rock-forming minerals, and hexagonal form of flake crystal is presented, is one of Main Rock-forming Minerals.Characteristic It is insulation, high temperature resistant, is widely used in the industries such as coating, paint, electrical isolation.Main application is industrially with the most use to be Secondly muscovite is phlogopite.It is widely used in building material industry, fire protection sector, extinguishing chemical, welding rod, plastics, electricity absolutely The chemical engineering industries such as edge, papermaking, bituminized paper, rubber, pearlescent pigment.Ultrafine mica powder makees the functions such as plastics, coating, paint, rubber Property filler, can be improved its mechanical strength, enhancing toughness, adhesive force is anti-aging and corrosion resistant type etc..Except with high electrical isolation Property, antiacid caustic corrosion, elasticity, outside toughness and the performances such as sliding property, heat-resistant sound-insulation, thermal expansion coefficient be small, and have surface it is smooth, The features such as radius-thickness ratio is big, form is regular, adhesive force is strong.
Needle silicon, i.e., needle-shaped Cab-O-sil, since it has, good temperature tolerance, acid-alkali-corrosive-resisting, thermal coefficient are high, height insulate, low The excellent performances such as expansion, stable chemical performance, hardness is big, are widely used in chemical industry, electronics, integrated circuit (IC), electric appliance, modeling The fields such as material, coating, advanced paint, rubber, national defence.
Preferably, the dispersing agent is sequestering organic polyphosphoric acids class dispersing agent.
Sequestering organic polyphosphoric acids class dispersing agent is a kind of organic chelate of efficient multi-purpose, it can be with softened water Matter has very strong chelating ability and dross dispersion force to metal ions such as Ca2+, Mg2+, Fe3+, prevents from sinking in dyeing and finishing process The dross that the generation of starch and other dirts generate, and can slowly dissolve and remove the silicon dirt in equipment, calcium soap precipitates object with And oligomer, it prevents metal salt to the recontamination of various fibers, improves bleaching, dyeing, the whiteness of Printing, vividness, color Fastness, while the white background recontamination of Printing and Yarn-dyed fabric can be prevented.
Preferably, the defoaming agent is organic silicon defoamer.
Organic silicon defoamer is a kind of lotion of thick white.Each industrial circle is just used for from the sixties, but extensive It is since the eighties with comprehensive fast development.As organic silicon defoamer, application field is also very extensive, increasingly Attention by all trades and professions.It is raw in the industrial departments organic silicon defoamer such as chemical industry, papermaking, coating, food, weaving, pharmacy Indispensable a kind of auxiliary agent during production, it can not only remove the foam on production process technology medium liquid level, to change It is apt to the separation, gasification, drain of technical process and other effects such as be filtered, washed, extract, distilling, evaporating, being dehydrated, drying, it is ensured that all kinds of The capacity of material splendid attire, process container.
Preferably, the levelling agent is newton-type nonionic polyether class levelling agent.
Newton-type nonionic polyether class levelling agent can promote coating to form a smooth, light during the drying and film forming process Sliding, uniform film.It can be effectively reduced and cover with paint, lacquer, colour wash, etc. liquid surface tension, improve a substance of its levelability and uniformity.It can improve The permeability for covering with paint, lacquer, colour wash, etc. liquid, increases spreadability at a possibility that spot and spot are generated when can be reduced brushing, make film forming uniformly, it is natural.
Preferably, the preservative is 1,2-benzisothiazolin-3-one.
1,2-benzisothiazolin-3-one has inhibition mould (fungi, bacterium) outstanding, and the microorganisms such as algae are organic Growth effect in medium, solve mouldy organic products caused by microbial growth, fermentation, rotten, demulsification, it is smelly, etc. one Series of problems.Therefore 1,2-benzisothiazolin-3-one is widely used in latex product, water-soluble resin, coating (cream by flourishing state Shellac varnish), acrylic acid, polymer.Poly- ammonia product, washing lotion of taking a picture, papermaking, ink, leather, in the products such as lubricating oil.
Preferably, the thickener is polyurethane associative thickener.
Polyurethane associative thickener is a kind of swollen association thickener of alkali soluble that hydrophobic grouping is modified.It can be used as aqueous painting The thickener of material or synergistic thickening agent.It has the advantages that
1, improve mobility, levelability and anti-splash.
2, microorganism and enzyme are stablized, reduces the cost of raw material.
Polyurethane associative thickener is suitable for water paint, inside and outside wall emulsion paint, water-based ink, adhesive, elastic gum The thickening of the systems such as slurry, polyurethane.
The beneficial effects of the present invention are:
1, LASD raw material environmental protection of the invention, smell is small, VOC emission amount is low, environmentally friendly.
2, LASD of the invention is liquid, sprayable, makes molding in advance without particular manufacturing craft, is constructed simpler, directly Spray gun is controlled in corresponding position spray mo(u)lding by mechanical arm, and construction cost is lower.
3, its physics of LASD of the invention, chemical property are stablized, and the more traditional pitch class acoustic material of soundproof effect is more It is good, and be not in the problem that traditional pitch class acoustic material winter is crisp, summer is viscous.
