2) stirring to continuing to add titanium dioxide, talcum powder, decolouring marine alga mud powder, bovine bone powder, oyster shell whiting, medical stone powder in reaction unit, and be milled to fineness of materials below 40um, is, under the condition of 500-1200 rev/min, to stir 20-30 minute at rotating speed;
3), to continuing in reaction unit to add the defoamer of ACRYLIC EMULSION, Activities of Some Plants glue composition, glycerine, ethanol, surplus and Flos Sophorae extract to reaction unit, be to stir 20-30 minute under the condition of 400-800 rev/min at rotating speed;
4) finally add the vegetable jelly composition of surplus and water adjusting viscosity to 90-110KU, cross 200 mesh sieves.
The preparation method of described a kind of environmental protection coating material, the consumption that it is characterized in that each component in step 1) is water 200-300 part, alkaloid composition 1-3 part, wetting agent 1-3 part, dispersion agent 4-6 part, defoamer 4-6 part; Step 2) in the consumption of each component be titanium dioxide 200-250 part, talcum powder 40-80 part, decolouring marine alga mud powder 30-70 part, bovine bone powder 30-70 part, oyster shell whiting 30-70 part, medical stone powder 30-50 part; In step 3), the mass parts consumption of each component is: ACRYLIC EMULSION 200-250 part, vegetable jelly composition 20-50 part, glycerine 15-30 part, ethanol 2-4 part, Flos Sophorae extract 2-4 part; In step 4), the mass parts consumption of each component is: vegetable jelly composition 20-50 part, water 200-300 part.
The preparation method of described a kind of environmental protection coating material, is characterized in that described alkaloid composition is the mixture of colchicine and syringic acid.delta.-guanidinobutyl ester, and both ratios are colchicine: syringic acid.delta.-guanidinobutyl ester=1:1.
The preparation method of described a kind of environmental protection coating material, is characterized in that described vegetable jelly composition is the mixture of carrageenin, Viscogum BE and konjak gum, and three's ratio is classified carrageenin as: Viscogum BE: konjak gum=1:1:1.。
In the present invention, ethanol working concentration is 95%; the coating that adopts the inventive method and formula to make; construction proportioning is coating: water=100:(100-20); the coating lacquer mould making is plentiful; possess good decoration functions and protection of environment function, all have good effect at smell, environmental protection, aspect of performance, smell is pure and fresh; can not distribute the obnoxious flavoures such as formaldehyde, benzene, ammonia, TVOC, also can absorb the obnoxious flavoures such as airborne formaldehyde simultaneously.
The dispersion agent that the present invention adopts is sodium polyphosphate dipersant, has good dispersion efficiency, can effectively stablize water hardness, prevents that pigment, coating from reuniting and iron ion produces brown spot, shortens pigment dispersion system; Wetting agent adopts the wetting agent D-504 of low bubble performance, and transparent yellow liquid uses with other components matching in formula, has certain froth breaking and presses down bubble effect, can improve the flow leveling of product simultaneously; Defoamer adopts mineral oil antifoam agent, and froth breaking ability is strong, is easy to other batchings and mixes, and can not cause side reaction in film process, is used in conjunction with and can reaches better wetting effect with wetting agent.Titanium dioxide adopts nano grade titanium white powder, and covering effect is good, easily disperses.Frostproofer selects glycerine to replace the poisonous ethylene glycol of tradition, health environment-friendly.
In shell powder particulate, there is unique cavity configuration, not only do not contain formaldehyde, toluene, dimethylbenzene, TVOC(volatile organic compounds) etc. objectionable impurities, but also the function that there is superpower absorption, decomposes these obnoxious flavoures, in addition, the main component calcium of oyster shell whiting, have good anti-static ability, therefore this coating anti-static effect is better.In addition, oyster shell whiting and bovine bone powder are used in conjunction with, and under the state of subatmospheric high humidity, metope absorbs airborne portion of water, and in the situation that room air is dried, the body of wall originally moisture of storage will be discharged in air, thereby forms aquatic respiration function.Meanwhile, being used in conjunction with of bovine bone powder and Flos Sophorae extract, also can effectively suppress the generation of mycete on wall, plays the antibacterial effect of insect protected, provides useful environment to people.
Decolouring marine alga mud powder is to have marine alga mud constantly to stir 40 minutes in water, then leaves standstill, and in the process of leaving standstill, makes with charcoal absorption decolouring.Marine alga mud powder has the attribute of mud, is difficult for being infected with dust, meets the reducible one-tenth mud of water, is convenient to repair; The light porous of marine alga shale, specific surface area is large, is the poor conductor of heat, electricity, sound, has heat preservation and soundproof effect, and high its particle surface conventionally of chemical stability, with electric charge, therefore can be used for adsorbing each metal ion; Medical stone is a kind of to biological nontoxic, harmless and have certain bioactive composite minerals or a medicinal rock, medical stone is porous, adsorptive power is very strong, if by medical stone grinding powder, ion stripping and adsorption strengthen, can some obnoxious flavour of active adsorption, in the present invention, oyster shell whiting has the function of the obnoxious flavoures such as absorption formaldehyde, also has the effect that improves hardness of paint film simultaneously; Bovine bone powder has the anti-function of going mouldy, and medical stone has stronger efficacy of adsorption equally, and three is used in conjunction with, and adsorption effect is stronger.
A kind of coating for wall surface of the present invention and preparation method thereof, cost is lower, preparation technology is simple, and good insect protected, sterilizing, anti-mildew effect are played in the combination of oyster shell whiting and bovine bone powder, medical stone powder, Flos Sophorae extract, metope is difficult for mildewing, raw bacterium, and smell is pure and fresh simultaneously; Product of the present invention is containing toxic substances such as formaldehyde, benzene, ammonia, and volatile toxic substance reaches zero release, and can absorb the objectionable impuritiess such as formaldehyde that indoor floor, furniture etc. comes out; The present invention also has good permeability, makes metope possess respiratory function, automatically regulates indoor air humidity.
