Description

Ash aluminium zinc alkyd finish

Technical field

The invention belongs to metal alkyd finish field, be specifically related to a kind of grey aluminium zinc alkyd finish.

Background technology

The chemosynthesis lacquer contains benzene, formaldehyde, heavy metal etc. mostly, and a large amount of uses can cause atmosphere, Land pollution and Air quality to descend, and seriously influences for people's living environment and healthy bringing.Along with the reinforcement of society to Environmental awareness, this environment that people more and more pay attention to surviving, in order to limit objectionable impurities to the pollution of human ecological environment, the Chinese government has issued the national standards such as GB18581-2001 " limits of harmful substances in the coating ", GB18582-2001 " limits of harmful substances in the coating ".The formulation of standard limits and has reduced the pollution of objectionable impurities to a certain extent, but is still to contain the objectionable impuritiess such as a certain amount of heavy metal, formaldehyde, alkane alkene organism, isocyanic ester in the product that can be up to standard.Tradition colour polyurethane furniture lacquer can distribute poisonous irritant gas, is detrimental to health, and complex process, must the professional construct the construction inconvenience of doing it yourself.And much environment-friendly type coatings are in order to reach environmental protection, and some performances after the paint film forming can not be guaranteed.

Summary of the invention

What the present invention will solve is exactly that existing chemosynthesis lacquer causes environmental pollution easily because mostly containing benzene, formaldehyde, heavy metal etc., affect the problem of HUMAN HEALTH, a kind of heavy metal ion such as chemical classes solvent and mercury, aluminium, chromium that do not contain are provided, nontoxic having no irritating odor, and easy construction, widely applicable MED high-performance electrophoresis lacquer.

The present invention is prepared and is got by natural resin, thinner, pigment, filler, the weight proportion of each component is: natural resin 58-62%, pigment 8-12%, filler 10-15%, thinner 15-20%, wherein natural resin is got by vegetables oil and vegetable solid resin, the natural phant solvent of thinner for from water, refining, and pigment is natural pigment or natural goods processed pigment.

The natural resin that the present invention adopts is got at 280 ℃ of-290 ℃ of lower heat refinings by weight by following ingredients: oleum lini 60-63%, tung oil 14-16%, rosin 11-13%, turps 9-11%, wherein oleum lini is that essence is floated type, and tung oil, rosin, turps are state's one-level.

The thinner that the present invention adopts is turps or spearmint oil; Pigment is selected natural pigment or natural goods processed pigment, such as titanium dioxide, and organic middle Huang; Filler is available calcium carbonate, talcum powder, coarse whiting etc., and for reaching good extinction effect, preferred calcium carbonate is the preparation of convenient lacquer, preferred calcium carbonate superfine powder.

1

The present invention has following advantage:

1, each moiety is natural product, does not contain the heavy metal ion such as the poisonous chemical classes solvent such as benzene, toluene and mercury, aluminium, cadmium, lead, does not namely contain any toxic and harmful substance.

2, can distribute natural plant fragrance.

3, poisonous harmless, have no irritating odor floride-free acid esters poison gas volatilization, health environment-friendly.

4, excellent performance, fast drying, color various, bright-colored, ornamental strong, sticking power is good, hardness is high, opacifying power is high, snappiness is good, paint film is plentiful, hard, the moisture-proof scrubbing resistance.

5, the present invention constructs simply, uses widely, can brush on iron and steel, woodenware, cement wall surface, paint film is plentiful,

Test item	Technical indicator	Assay
			Benzene %	≤0.5	Do not detect
Toluene and dimethylbenzene summation %	10	Do not detect

Hard, the moisture-proof scrubbing resistance, levelling property is splendid, and feel is fine and smooth, and is inhibited from yellowing, especially can play a very good protection to wood furniture.

Table 1 is the detected result of the thinner of the present invention's use, and wherein benzene, toluene and detecting of dimethylbenzene summation are limited to 0.001%:
