Abstract
The invention discloses a kind of production methods of no benzene paint, it is characterized in that 8-12% maleic anhydride, 10-15% phthalic anhydride and 10-16%1,2-- propylene glycol are placed on a container for stirring first, it is heated to 50-80 DEG C, until being completely dissolved, then 1-3% ethylene glycol, 0.5-1% hydroquinone 35-47% polyester resin and 25-30% aromatic solvent naphtha are placed in another container and are stirred, it is heated to 50-100 DEG C, two kinds of solution are stirred at room temperature uniformly again, are then added in grinder and are ground.The paint paint film that the present invention makes is plentiful, and adhesive force is strong.Evaporation rate is moderate, using that will not pollute to the mankind and environment, has environment-friendly function.
Description
Technical field
The present invention relates to a kind of production methods of no benzene paint.
Background technique
Current many organic paints are wide in variety, widely used, and existing organic paints use benzene mostly in process of production
Solvent, benzene content would seriously pollute the environment in this way 70% or so, influence human health in paint.
Summary of the invention
The object of the invention is in order to overcome the above-mentioned deficiencies of the prior art, provide, a kind of composition is simple, is formulated and closes
Reason, reliable performance, the production method of no benzene paint free of contamination to environment and the mankind.
In order to achieve the above objectives, the present invention is realized by the following method:
A kind of production method of environment protection oil paint, it is characterised in that first by 8-12% maleic anhydride, 10-15% adjacent benzene two
Formic anhydride and 10-16% 1,2- propylene glycol are placed on a container for stirring, are heated to 50-80 DEG C, until being completely dissolved, then
1-3% ethylene glycol, 0.5-1% hydroquinone 35-47% polyester resin and 25-30% aromatic solvent naphtha are placed on another appearance
It is stirred in device, is heated to 50-100 DEG C, then two kinds of solution are stirred at room temperature uniformly, be then added in grinder and carry out
Grinding.
The present invention replaces benzene solvent with aromatic solvent naphtha, and boiling point is close to benzene solvent, but it is free of benzene,toluene,xylene.
Production and use will not pollute the mankind and environment, have environment-friendly function.Aromatic solvent naphtha of the present invention can be used for producing
Column organic paints.
Specific embodiment
Embodiment 1:
1, a container for stirring is placed on by 8kg maleic anhydride, 10kg phthalic anhydride and 10kg 1,2- propylene glycol,
It is heated to 50 DEG C.Until being completely dissolved.
2,1.5kg ethylene glycol, 0.3kg hydroquinone 40.2kg polyester resin and 30kg aromatic solvent naphtha are placed on another
It is stirred in a container, is heated to 80 DEG C.
3, two kinds of solution for obtaining process flow 1,2 are stirred at room temperature uniformly, are then added in grinder and are ground
Mill.
4, finally the mixing liquid that process flow 3 obtains is packed.
The technical process of this environment protection oil paint production and traditional paint are essentially identical, its main feature is that by aromatic solvent naphtha generation
For benzene solvent, aromatic solvent naphtha is refined by anphtha distillation, wherein being free of benzene,toluene,xylene.The paint paint film of production is rich
Full, adhesive force is strong.Evaporation rate is moderate, using that will not pollute to the mankind and environment, has environment-friendly function.
Embodiment 2:
1, it is placed in a container and is stirred by 12kg maleic anhydride, 13kg phthalic anhydride and 16kg 1,2- propylene glycol
It mixes, is heated to 50 DEG C.Until being completely dissolved.
2,2kg ethylene glycol, 1kg hydroquinone 37kg polyester resin and 25kg aromatic solvent naphtha are placed on another container
In be stirred, be heated to 80 DEG C.
3, two kinds of solution for obtaining process flow 1,2 are stirred at room temperature uniformly, are then added in grinder and are ground
Mill.
4, finally the mixing liquid that process flow 3 obtains is packed.
