Description
Technical field
The present invention relates to technical field of coatings, are specifically related to one kind and changing modified propylene acid primer and preparation method thereof.
Background technology
Priming paint is the first layer of paint system, for improving the adhesive force of finishing coat, the richness for increasing finishing coat, providing alkali resistant
Property, anti-corrosion function etc. is provided, while can ensure the uniform pickup of finishing coat, paint system is made to play optimum efficiency.Surface paint quality
Priming paint can not be had to well, this saying is not right, because finishing coat is different from the function of priming paint, finishing coat more lays particular emphasis on final dress
Decorations and apparent effect, and priming paint then lays particular emphasis on and improves adhesive force, anti-corrosion function, alkali resistance etc..
Priming paint refers to the coating for being directly applied to body surface as finishing coat solid foundation.It is required that the adhesion-tight on object plane,
To increase the adhesive force of upper coating, the dicoration of finishing coat is improved.It can be divided into priming coat, base coat according to coating specification
Deng.
The effect of priming paint is that：
1. closing：Some metope alkalinity are stronger, and alkali flower, scientific name " accumulation of salt in the surface soil ", such case are generated after the immersions such as damp gas and water
It causes coating surface to form crateriform protrusion, forms one layer of alkali frost in coating surface when serious, finally paint film is made to destroy.Latex
Paint priming paint can play sealing process, alleviate such case.This requires priming paint to have preferable water resistance.
2. adhesive force：Emulsion content is higher in priming paint, and adhesive force is stronger.The binding force of emulsion paint film and metope can be improved.
This requirement just needs requirement priming paint to have the performance of cracking resistance, because being had out once priming paint cracks finishing coat inevitably
The phenomenon that splitting influences the beauty of figure layer.
One layer of wash coats are brushed before brushing finish paint can not only save decoration cost, come from long-range and decorative effect
It sees, applying priming more has the advantages of getting twice the result with half the effort.Meanwhile the good adhesive force of priming paint makes metope more flatten out cunning, and finishing coat is enabled to be more easy to
It brushes, reduces the usage amount of finishing coat.Thus, which metope not only avoids paint disease, but also brushing effects are applied conducive to longer time holding.
But the scarce capacity of existing priming paint often water resistance and cracking resistance, this requires it is proposed that a kind of new bottom
It paints to improve this phenomenon.
