Methods to solve paint falling of PP material in spraying industry

  PP treatment agent is similar to glue in function, but it cannot be directly called glue, because it is essentially different from glue
The function of PP treatment agent is to effectively wet the surface of the material, which is equivalent to the interlayer auxiliary between the substrate and the paint, enhance the intermolecular force and enhance the adhesion of PP substrate
It is widely used in the spraying industry to solve the problem that the paint falling test of PP substrate fails Because PP plastic material has light resistance, oil resistance, corrosion resistance and light material performance, the spraying industry is widely used in the production of auto parts and mobile phone cases
Due to its low polarity, high crystallinity and poor surface adhesion during painting, PP is a hard to adhere material
As a surface treatment process, PP plastic spray painting is an important link
Plastic spray painting will select different paints according to different product appearance, so as to achieve its effect
The quality of products depends on the effect of spray painting
However, in the production and painting process of the spraying industry, the phenomenon of poor adhesion and paint falling often occurs due to the PP material itself, which affects the product quality, reduces the production efficiency and consumes the production cost The traditional methods to solve the adhesion of PP surface will use combustion flame method and surface polishing
These methods may have some effect on changing the molecular structure of PP surface, but the effect is not obvious, which is neither safe nor time-consuming
At present, the common method to solve the adhesion of PP materials in the spraying industry is to use Jisheng PP treatment agent However, in order to fundamentally solve the problem of paint falling, the surface of PP material must be cleaned first
In addition, before painting, the material should be sprayed with a layer of Jisheng PP treatment agent to form an effective intermolecular force, so as to enhance the adhesion
The reason why Jisheng PP treatment agent can be recognized by the spraying industry is that PP treatment agent can make the substrate and paint miscible, the adhesion test can reach 5b, and the operation is simple and convenient
