Description
Technical field
The present invention relates to paint preparation technical field, specifically a kind of vehicle water colour paints and preparation method thereof.
Background technique
Paint early stage is called " paint " mostly using vegetable oil as primary raw material, such as the ripe paulownia of health environment-friendly ecosystem
Oil.Whether traditional using natural materials to synthesize chemical products in the coating products of raw material or modern development is former
The coating products of material, belong to organic chemical industry's macromolecular material, are formed by film and belong to high-molecular compound type.According to existing
The classification for the chemical products that generation passes through, coating belong to fine chemical product, and modern coating is gradually becoming a kind of multi-functional
The engineering material of property, is an important industry in chemical industry.
More authoritative " coating process " book of Chinese paint industry is defined such that " coating is a kind of material, this material
Material can be coated in object surface with different construction technologies, and formation adherency is secured, has some strength, continuous solid-state thin
Film.The film common name film formed in this way, also known as paint film or coating."
Paint adhesion refers to the ability be combineding with each other between paint films and coated article surface or between coating, and adhesive force is
One important technical indicator is a series of premise that paint film has performances, we judge that the standard of paint adhesion is mainly
See the percentage for the quantity and hundred lattice that finishing coat or electroplated layer are sticked up by adhesive tape, paint adhesion one is divided into five grades:
1, ISO grade: 5=ASTM grade: 0B, this peeling area for representing paint are greater than 65%；
2, ISO grade: 4=ASTM grade: 1B, some some or all of peelings of grid peel off area and are greater than 35%-
65%；
3, ISO grade: 3=ASTM grade: 2B, representing has part peeling or large area paint flake along notching edge, very
It is peeled off to the Box Section having by full wafer, area is more than 15%-35%；
4, ISO grade: 2=ASTM grade: 3B represents notch and intersection edge by peeling area and is greater than 5%-15%；
5, ISO grade: 1=ASTM grade: 4B, this, which is represented, has the paint flake of small pieces, the area Hua Ge in the intersection of notch
Interior actual spoilage is less than or equal to 5%；
6, ISO grade: 0=ASTM grade: 5B, this represent grid edges not to have any peeling, the complete light of notching edge
Sliding, this is the adhesive force of highest level；
Existing automotive paints comprehensive performance is poor, and not only color representation power is weaker, but also paint adhesion is not high, can not
Meet the use actually sprayed, needs to be improved.
