Abstract
The invention belongs to the field of coating materials, and particularly relates to a composition of a thermosetting powder coating material. The composition is characterized by containing the components of epoxy resin, phenolic resin, acrylic resin, barium sulfate, calcium carbonate and a curing agent. The components comprise, in parts by mass, 15 to 20 parts of epoxy resin, 15 to 20 parts of phenolic resin, 20 to 30 parts of acrylic resin, 5 to 10 parts of barium sulfate, 2 to 5 parts of calcium carbonate and 2 to 5 parts of curing agent. The composition has relatively good scratch resistance and beautiful wall surface.
Description
Technical field
The invention belongs to paint field, particularly relate to a kind of powdered thermosetting compositions for coatings.
Background technology
Thermosetting powder coating is a kind of novel without solvent 100% solid powdery coating, and it has solvent-free, pollution-free, recyclable, environmental protection, the saving energy and resource, reduces labor intensity and film mechanical strength high. Thermosetting powder coating refers to using thermosetting resin as film forming matter, added the firming agent of cross-linking reaction heated after can form insoluble not molten quality hard coat. Temperature this coating high again softens without as thermoplastic coating, and can only decompose. The resin adopted due to thermosetting powder coating is the prepolymer that the degree of polymerization is relatively low, molecular weight is relatively low, so the levelability of coating is better, there is good dicoration, and low-molecular-weight prepolymer cured after, the macromole of cross-linked network can be formed, thus coating has better anti-corrosive properties and mechanical performance, therefore thermosetting powder coating development is particularly rapid.
At present, the scratch resistance of the thermosetting powder coating of commercial type is poor, affects surface of wall attractive in appearance.
Summary of the invention
The present invention is directed to above-mentioned technical problem, it is provided that the powdered thermosetting compositions for coatings that a kind of scratch resistance is relatively good, surface of wall is attractive in appearance.
In order to solve above-mentioned technical problem, the invention provides a kind of powdered thermosetting compositions for coatings, it is characterized in that: include epoxy resin, phenolic resin, acrylic resin, barium sulfate, calcium carbonate, firming agent, each component consists of epoxy resin 15-20 part, phenolic resin 15-20 part, acrylic resin 20-30 part, barium sulfate 5-10 part, calcium carbonate 2-5 part, firming agent 2-5 part according to mass fraction.
Each component consists of epoxy resin 18 parts, 18 parts of phenolic resin, acrylic resin 25 parts, 7 parts of barium sulfate, calcium carbonate 3 parts, 3 parts of firming agent according to more high quality number.
The invention have the benefit that
1, present component is fairly simple, and production cost is relatively low, and processing technique is simple;
2, scratch resistance is relatively good, and hard thing streaks the surface of wall glossiness to body of wall and has no significant effect, and surface of wall is attractive in appearance, long service life;
3, paint coatings surface has stronger mechanical performance, puncture and wearability, and the brushing base material such as body of wall, door and window is had good protection.
