Embodiment 1-4

[0047] The preparation raw material of the PVDF solid fluorocarbon coating of embodiment 1-5, specifically as shown in table 1:

[0048] The preparation method of the PVDF solid fluorocarbon coating of embodiment 1-5, comprises the following steps:

[0049] Calcium stearate, calcium lauricate and zinc stearate with a weight ratio of 2:7:2 were placed in a ball mill and ball milled for 35 minutes at a temperature of 95°C to obtain a composite stabilizer with a particle size of 20 μm ;

[0050] PVDF polyvinylidene fluoride, fluororesin, acrylic resin, polyurethane and N,N-dimethylformamide are pre-mixed, and the conditions of the pre-mixing are: the stirring rate is 1500r / min, the time is 35min, and the temperature is At 65°C, mixture A was obtained;

[0051] Continue to add magnesium oxide, zinc oxide and the composite stabilizer to the mixture A, adjust the stirring frequency, stir evenly, stir at 80°C and keep it warm for 10 minutes to obtain the mixture B;

Abstract

The invention provides a PVDF (Polyvinylidene Fluoride) solid fluorocarbon coating and a preparation method thereof. The PVDF solid fluorocarbon coating is prepared from the following raw materials: PVDF, fluororesin, acrylic resin, polyurethane, amide, magnesium oxide, zinc oxide, a compound stabilizer, benzoin, a flatting agent, a curing agent and pigment. By optimizing the preparation raw materials and the preparation process, the PVDF solid fluorocarbon coating with excellent mechanical properties, stain resistance and thermal stability can be comprehensively obtained, and by adding the compound stabilizer, the treated compound stabilizer has more excellent dispersity, and the service life of the PVDF solid fluorocarbon coating is prolonged. According to the present invention, with the combination of the PVDF polyvinylidene fluoride, the fluororesin, the acrylic resin, the polyurethane and the amide, the obtained coating film with the excellent stability can be easily obtained, and the yellowing of the coating caused by baking can be significantly inhibited.

Description

technical field [0001] The invention relates to the field of paint preparation, in particular to a PVDF solid fluorocarbon paint and a preparation method thereof. Background technique [0002] PVDF fluorocarbon coatings are high-performance coatings and are often used as topcoats for metal components. Water-based PVDF polyvinylidene fluoride fluorocarbon coatings also exist in the prior art, which are mainly prepared by hydrocarbon solvents and oxygen-containing solvents, and are relatively complicated in use. , There are many requirements, such as construction conditions and matching materials; secondly, the coating itself is rigid, insufficient in elasticity, and when the surface material of the coated object is not suitable, it is also affected by cracking, peeling, etc., and the service life is not long ; Again, it pollutes the environment. Compared with PVDF solid fluorocarbon coatings, the organic volatiles of solvent-based coatings are extremely unfriendly to the envi...
