Example Embodiment

[0015] Example 1

[0016] According to the formula in the above technical scheme, the weight parts of each component are as follows:

[0017] Saturated polyester resin 70;

[0018] Isobutyl etherified melamine formaldehyde resin 28;

[0019] Epoxy 10;

[0020] Polyether modified polydimethylsiloxane 0.01;

[0021] N-Butanol 4.6;

[0022] Dimethyl Nylonate 3;

[0023] Silane coupling agent 1.

[0024] The above weighed raw materials are mixed uniformly according to the conventional method to make a paint, and then the paint is coated on the surface of a nylon and glass fiber (containing 35% of glass fiber) material, using the same method as other paints, and then follow the baking process , Bake at 150℃ for 20 minutes, and then inspect the resulting paint film. It has strong adhesion, solvent resistance, chemical resistance, excellent performance, and good benefits; at the same time, coating on nylon can be omitted For products such as glass fiber and glass fiber, it is troublesome...

Abstract

The invention relates to a baking varnish composition, main components of which by weight percentage are: saturated polyester resin: 64-70, isobutyl ether melamine formaldehyde resin: 20-28, epoxy resin: 0-10, flatting agent: 0-0.01, solvent: 6-7.6 and silane coupling agent: 0-1. The formulation is that cross linking reaction happens on the condition that the saturated polyester resin is matched with the isobutyl ether melamine formaldehyde resin with a small amount of epoxy resin and a little silane coupling agent added to form film with excellent adhesion and materialization. The baking varnish composition can be directly coated on the surface of nylon and glass fiber free from pretreatment, has very strong corrosion resistance and is environmental-protection and nonhazardous. The paint layer generated after coated on the surface of nylon and glass fiber has strong adhesion.

Description

technical field [0001] The invention relates to a solvent type baking varnish composition, in particular to a high adhesion solvent type baking varnish composition. Background technique [0002] Paint refers to a type of film-forming substance that can dry and form a film when applied to the surface of an object, making the object beautiful and protected, or forming a film with other special functions on the surface of the object. Paint plays a protective role in different environments, so it needs to have mechanical strength, aging resistance, corrosion resistance and other characteristics. [0003] Nylon and fiberglass materials are usually coated with a layer of paint to protect them from corrosion. However, it is very difficult to coat nylon and fiberglass materials. At present, most of them have to be pre-treated and then coated with two-component paint, which brings great inconvenience to the construction. come to trouble. Contents of the invention [0004] In orde...
