Embodiment Construction

[0011] The light-curing dip top paint prepared according to this formula has a fast curing speed and good effect after being exposed to light. The top is plump and has good adhesion without peeling off. Use the pencil of light-curing top paint of the present invention, can be stained with the pencil paint of desired color immediately after curing, and the color paint that this moment is applied can dry about between 30 minutes to 1 hour, has not only improved pencil quality like this , but also greatly improved the pencil production efficiency.

[0012] The viscosity of light-curing topcoats will vary with the seasons. For this reason, the diluent should be increased in winter to reduce the viscosity of the light-curing topcoat, and the resin content should be increased in summer to increase the viscosity of the light-curable topcoat. At the same time, in order to improve the adhesion of the light-cured topcoat and reduce the cost of the product, 20% of 3136 alkyd resi...

Abstract

The invention is a kind of solid lacker stained withpeak,which buildup is single and made up of epoxy acrylic resin as ac oligomerization, third-hydroxymethyl-propane, and third-acryate as ac releasing agent, NO.3136 alkide resin, photosensitizer and so on. The lacker has many strongpoints, for example, high curing speed, good effect, chubby coping, high ashesion and no desquamating, because the compounding formula is advisability, especially mixed with photochromic. stainded with the top of vimineous material like pencils, the lacker will change into solid under the black light within 20 seconds and be free from the dampness, so, the drying time is shorter and surface quality and the production efficiency of the pencils will be improved. The NO.3136 alkide resin can improves the binding energy between the lacker and the coating substance, in this way, the cost will be lower.

Description

Technical field [0001] The present invention relates to a coating composition characterized by its physical properties, and more particularly to a light-curing topcoat. Background technique [0002] Existing technology all is to adopt traditional nitro-lacquer when being applied to the top of slender rod, for example the top of pencil, i.e. the topping process in the pencil manufacturing process. When using this paint, the whole topping process needs It is done in three times. After each dipping, the paint must be dried before proceeding to the next dipping process. However, the drying time of nitro paint is longer, and it takes about 2 hours each time on average. If you encounter humid weather, the indoor humidity is high, not only will it take longer to dry, but it will also affect the quality of the top. Contents of the invention [0003] In order to overcome the shortcomings of the prior art, the present invention provides a one-component light-curing top paint. It i...
