Embodiment Construction

[0019] The present invention will be further described below in conjunction with embodiment.

[0020] First put 10g of cyclohexanone into a container with a stirrer, and add 18g of E-20 epoxy resin under stirring to make it completely dissolved. Then add 6g of talcum powder, 1g of white carbon black, 8g of zinc phosphate, 7g of barium sulfate and 30g of magnetic iron oxide in sequence, stir evenly, grind, and finally filter.

[0021] When using, first polish and clean the surface of the automobile workpiece. Before painting, add the required amount of this automotive primer into the mixing container, then add 20%-30% of non-toxic modified amine T31 curing agent, stir well before use.

[0022] T31 curing agent is also an active toughening agent for epoxy resin. It has good flexibility of paint film, strong adhesion to metal and non-metal, low toxicity to human body, fast drying, and can be cured at a low temperature of 0°C. membrane.

Abstract

The invention provides an auto-primer comprising the following components: E-20 epoxy resin, magnetic ferric oxide, barium sulfate, talc powder, zinc phosphate, cyclohexanone and white carbon black. The auto-primer provided in the invention is prepared from the epoxy resin having excellent corrosion resistance and the magnetic ferric oxide pigment as major components and other auxiliaries added thereto, and has the characteristics of low temperature setting, quick drying, oil resistance, chemical corrosion resistance, salt mist resistance, non-toxicity and the like; besides, the auto-primer can be matched with other automobile coatings in use; therefore, the auto-primer is appropriate and cheap.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to an automobile primer. Background technique [0002] When the car is running at high speed, due to atmospheric erosion, wind, rain, sun, chemical pollution, dust impact, etc., the coating of the car body will often lose light, fade, crack, differentiate, and rust. Therefore, high-quality primer is a very important part of the anti-corrosion of automobile body. The automotive primers currently on the market have general comprehensive performance and cannot meet the needs of the market. Contents of the invention [0003] The invention solves the disadvantages of the prior art, and provides an automobile primer, which can stably and long-termly play the antifouling effect of the bottom of the ship. [0004] In order to achieve the above purpose, the following technical solutions are adopted: [0005] A kind of automotive primer, the components and parts by weight of the primer a...
