Problems solved by technology

[0002] In the field of auto parts processing, in order to process the automobile hood, the automobile hood model is often processed first, and generally the automobile hood model is made of paste substitute wood, and the surface of the model is coated with paint, but the current paint The combination with the model is not good, it is easy to cause the paint to fall off. At the same time, the paste wood model has been used for a long time. Due to the influence of the environment, bacteria are easy to grow on the surface of the model, which leads to the decay of the model. Based on this, it is necessary to carry out the existing paint.

Embodiment 1

[0023] A kind of coating for automobile hood model, comprises following components by weight: 30 parts of styrene-acrylic emulsion, 20 parts of water, 2 parts of kaolin, 3 parts of aluminum powder, 5 parts of aluminum oxide, 1 part of Zirconium dioxide, 0.5 parts of fluorosilicate, 0.5 parts of nano silver, and 0.5 parts of phytobicides.

[0024] Among them, the preparation method of the plant fungicide is: after pulverizing privet leaves, vines and autumn maple, adding cellulase for enzymolysis, then placing the enzymatic hydrolyzate in a closed container, and then feeding water vapor to make the pressure in the closed container 2Mpa , keep it for 0.5h, then release the pressure to 10pa within 8s, continue to introduce water vapor to make the pressure in the airtight container 0.5Mpa, keep it for 10min, then release the pressure to 5pa within 5s, keep it for 1min, take it out to get the plant fungicide. The mass ratio of privet leaf, vine vine, autumn maple and cellulase is 2...

Embodiment 2

[0031] A kind of coating for automobile hood model, comprises following components by weight: 35 parts of styrene-acrylic emulsion, 25 parts of water, 3 parts of kaolin, 4 parts of aluminum powder, 8 parts of aluminum oxide, 2 parts of Zirconium dioxide, 0.8 parts of fluorosilicate, 0.8 parts of nano silver, and 0.8 parts of phytobicides.

[0032] Among them, the preparation method of the plant fungicide is as follows: after pulverizing privet leaves, vines and autumn maple, adding cellulase for enzymolysis, then placing the enzymatic hydrolyzate in an airtight container, and then feeding water vapor to make the pressure in the airtight container 3Mpa , keep it for 0.8h, then release the pressure to 10pa within 8s, continue to pass water vapor to make the pressure in the airtight container 0.8Mpa, keep it for 10min, then release the pressure to 5pa within 5s, keep it for 1min, take it out to get the plant fungicide. The mass ratio of privet leaf, vine vine, autumn maple and ce...

Embodiment 3

[0039] A kind of coating for automobile hood model, comprises following components by weight: 40 parts of styrene-acrylic emulsion, 30 parts of water, 5 parts of kaolin, 6 parts of aluminum powder, 10 parts of aluminum oxide, 3 parts of Zirconium dioxide, 1 part of fluorosilicate, 1 part of nano silver, 1 part of phytoncide.

[0040]Among them, the preparation method of the plant fungicide is as follows: after pulverizing privet leaves, vines and autumn maple, adding cellulase for enzymolysis, then placing the enzymatic hydrolyzate in an airtight container, and then feeding water vapor to make the pressure in the airtight container 3Mpa , keep it for 1h, then release the pressure to 10pa within 8s, continue to introduce water vapor to make the pressure in the airtight container 1Mpa, keep it for 20min, then release the pressure to 5pa within 5s, keep it for 1min, take it out to get the plant fungicide. The mass ratio of privet leaf, vine vine, autumn maple and cellulase is 3:2...

Abstract

The invention proposes a coating for an automobile engine hood model. The coating contains kaolin, the kaolin is added into the coating, pores in asurface of the model are reduced, and a compact coating can be formed on the surface of the model, so that the adhesive force between the coating and the model is greatly enhanced. The coating for the automobile engine hood model further comprises a plant bactericide, the plant bactericide is extracted from glossy privet leaves, gelsemium elegans and bischofia javanica as raw materials, tests show that the coating has a good sterilization effect, meanwhile, the coating further comprises nano-silver, and the sterilization rate of the coating can be further increased through the synergistic effect between the nano-silver and the plant bactericide.The invention discloses the coating for the automobile engine hood model. When the plant bactericide is prepared, firstly the glossy privet leaves, the gelsemium and the bischofia javanica are subjected to enzymolysis with enzyme, and then water vapor is introduced to enable the raw materials to be at high pressure, so that the water vapor permeates into the raw materials more easily, pressure isrelieved in a short time, the pressure is reduced instantaneously, the raw materials burst to be sprayed out from the inside, and active ingredients in the raw materials can be dissolved out quickly.
