Description

Technical Field

[0001] This invention belongs to the field of coating technology, specifically relating to a high-temperature resistant and sun-proof coating for tea trays and its manufacturing method. Background Technology

[0002] my country has a long history of tea culture. Many people brew a pot of tea in their leisure time or when entertaining guests, which has led to the tradition of making friends over tea.

[0003] In recent years, small tea sets have become popular in the market. More and more people bring tea sets when they choose to go on road trips, so they can brew a pot of tea for themselves during rest periods and relieve their fatigue.

[0004] Chinese patent application number 202310338327.9 discloses a water-based coating composition for tea trays, in which carboxylated polysiloxane emulsion improves the density, water resistance, toughness, and adhesion of the coating. However, if such a tea tray is used outdoors, especially in summer, its shortcomings in high-temperature resistance and sun protection become apparent.

[0005] In order to adapt to market demand and improve product competitiveness, the applicant needs to develop a tea tray coating suitable for outdoor use, with high temperature resistance and sun protection properties, to extend the service life of the tea tray. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a tea tray coating that is suitable for outdoor use, has high temperature resistance and sun protection properties, and improves the service life of the tea tray.

[0007] The present invention adopts the following technical solution:

[0008] A high-temperature resistant and sun-proof tea tray coating includes a coating body and a filler, wherein the coating body includes the following components by mass parts: 300-350 parts of waterborne epoxy resin, 8-11 parts of methyl hexahydrophthalic anhydride, 6-7 parts of anhydrous sodium sulfate, 10-11 parts of polyisobutylene succinimide, and 3-5 parts of allyl polyoxyethylene ether.

[0009] The filler comprises the following components by mass parts: 8-11 parts of nano aluminum hydroxide, 10-13 parts of nano titanium dioxide, 6-8 parts of spiral carbon nanotubes, 2-4 parts of nano zirconium powder, 3-4 parts of fused alumina, and 4-5 parts of potassium hexatitanate whiskers.

[0010] Furthermore, the coating body also includes the following components in parts by mass: 10-12 parts of mercaptopropylmethyldimethoxysilane and 11-12 parts of N-[3-(trimethoxysilyl)propyl]aniline.

[0011] Furthermore, the coating body also includes the following components in parts by weight: 8-9 parts of defoamer L-30 emulsion and 5-6 parts of butynediol diethoxy ether.

[0012] Furthermore, the coating body also includes the following components in parts by weight: 3-5 parts of polyarylether ketone nitrile and 6-8 parts of silicone-acrylic emulsion.

[0013] The method for manufacturing the high-temperature resistant and sun-proof coating for tea trays includes the following steps:

[0014] Step 1: Preparation of the coating body

[0015] According to the stated mass fractions, the components are mixed and stirred evenly to obtain the coating body;

[0016] Step 2: Preparation of filler

[0017] According to the stated mass fractions, the charred gemstone is ground into particles with a diameter of 0.2~0.3μm, and then mixed evenly with the nano aluminum hydroxide, nano titanium dioxide, spiral carbon nanotubes, nano zirconium powder, and potassium hexatitanate whiskers to obtain a filler.

[0018] Step 3: Prepare a high-temperature resistant and sun-proof coating for tea trays.

[0019] Mix the paint body obtained in step one and the filler obtained in step two evenly to obtain a high-temperature resistant and sun-proof tea tray paint.

[0020] The obtained high-temperature resistant and sun-proof tea tray coating is applied to the surface of the tea tray, forming a coating layer on the surface of the tea tray, and the resulting tea tray has the properties of high-temperature resistance and sun protection.

[0021] Compared with the prior art, the present invention has the following advantages:

[0022] First, the tea tray coating of the present invention uses epoxy resin as the main raw material, methyl hexahydrophthalic anhydride and anhydrous sodium sulfate as curing agents, and polyarylether ketone nitrile and silicone acrylic emulsion as film-forming agents in order to improve its strength, so that the entire coating can better cover the tea tray when forming the coating and improve the strength of the coating.

[0023] Secondly, to further improve the performance of the coating, nano-titanium dioxide, spiral carbon nanotubes, nano-zirconium powder, fused alumina, and potassium hexatitanate whiskers are used as the main fillers. Polyisobutylene succinimide and allyl polyoxyethylene ether are used as dispersants to ensure the fillers are thoroughly mixed throughout the coating. Simultaneously, to prevent bubbles generated by the addition of solid fillers, defoamer L-30 emulsion and butynediol diethoxy ether are used as a mixed defoamer to reduce bubble formation in the coating. Furthermore, mercaptopropylmethyl dimethoxysilane and N-[3-(trimethoxysilyl)propyl]aniline are used as coupling agents to further enhance the stability between the various components of the coating. Thus, the addition of fillers improves the strength of the coating on the tea tray surface, giving it high-temperature and sun-resistant properties, allowing for outdoor use and extending its service life.
