Embodiment 1

[0019] Example 1: A safe industrial alkyd paint prepared by weight percentage of the following ingredients: 59% 1K resin, 11% pigment, 14% filler, and 16% thinner.

[0020] Said 1K resin is synthesized at 245℃ by weight ratio of the following ingredients: 152kg of linseed oil, 98kg of benzoic acid, 150kg of pentaerythritol, 0.4kg of lithium hydroxide, put into the reactor, and then keep it warm for 40-45 minutes, and check the balance Rate (sample: methanol = 1:3 clear), when the clearing rate reaches the standard, the temperature will be lowered to below 200 ℃, add 152kg of phthalic anhydride, and then continue to heat, when it reaches 260 ℃, continue to keep the temperature until the viscosity is coated-4 cups of 300-320S / (25 ±2°C), then cool to 200°C, dilute the material with 435kg ethyl acetoacetate from the kettle to a 4-cup 180-200S / (25±2°C), and finally filter to obtain 1K resin.

Embodiment 2

[0022] Put 162kg of linseed oil, 100kg of benzoic acid, 155kg of pentaerythritol, and 0.3kg of lithium hydroxide into the reactor, stir and raise the temperature to 250°C, then keep it warm for 40-45 minutes, and detect the clearing rate (sample: methanol=1:3 clear), When the clearing rate reaches the standard, the temperature is lowered to below 200℃, 150kg of phthalic anhydride is added, and then heating is continued. When the temperature reaches 260℃, the temperature is kept until the viscosity is coated with 4 cups of 300-320S / (25±2℃), and then the temperature is reduced to 200℃. Dilute the kettle with 432.7kg of ethyl acetoacetate to reach the required viscosity: paint-4 cups of 180-200S / (25±2°C), filter into the tank for use to obtain 1K resin.

[0023] Take 580kg of 1K resin, 80kg of titanium dioxide (rutile type), 100kg of superfine calcium carbonate (800 mesh), 150kg of ethyl acetoacetate solvent, put 300kg of 1K resin into the pot, add 80kg of titanium dioxide, 100kg of ...

Abstract

The invention relates to safe industrial alcohol acid coating. The coating is prepared from the following components in percentage by weight: 58-62 percent of 1K resin, 8-12 percent of pigment, 10-15percent of filler and 15-20 percent of a diluting agent, wherein 1K resin is synthesized from the following components in percentage by weight at 230-260 DEG C: 15.2-16.2 percent of flaxseed oil, 9-10.2 percent of benzoic acid, 14.2-15.5 percent of pentaerythritol, 15-15.7 percent of phthalic anhydride, 0.03-0.05 percent of lithium hydroxide and 43-46 percent of ethyl acetoacetate solvent, whereinthe 1K resin has mass indexes of acid value (mkoh / g) being less than or equal to 10, solid being 53-57 percent, viscosity (Tu-4 cup, S / 23+ / -2 DEG C) being 200-400 and fineness (mu m) being less thanor equal to 20.

Description

Technical field [0001] The invention belongs to the technical field of industrial alkyd paints, relates to products in the storage and transportation fields of paints, and specifically relates to a safe industrial alkyd paint and a preparation method thereof. Background technique [0002] Traditional alkyd paints use solvents such as toluene, xylene, heavy aromatics and other chemicals, which emit toxic and irritating gases during construction, which endanger human health and pollute the atmosphere. With the strengthening of society's environmental awareness, the market urgently needs a product that can replace traditional alkyd paint. Summary of the invention [0003] The purpose of the present invention is to provide a safe industrial alkyd paint and a preparation method thereof, which will not emit toxic gas during construction, and belong to non-hazardous chemical products below Class 3 during storage and transportation. [0004] In order to achieve the above objectives, the te...
