Embodiment 1

[0039] Embodiment 1. The preparation of bromocarbon alkyd resin

[0040] In a 500ml four-neck flask equipped with a stirring device, an oil-water separator and a thermometer, add 60 parts of soy oil, 10 parts of pentaerythritol, and 10 parts of phthalic anhydride in sequence by mass parts, pass nitrogen protection, start stirring and condensing water, and heat up Add 0.02 parts of catalyst lithium hydroxide and 4.98 parts of xylene at 120 ° C, and continue to heat up to 180 ° C, start the heat preservation process, the heat preservation process is 50~60min; after the heat preservation stage, add 15 parts of brominated epoxy resin to control the temperature Between 180°C and 200°C, the reaction time is 90 minutes to 120 minutes. When the acid value is within 10mgKOH / g, the reaction can be stopped, the temperature is lowered to 180°C, and the water and xylene in the oil-water separator are released. Distill the xylene in the bromocarbon alkyd resin with nitrogen gas; lower the t...

Abstract

The invention relates to a bromine carbon alkyd resin transparent fireproof paint and its preparation method. The formula of the bromine carbon alkyd resin transparent fireproof paint comprises, by mass: 60%-90% of bromine carbon alkyd resin, 2%-3% of a drier, and 30%-45% of a solvent. The preparation method consists of the steps of: adding bromine carbon alkyd resin into a formula required amount of the solvent, conducting dispersion for 20-40min, adding the drier and carrying out dispersion in a multipurpose dispersion mill for 10-20min, thus obtaining the product.

Description

technical field [0001] The invention relates to polymer chemistry and polymer coating composition technology. Background technique [0002] When coating and protecting some wooden products, not only the coating is required to have a certain protective effect, but also the original style is required to be preserved. For example, for the decoration of ancient buildings, cultural relics and high-end furniture, the coating is required to maintain the original appearance of the decorations. , and can also play a role in fire prevention and decoration, which has important social benefits. So far, most paints contain auxiliary substances such as pigments and fillers, which will destroy the original decorative effect after being applied to the surface of the decorative material, and cannot meet the above requirements. Transparent fireproof coatings do not contain auxiliary substances such as fillers, and are similar to varnishes. They not only have a decorative effect, but also pla...
