Durable biomass polyphenol water-based flame retardant paint and preparation method and applications thereof

Abstract

The invention provides durable biomass polyphenol water-based flame retardant paint and a preparation method and applications thereof. The water-based flame retardant paint is mainly composed of biomass polyphenol or a combination of the biomass polyphenol and a salt through a coordination bond or/and adsorption. The preparation method is to mix the biomass polyphenol with a certain amount of water or add a binder on the basis, or to mix the biomass polyphenol with a certain amount of water and drop a salt solution or add a binder on the basis. The preparation method of the biomass polyphenolwater-based flame retardant paint is low in energy consumption, environmentally friendly and safe. The prepared biomass polyphenol water-based flame retardant paint has the advantages of durability, high flame retardant efficiency, strong adhesion, environmental protection and safety, can be directly used as water-based flame retardant paint, and can also be used as surface treatment and additiveflame retardant agents for different polymer materials.

Description

technical field [0001] The invention belongs to the technical field of water-based flame-retardant paint and its preparation and application, and in particular relates to a durable bio-based polyphenol water-based flame-retardant paint and its preparation method and application. Background technique [0002] After decades of development, polymer materials have been widely used in various fields. However, one of the main problems in its practical application is that it is flammable, and a large amount of heat and toxic gases will be generated during the combustion process, which poses a huge safety hazard to the safety of life, property, and environmental ecology. Therefore, the use of polymer materials Flame retardant has always been a technical issue that researchers continue to study. As a new type of polymer material, coatings have been widely used in steel components of buildings, steel frames of houses, hotels, buildings, airports, stations and other buildings. Theref...

Problems solved by technology

In addition to the complex structure and polarity of the existing halogen-based and phosphorus-based flame retardants, the research on flame-retardant coatings mostly focuses on solvent-based coating systems, but there are also some problems in the use of solvent-based coatings: such as volatility The release of organic matter (VOC) is large, and it is often used in combination with dangerous and flammable solvents, thus limiting its application in the field of flame retardant coatings

But unfortunately, the cost of protein, DNA, and PDA is relatively high at present, and they cannot be popularized and applied.

In addition, the above-mentioned biomass flame retardants are all water-soluble biomacromolecules, which have poor surface adhesion, no durability, and cannot form permanent flame-retardant protection. Decrease with the passage of time and the increase in the number of washings

In response to these problems, Patent Application No. 201610000885.4 discloses a functional flame-retardant starch obtained by modifying starch through molecular design as the starting material, which is compounded with water-based epoxy resin to form a water-soluble and environmentally friendly bio-based "three sources" Integral intumescent flame retardant coating system, although this system solves the disadvantages of high cost and non-washing resistance of biomacromolecule flame retardants to a certain extent, however, because this system only uses biomass starch as a carrier, it still uses traditional phosphorus Starch-based organophosphate flame retardants are prepared by chemical modification method, so it hardly contributes to improving the environmental protection and safety performance of flame retardant products
