Problems solved by technology

Although additive flame retardants can also have a certain flame retardant effect, such flame retardants have poor flame retardant effects, large dosage, and poor compatibility with organic components. It is necessary to add a variety of chemical additives to improve the performance of the coating. , which greatly reduces the environmental protection of water-based coatings

Synthetic example 2

[0029] Synthesis of Synthesis Example 2 Phosphate Ester

[0030] Add 12mL of n-pentane bromide, 8ml of diethanolamine, 30ml of absolute ethanol and 4g of potassium silanolate to the three-necked flask, reflux and stir for 3 hours, cool, and filter to obtain the liquid; add 1.5ml of 85% phosphoric acid, 50ml of Acetone and 2g of phosphorus pentoxide were heated to 60°C, stirred and reacted for 2 hours, and the acetone was distilled off to obtain a light yellow liquid, which was phosphoric acid ester.

Synthetic example 3

[0031] Preparation of Synthetic Example 3 Composite Filler

[0032] Mix 300g of raw shell powder with 100g of aluminum phosphate and sinter at 500°C for 22min, then pulverize the sintered body and select powder with a particle size of 0.1-1.2μm; then carry out surface treatment on the powder, specifically put 200g of powder into Add 1800g of ethanol and 2.3g of hydroxyl-terminated polysiloxane powder into the container, stir for 45min, and finally dry to obtain the composite filler.

Synthetic example 4

[0033] The preparation of the alcohol ester of synthetic example 4 epoxy modification

[0034] In a nitrogen atmosphere, add 36g of bisphenol A epoxy resin, 100g of maleic anhydride and 240g of ethylene glycol into the reactor, react at 108°C for 50min, then add 6 drops of hydrochloric acid, and continue the reaction for 12min to obtain the epoxy resin Modified Alcohol Esters.

Abstract

The invention discloses an environment-friendly waterborne fire retardant coating. The environment-friendly waterborne fire retardant coating is prepared by mixing the raw materials in percentage by weight: 30-35 percent of silicone-acrylate emulsion, 10-13 percent of composite filler, 6-8 percent of epoxy modified alcohol ester and the balance of water. With the adoption of the raw materials, the coating can have excellent adhesion, the fire retardancy of a system can also be improved, each component ratio is reasonable, the compatibility is strong, and the obtained coating has long storage period, is environment-friendly and can be used for architectural ornament.

Description

technical field [0001] The invention belongs to the technical field of building decoration materials, and in particular relates to an environment-friendly water-based flame-retardant paint. Background technique [0002] Coatings are a mixture of polymer substances and ingredients, and can be coated on the surface of the substrate to form a new type of polymer material that adheres firmly and continuously. [0003] Any paint that uses water as a solvent or as a dispersion medium can be called a water-based paint. The biggest difference between water-based coatings and solvent-based coatings is that most of the organic solvents in the coatings are replaced by water, which is composed of water, organic matter, fillers, etc. Water-based coatings are the development trend of the architectural decoration industry. They have the following characteristics: use water as a solvent, save resources, reduce the risk of fire during construction, and reduce air pollution; Good adaptabili...
