Patent Publication No. CN103435952B discloses a phosphate nanocomposite flame retardant masterbatch and its preparation method. The flame retardant masterbatch is modified by hydroquinone bis(diphenyl phosphate) and KH550 coupling agent Organoclay is prepared by physical blending at 100°C for 5 hours at high speed. Phosphate ester and organoclay in this flame retardant masterbatch are prepared by simple physical blending, and the product has poor transparency
[0004] Organic montmorillonite and nano-silica are usually white powders, and the nanocomposite materials of organic montmorillonite and nano-silica prepared by physical blending have poor transparency and cannot be used to prepare transparent materials
In existing reports, the application of nano-silica and organic montmorillonite in fire-resistant coatings is mainly concentrated in the field of non-transparent fire-resistant coatings, while there are few studies on the application of nano-fillers synergistically enhanced transparent fire-resistant coatings
In addition, nano-silica and organic montmorillonite in existing reports are mainly added to nano-fireproof coatings through physical blending, and adding nano-fillers in the form of simple physical blending will increase the hiding power of fire-resistant coatings, resulting in transparent The decorative effect of fire retardant coatings has deteriorated, which cannot meet the application requirements of transparent fire retardant coatings

Embodiment 1

[0054] In the present embodiment, the preparation method of nano-expansive transparent fireproof coating comprises the following steps:

[0055] (1) Preparation of nano-organic montmorillonite grafted acid phosphate

[0056] In a 1L three-necked flask, 100g of nano-montmorillonite Na + -MMT is placed in 200g of deionized water to make a suspension of montmorillonite, and then 2 times the mass of nanometer montmorillonite, that is, 200g of cetyltrimethylammonium bromide CTAB, is completely dissolved in deionized water to prepare a solution 1. Heat the suspension in a constant temperature water bath at 90°C and stir for 0.5 hours, then add solution 1 to react, after 3 hours of reaction, stop heating, and after standing for 24 hours, the product after removing the upper solution is suction-filtered and washed several times until the product No Br in - After that (no light yellow precipitate was detected by AgNO3), it was dried at 80°C for 72 hours, and ground into 150-mesh powd...

Embodiment 2

[0063] In the present embodiment, the preparation method of nano-expansive transparent fireproof coating comprises the following steps:

[0064] (1) Preparation of nano-organic montmorillonite grafted acid phosphate

[0065] In a 1L three-necked flask, 100g of nano-montmorillonite Na + -MMT is placed in the deionized water of 300g to make the suspension of montmorillonite, then the hexadecyltrimethylammonium bromide CTAB of 3 mass times of montmorillonite is dissolved in deionized water completely and is prepared into solution one of 300g , heat the suspension in a constant temperature water bath at 70°C and stir for 1 hour, then add solution 1 to react, after reacting for 5 hours, stop heating, and after standing for 24 hours, the product after removing the upper solution is suction filtered and washed several times until there is no Br - After that (no light yellow precipitate was detected by AgNO3), it was dried at 80°C for 72 hours, and ground into a 300-mesh powder with...

Embodiment 3

[0072] In the present embodiment, the preparation method of nano-expansive transparent fireproof coating comprises the following steps:

[0073] (1) Preparation of nano-organic montmorillonite grafted acid phosphate

[0074] In a 1L three-necked flask, 100g of nano-montmorillonite Na+-MMT was placed in 250g of deionized water to make a suspension of montmorillonite, and then 200g of hexadecyltrimethyl Ammonium bromide CTAB was completely dissolved in deionized water to prepare solution 1. Heat the suspension in a constant temperature water bath at 80°C and stir for 1 hour, then add solution 1 to react. After 4 hours of reaction, stop heating, and after standing for 24 hours, remove the upper layer The product after the solution is suction filtered and washed several times until there is no Br in the product - After that (no light yellow precipitate was detected by AgNO3), it was dried at 80°C for 72 hours, and ground into 200-mesh powder with a ball mill to make nano-organic ...

Abstract

The invention discloses nano expanding type transparent fireproof paint and a preparation method thereof.The paint comprises a component A and a component B.The component A contains nano filler grafted phosphate ester acid, and the component B contains melamine resin.The paint has the advantages that nano silicon dioxide and organic montmorillonite are chemically grafted to phosphate ester acid, so that nano filler is evenly dispersed in a coating, and the coating transparency, mobility and compatibility problems caused by physical mixing are effectively avoided.The nano filler, phosphate ester acid and amino resin are introduced into the transparent fireproof paint so as to form a compact expanding carbon layer structure which has a good fireproof protective effect on a base material.Nano silicon dioxide, organic montmorillonite and an expanding flame-retardant agent have a synergistic effect and can obviously improve the fireproof protective effect of an expanding carbon layer.The nano expanding type transparent fireproof paint is wide in raw material resource, low in cost and convenient to operate.

Description

technical field [0001] The invention relates to the fireproof material field of chemical technology, in particular to a nano-expansion transparent fireproof coating and a preparation method thereof. Background technique [0002] Today, with the rapid development of science and technology, modern buildings, ancient buildings, engineering structural materials and other fields have higher and higher fire protection requirements for decorative coatings. Traditional fireproof coatings and decorative coatings cannot meet the requirements of modern buildings and ancient buildings in terms of fire protection and decoration. demand. Transparent fire-resistant coatings can maintain the texture, appearance, and aesthetics of the substrate of the engineering structure, and have excellent fire-proof performance. They can be widely used in ancient buildings, modern buildings, cultural relics protection, and high-end decoration. The fire performance of intumescent transparent fireproof co...
