preparation example Construction

[0040] The preparation method of the above-mentioned high temperature resistant and flame retardant composite material comprises the following steps:

[0041] Preparation of component A: put the material components of component A into the reactor, stir at 20-50° C. and a rotating speed of 900-1000 r / min for 3-10 hours, and mix evenly to form component A;

[0042] Preparation of component B: put the material components of component B into a container, stir and mix evenly to form component B;

[0043] Component A and Component B are separately packaged in their respective containers, and then combined into pairs and uniformly packaged into barrels or boxes, that is, high temperature resistant and flame retardant composite materials. The ratio of 1:1 is mixed evenly and then sprayed directly.

[0044] The technical performance of the high temperature resistant flame retardant composite material of the present invention is as follows:

[0045] 1. Applicable temperature: ≤1000℃; ...

Embodiment 1

[0053] Add 1 part by mass of toluene-2,4-diisocyanate, 3 parts perfluoropropylene oxide, 1 part hydroxy silicone oil, 0.05 part of dibutyltin dilaurate, and 1 part of hexafluoroacetone into a sealed container equipped with a nitrogen conduit When the temperature was raised to 80°C under the protection of nitrogen, 1 part of toluene-2,4-diisocyanate was added dropwise, after 5 hours of reaction, 0.2 part of ethylenediamine was added, and the reaction was continued for 1 hour to obtain organofluorosilicon modified. Polyurethane.

[0054] Put 80 kilograms of organofluorosilicon modified polyurethane, 5 kilograms of polytetrafluoroethylene micropowder, 1 kilogram of antimony trioxide, and 5 kilograms of hexafluoropropylene trimer into a reactor. Stir for 3 hours at high speed, and mix well.

Embodiment 2

[0056] 3 parts of toluene-2,4-diisocyanate, 5 parts of bisphenol AF, 1 part of hydroxysilicone oil, 0.1 part of dibutyltin dilaurate and 5 parts of hexafluoroacetone were added to a sealed container equipped with a nitrogen conduit in mass parts, When the temperature was raised to 100°C under the protection of nitrogen, 5 parts of toluene-2,4-diisocyanate was added dropwise, after 10 hours of reaction, 2 parts of ethylenediamine were added, and the reaction was continued for 10 hours to prepare the organofluorosilicon modified Polyurethane.

[0057] Put 90 kilograms of organofluorosilicon modified polyurethane, 1 kilogram of polytetrafluoroethylene micropowder, 5 kilograms of antimony trioxide, and 10 kilograms of hexafluoropropylene trimer into a reactor. Stir for 10 hours at high speed, mix well and cool.

Abstract

The invention discloses a high-temperature-resistant flame-retardant composite material, which includes component A and component B, and the dosage ratio of each component is calculated in parts by mass: component A: 80-90 parts of organic fluorine silicon modified polyurethane, 1-5 parts Parts of polytetrafluoroethylene micropowder, 1-5 parts of antimony trioxide, 5-10 parts of hexafluoropropylene trimer, component B: 5-10 parts of polycarbodiimide, 1-5 parts of hexafluoroisopropanol , 90-95 parts of hexafluoropropylene trimer, and specifically define the preparation method of organic fluorine silicon modified polyurethane. The invention also discloses its preparation method and application. The composite material of the present invention has high heat-resistant and flame-retardant properties. The composite material is sprayed on a wooden board, and the composite material is subjected to a combustion test at a high temperature of 1000°C. The flame is extinguished within 30 seconds, and no combustibles fall, reaching the flame-retardant standard V -Level 0. The composite material of the invention has better physical properties at the same time. As a paint sprayed on the wood board, the wood board has good flame retardancy, so as to meet the needs of specific occasions.

Description

technical field [0001] The invention relates to the technical field of flame retardant materials, in particular to a high temperature resistant flame retardant composite material and a preparation method and application thereof. Background technique [0002] With the development of the economy and the progress of the society, people have higher and higher requirements for the living environment, and the demand for functional materials is also stronger and stronger.
