Problems solved by technology

[0005] The more effective removal substances in research reports such as the removal of formaldehyde are hydrazide compounds. Hydrazide compounds tend to exist or produce hydrazine hydrate during storage and use, which is highly toxic.

Embodiment 1

[0041] A VOC remover for composite fabrics for vehicles, which is added in the reaction kettle in sequence according to the weight ratio and order of the following raw materials, and is prepared under stirring conditions:

[0042]First add 73% water, 10% N-(2-aminoethyl)-1,3-propanediamine, 3% succinimide and PEG-200: 2% to the reactor in order, and stir evenly , slowly add in sequence: 4% butane tetracarboxylic acid, 1% maleic acid and 1% 2,3-dihydroxysuccinic acid. After the addition is completed, continue to stir for 20 minutes at room temperature, and then add 1% oleyl alcohol Polyoxyethylene ether OV-10 and 0.5% fatty alcohol polyoxyalkyl ether are used as emulsifying and dispersing agents, stirred to make it a stable and uniform solution, and finally 1.5% ammonium sulfate is added as a pH buffer regulator, and stirred evenly to prepare Taste.

[0043] The VOC remover product produced in this example is a colorless transparent liquid with a specific gravity of 1.082 g / ml...

Embodiment 2

[0046] A kind of VOC remover of composite fabric for automobiles, similar to Example 1, according to the weight ratio and order of the following raw materials, prepared under stirring conditions:

[0047] Add water 69.5%, N,N'-bis(3-aminopropyl) ethylenediamine 10%, polyacrylamide 3%, PEG-200: 8% in sequence in the reaction kettle, stir well, then slowly add butane Tetracarboxylic acid 5%, continue to stir after the addition is complete, react at room temperature for 20 minutes, then add 3% isomeric tridecanol polyoxyethylene ether E-1308 as an emulsifying dispersant, stir to make it a stable and uniform solution, and finally add 1.5 % ammonium sulfate is used as a pH buffer regulator, and it is evenly stirred.

Abstract

The invention relates to a VOC remover of a composite fabric for vehicles, which is used for treating and removing VOC gases such as formaldehyde, acetaldehyde, benzene, styrene and the like generatedin the production and processing processes of interior fabrics for vehicles. The raw materials in terms of mass percentage include the follows of: 10% to 20% of diamine compound, 3% to 8% of amide compound, 2% to 15% of PEG, 5% to 10% of carboxylic acid, 0 to 3% of emulsifying and dispersing agent, 1 % to 3% of PH buffer conditioning agent and 46% to 76% of water. The invention also provides a preparation method and a use method. The VOC remover of the composite fabric for vehicles disclosed by the invention has a significant removal effect on the VOC produced by the composite fabrics for vehicles, meets the VOC limit requirements of interior composite fabrics for vehicles required by various automotive brands and national standards, has the ability of continuous reaction, and has certainhelp for removing VOC released by other materials in the vehicle. The VOC remover of the composite fabric for vehicles disclosed by the invention has good stability, convenient use, no other negativeeffect on processed objects, low application cost and good application prospects.

Description

technical field [0001] The invention relates to the technical field of textile chemical industry, and is a VOC remover for composite fabrics for vehicles, which is used for controlling and removing VOC gases such as formaldehyde, acetaldehyde, benzene, styrene and the like generated during the production and processing of interior fabrics for vehicles. Background technique [0002] The pollution source that affects the air quality in the car is the release of harmful gases from the materials in the car, such as the volatilization of harmful organic compounds in the car interior, cushions, carpets, seat covers, seat foam, ceiling, heat insulation cotton and other component materials, causing the air in the car Low-quality pollutants are mainly volatile organic compounds (Volatile Organic Compounds), or VOCs, which mainly contain aldehydes such as formaldehyde and acetaldehyde, and harmful substances such as benzene compounds such as benzene, toluene, and styrene. [0003] The...
