Embodiment 1

[0032] The preparation method of absorbing aldehyde emulsion, comprises the steps:

[0033] 1) Mix 15% methyl methacrylate, 11.5% styrene, 20% n-butyl acrylate, 1% functional monomer and 2% emulsifier for pre-emulsification to obtain pre-emulsified monomer;

[0034] 2) Put 50% of water and 0.08% of emulsifier into the reaction kettle, stir, and after heating up to 82-85°C, add 0.21% of initiator and 5% of pre-emulsified monomer to carry out seed polymerization, and react for 10 -12min; raise the temperature to 84-87°C, add 0.09% initiator and the remaining pre-emulsified monomer dropwise to the reaction system, the dropping time is 3.5-4.0h, and keep warm for 1.5-2.0h after the dropping is completed ; Add 0.12% initiator to the reaction system to eliminate residual monomers and keep the temperature for 60-90min.

Embodiment 2

[0036] The preparation method of absorbing aldehyde emulsion, comprises the steps:

[0037] 1) Mix 15% methyl methacrylate, 11% styrene, 20% n-butyl acrylate, 1.5% functional monomer and 2% emulsifier for pre-emulsification to obtain pre-emulsified monomer;

[0038] 2) Put 50% water and 0.08% emulsifier into the reaction kettle, stir, and after heating up to 82-85°C, add 0.21% initiator and 3% pre-emulsified monomer to carry out seed polymerization, and react for 10 -12min; raise the temperature to 84-87°C, add 0.09% initiator and the remaining pre-emulsified monomer dropwise to the reaction system, the dropping time is 3.5-4.0h, and keep warm for 1.5-2.0h after the dropping is completed ; Add 0.12% initiator to the reaction system to eliminate residual monomers and keep the temperature for 60-90min.

Embodiment 3

[0040] The preparation method of absorbing aldehyde emulsion, comprises the steps:

[0041] 1) Mix 15% methyl methacrylate, 10.5% styrene, 20% n-butyl acrylate, 2% functional monomer and 2% emulsifier for pre-emulsification to obtain pre-emulsified monomer;

[0042] 2) Put 50% water and 0.08% emulsifier into the reaction kettle, stir, and after heating up to 82-85°C, add 0.21% initiator and 8% pre-emulsified monomer to carry out seed polymerization, and react for 10 -12min; raise the temperature to 84-87°C, add 0.09% initiator and the remaining pre-emulsified monomer dropwise to the reaction system, the dropping time is 3.5-4.0h, and keep warm for 1.5-2.0h after the dropping is completed ; Add 0.12% initiator to the reaction system to eliminate residual monomers and keep the temperature for 60-90min.

Abstract

The invention discloses a formaldehyde adsorption emulsion and a preparation method thereof. The formaldehyde adsorption emulsion is prepared from methyl methacrylate, styrene, n-butyl acrylate, functional monomers, an emulsifying agent, an initiating agent and water. The formaldehyde adsorption emulsion has the excellent function of adsorbing formaldehyde, can be applied to preparation of indoor decoration coatings, has the effect of green and environmental protection and has the advantage of decreasing the indoor formaldehyde content.

Description

technical field [0001] The invention relates to the field of emulsions, more specifically, the invention relates to an aldehyde-absorbing emulsion and a preparation method thereof. Background technique [0002] At present, a large number of paints used in the interior wall decoration of buildings on the market contain formaldehyde, which makes the decorated room full of pungent smell. If you stay for a long time, people will have dizziness, dazzling, sore throat, chest tightness and other adverse reactions. In severe cases, it may even cause convulsions and coma, damage the liver, kidneys, brain and nervous system, and cause serious consequences such as memory loss. In addition, indoor decoration materials and furniture will contain some formaldehyde. When the amount of formaldehyde in the room is 0.1%, there will be peculiar smell and discomfort; 0.5% can stimulate the eyes and cause tears; 0.6% can cause throat discomfort or pain; Nausea, vomiting, cough, chest tightness,...
