preparation example 1

[0077] Preparation Example 1: Ethyl Acrylate (EA) Polymer Latex-1

[0078] A kind of zero addition polymer latex A is made by following process:

[0079] 1) 15g of sodium lauryl sulfate, 5g of ANPEO10, 5g of COPS-1, 285g of deionized water, 145g of MMA, 800g of EA, 50g of AAEM, and 5g of AA were mixed to obtain a pre-emulsion (ME);

[0080] 2) 1.6gAPS and 40g water are mixed to obtain the dripping initiator solution;

[0081] 3) 2.4gAPS and 30g water are mixed to obtain the initiator solution at the bottom of the tank;

[0082] 4) Add 0.5g of sodium lauryl sulfate and 500g of deionized water into the reactor, stir and dissolve them, and heat them to 85°C in a nitrogen environment. When the temperature in the reactor rises to 85°C, add 50g of Pre-emulsion (ME) and all the initiator solution at the bottom of the kettle are kept for 10 minutes;

[0083] 5) Control the temperature at 85°C, add the remaining pre-emulsion (ME) and the entire initiator solution dropwise at the sam...

[0086] Preparation Example 2: Butyl Acrylate (BA) Polymer Latex-2

[0087] A zero-added polymer latex-2 is prepared by the following process:

[0088] 1) 15g sodium lauryl sulfate, 285g deionized water, COPS-1 of 5g, the MMA of ANPEO10,385g of 5g, the BA of 560g, the AAEM of 50g, the AA of 5g are mixed to obtain monomer pre-emulsion (ME );

[0089] 2) 1.6gAPS and 40g water are mixed to obtain the dripping initiator solution;

[0090] 3) 2.4gAPS and 40g water are mixed to obtain the initiator solution at the bottom of the tank;

[0091] 4) 0.5g of sodium lauryl sulfate and 500g of deionized water are added to the reactor and heated to 85°C in a nitrogen environment. When the temperature in the reactor is warming up to 85°C, 50g of pre-emulsion ( ME) and the initiator solution at the bottom of the tank were incubated for 10 min;

[0092] 5) Keep the temperature at about 85°C, add the remaining pre-emulsion (ME) and the initiator solution dropwise at the same time, keep the t...

[0095] Preparation Example 3: Ethyl Acrylate (EA) Polymer Latex-3

[0096] A zero-added polymer latex-3 is prepared by the following process:

[0097] 1) 15g of sodium lauryl sulfate, 5g of COPS-1, 285g of deionized water, 145g of MMA, 800g of EA, 50g of AAEM, and 5g of AA were mixed to obtain a pre-emulsion (ME).

[0098] 2) Mix 1.6g APS and 40g water to obtain a dropwise initiator solution.

[0099] 3) Mix 2.4g APS and 40g water to obtain a tank bottom initiator solution.

[0100] 4) Add 0.5g of sodium lauryl sulfate and 500g of deionized water to the reactor and heat it to 85°C in a nitrogen atmosphere. When the temperature in the reactor rises to 85°C, add 50g of pre-emulsion (ME ) and the initiator solution at the bottom of the kettle were kept for 10 minutes.

[0101]5) Keep the temperature at about 85°C, add the remaining pre-emulsion (ME) and the initiator solution dropwise at the same time, keep the temperature for 20 minutes after the dropwise addition is complete...

Abstract

The invention discloses an interior wall paint with mosquito repelling effect. The long EO group in the polymer latex used in this kind of interior wall coating has an affinity effect with the hydrophilic mosquito repellent, so that the mosquito repellent can be released slowly, which can effectively repel mosquitoes for a long time. Also, by using EA monomers and a small amount of acetoacetate or acetoacetamide functional groups as monomers or as non-polymeric additives, the polymer latex prepared by using a nonionic emulsifier with a long EO number does not need to be added during the preparation of coatings. Coalescing aid and antifreeze, and has good scrub resistance, aldehyde removal performance and good freeze-thaw stability.

Description

technical field [0001] The invention provides an interior wall paint with long-lasting mosquito repelling effect and a preparation method thereof. Moreover, the mosquito repellent paint does not need to add film-forming aids and antifreezing agents, and is an environmentally friendly paint. Background technique [0002] For a long time, people have focused on the health and environmental protection of latex paint, but paid less attention to functional latex paint. This is because most of the current latex paint has high content of VOC and SVOC, which will affect human health. make an impact. Under the premise that healthy and environmentally friendly latex paints can be prepared, functional paints are bound to get more attention and preference from consumers. [0003] In daily life, mosquito bites bring a lot of troubles to human beings, ranging from affecting sleep and skin swelling, itching and redness, to spreading diseases and seriously endangering health. Mosquito re...
