[0079] Preparation Example 1: Polymer Latex-1

[0080] A zero-added polymer latex-1 is prepared by the following process:

[0081] 1) Mix 6.6g of sodium lauryl sulfate, 5g of ANPEO10, 4g of COPS-1, 280g of deionized water, 145g of MMA, 800g of EA, 40g of AAEM, and 5g of AA to obtain a pre-emulsion (ME) ;

[0082] 2) 2gAPS and 45g water are mixed to obtain the dripping initiator solution;

[0083] 3) 3gAPS and 45g water are mixed to obtain the initiator solution at the bottom of the tank;

[0084] 4) Add 0.4g of sodium lauryl sulfate and 511g of deionized water into the reactor, stir and dissolve them fully 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;

[0085] 5) Control the temperature at 85°C, add the remaining pre-emulsion (ME) and the entire initiator solution dropwise at the same time, keep the temperatu...

Abstract

The invention discloses an interior wall coating with lasting fragrance. An EO group in used polymer latex and hydrophilic perfume form a strong hydrogen bond, so that the perfume is slowly released.The interior wall coating can keep fragrance for a long time and does not need to use a perfume carrier. An EA monomer and other polymerized or non-polymerized vinyl monomers are used in cooperation with the polymer latex prepared by using a nonionic emulsifier with the long EO number, so that a coalescing agent and an anti-freezing agent do not need to be added when the water-based coating is prepared. The fragrant coating is especially suitable for being used as a sleep-aiding and air-purifying coating in bedrooms, and is safe and non-irritant.

Description

technical field [0001] The invention discloses an interior wall paint with long-lasting fragrance and a preparation method thereof. The interior wall paint uses a polymer latex containing ethyl acrylate monomer with zero addition and low odor. There is no need to add coalescents and antifreezes in the formula, and the scented paint is especially suitable for sleep aids and air purification paints in bedrooms, which is safe and non-irritating. Background technique [0002] For a long time, people have mainly paid attention to the health and environmental protection of latex paint, but paid less attention to the functionality of latex paint. This is because most of the current latex paint has high content of VOC and SVOC, which has a great impact on human health. big impact. Under the premise that healthy, environmentally friendly and low-odor latex paints can be prepared, functional paints are bound to get more attention and use from consumers, so as to meet people's increas...
