Problems solved by technology

[0003] In the preparation process of cross-linked acrylate polymer emulsion, commonly used emulsifiers are dodecylbenzenesulfonate anionic surfactants, alkylphenol polyoxyethylene ether nonionic surfactants or their mixtures, but due to They have poor biodegradability and are more polluting to the environment
Therefore, the application of this type of surfactant in the preparation of cross-linked acrylate polymer emulsion is limited

Embodiment 1

[0036] In a 250mL four-neck flask equipped with a stirrer, reflux condenser, and dropping funnel, add 0.50g sodium myristoyl sarcosinate, 1.00g alkyl polyglycoside, 1.05g sodium bicarbonate and 60.00g deionized water , stirred and heated to 80°C in a water bath. Add 10% of the mixed monomer and 10% of the initiator solution dropwise within 15 minutes, and continue to keep warm for 15 minutes after the dropwise addition is completed. Then the remaining initiator emulsion and mixed monomers were added dropwise into the four-necked flask within 3.0 hours. After the dropwise addition was completed, the temperature was raised to 90° C., and the temperature was continued for 40 minutes. The temperature was lowered to 40°C, the pH value was adjusted with ammonia water, and the environmentally friendly polymer emulsion was obtained after filtering and discharging. Wherein the composition of the mixed monomer is 30.00g of butyl acrylate, 22.50g of methyl methacrylate, 3.20g of hydroxy...

Abstract

The invention relates to an environmentally-friendly cross-linked acrylate polymer emulsion and a preparation method thereof. The emulsion consists of six main components through semicontinuous seeded emulsion polymerization, is fine and smooth in appearance and is a blue-fluorescent semitransparent emulsion, a pH value is 7.5+/-0.5, the solid content is 30-50%, the emulsion particle diameter is 50-100 nanometers, and the polymer emulsion has good film-forming property and adhesion after film forming at the 80 DEG C temperature. The environmentally-friendly cross-linked acrylate polymer emulsion has the advantages that due to the fact that an amino acid based anionic surface active agent and an alkyl polyglucoside non-ionic surface active agent both have excellent biodegradability and environmental protection effect and are used for replacing commonly-used alkylphenol polyoxyethylene ether and an alkylbenzene sulfonate surface active agent having poor biodegradability, the environmentally-friendly cross-linked acrylate polymer emulsion is more environmentally-friendly, and the demand for the performances of the emulsion is met.

Description

technical field [0001] The invention relates to an environment-friendly cross-linked acrylate polymer emulsion and a preparation method thereof. The polymer emulsion can be used in industrial fields such as paint, papermaking, textile, adhesive and ink. Background technique [0002] The cross-linked acrylate polymer emulsion not only has good film-forming properties, adhesion, aging resistance, light resistance, weather resistance, corrosion resistance, low price and simple synthesis process, but also has the advantages of introducing The functional group that can realize cross-linking makes it cross-linked during film formation to form a three-dimensional network structure, which overcomes the poor properties of conventional acrylate emulsion coatings such as anti-adhesion, stain resistance, solvent resistance, and heat resistance. Therefore, it is widely used as coating film-forming agent, textile printing and dyeing adhesive, daily chemical industry, chemical power supply...
