preparation example Construction

[0044] The preparation method of described super water-resistant white succinate surfactant comprises the steps:

[0045] S101: Weigh the alkyl polyoxyethylene ether, maleic anhydride, sodium sulfite and pure water by weight for subsequent use;

[0046] S102: Put all the alkyl polyoxyethylene ethers into the polymerization reactor, raise the temperature to 100°C and dehydrate for 2 hours, then cool down to 50°C;

[0047] S103: The temperature is stably controlled at 50°C. After blowing nitrogen, all the maleic anhydride is added, replaced by vacuum blowing nitrogen for 5 times, and nitrogen is sealed until the internal pressure of the polymerization reactor is 0.05 MPa. After the addition, the temperature at the bottom of the reactor is controlled to be 50°C, the temperature at the top of the reactor was 40.2°C, and stirred for 30 minutes;

[0048] S104: Turn off the oil temperature after the nitrogen drum is heated up, and control the temperature to a preset range to obtain ...

Abstract

The invention relates to the technical field of high polymer materials, in particular to preparation and application of a super-water-whitening-resistant succinate surfactant. The super-water-whitening-resistant succinate surfactant is prepared from the following components in parts by weight: 170 to 190 parts of alkyl polyoxyethylene ether, 45 to 60 parts of maleic anhydride, 60 to 70 parts of sodium sulfite and 670 to 700 parts of pure water. The preparation method comprises the following steps: adding maleic anhydride into alkyl polyoxyethylene ether, stirring for 30 minutes, blowing nitrogen, heating to 90-95 DEG C, reacting for 3 hours, sampling, measuring the acid value to be less than 132 and the active matter to be not less than 95%, adding part of water, adding sodium sulfite, complementing the rest of water, stirring at 50-60 DEG C for half an hour, sampling, measuring the pH value to be 5.0-7.5 and the acid value to be less than 5, and carrying out qualified discharge. According to the invention, in emulsion polymerization of the ceramic tile adhesive, the advantages that the water whitening resistance of the emulsion is improved, the emulsification rate is high, and the emulsion does not contain APEO are achieved.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to the preparation and application of a super water-resistant white succinate surfactant. Background technique [0002] Tile adhesives are mainly used to paste decorative materials such as ceramic tiles, facing tiles, and floor tiles. They are widely used in decoration places such as interior and exterior walls, floors, bathrooms, and kitchens. Their main features are high bonding strength, water resistance, and water resistance. Freeze-thaw, good aging resistance and convenient construction, it is a very ideal bonding material; [0003] But the ceramic tile adhesive in the prior art is to improve water-whitening resistance, usually adds surfactant, but the surfactant in the prior art can't satisfy APEO FREE index, and does not add surfactant in order to meet APEO FREE index, It is difficult to meet the water whitening resistance, so there is an urgent need for surfactant...
