Embodiment Construction

[0036] Carry out grafting method synthesis eight 3-chloropropyl POSS / polyethylene glycol monomethyl ether surfactants with polyethylene glycol monomethyl ether, eight 3-chloropropyl POSS as example, non-limiting embodiment is described as follows:

[0037] 1) Under acidic or alkaline conditions, 3-chloropropyltrimethoxysilane is hydrolyzed, condensed, filtered, and dried to obtain eighth 3-chloropropyl POSS.

[0038] 2) Put polyethylene glycol monomethyl ether (77.22mg) and alkali metal (sodium, excess) into a 50ml reactor, stir and reflux overnight in an oil bath at 70°C. Remove the supernatant and set aside.

[0039]3) Slowly add octa-3-chloropropyl POSS (10.00 mg) dropwise to the sodium methylpolyethylene glycol solution, and stir at room temperature for 3 hours. Then the product was centrifuged to remove insoluble matter, then the solvent was evaporated by rotary evaporation, and the product was obtained by drying.

Abstract

The invention relates to a nonionic aqueous POSS-based polymer surfactant which is a polymer obtained by grafting cage polyhedral oligomeric silsesquioxane 3-chloropropyl POSS with methoxy polyethylene glycol or polyethylene glycol and is shown as the following formula. The polymer has good weather resisting property, stability and resistance, can effectively reduce the surface ability of the solution and improve the dispersibility of the cement, and is an excellent nonionic surfactant.

Description

1. Technical field [0001] The invention relates to a silicone surfactant, in particular to a nonionic silicone surfactant, specifically a nonionic water-based POSS-based polymer surfactant. 2. Background technology [0002] With the development of new silicone materials, silicone surfactants have attracted widespread interest as a new type of surfactant. Silicone surfactants are widely used due to their excellent wettability, defoaming, low foaming, temperature resistance, climate change resistance, non-toxic, non-corrosive and physiological inertness. According to the chemical properties of the hydrophilic groups in the chemical structure, silicone surfactants can be divided into four categories: nonionic, cationic, anionic and amphoteric. Among them, non-ionic surfactants are the most researched and most widely used. The current synthesis of nonionic silicone surfactants is mainly to introduce hydrophilic groups into the side chains or chain ends of network or chain poly...
