preparation example Construction

[0025] The preparation method of surfactant among the present invention is:

[0026] First, fatty amine and ethylene oxide are used for condensation reaction in two stages. The first stage is that 2mol ethylene oxide is directly added to the two active hydrogen atoms of the amine at a certain temperature and without a catalyst; the second stage stage, at a certain temperature and under the action of a basic catalyst, add the remaining ethylene oxide to make aliphatic amine polyoxyethylene ether; Under the reaction conditions, the quaternization reaction is carried out, and the fatty amine polyoxyethylene ether diquaternary ammonium salt surfactant is obtained by the reaction, that is, dichlorinated double fatty alkyl polyoxyethylene ether biphenyl benzyl ammonium; the reaction equation is: condensation reaction; In the quaternization reaction equation, R is a C12-C18 saturated linear or branched alkyl group, and the general formula is C a h 2a+1 , where a=12~18.

Abstract

The invention provides a surfactant composition for solving serious livering of water suspension in thermal storing. The surfactant composition comprises the following components in percentage by weight: 15-20% of a first dispersing agent, 10-15% of a second dispersing agent, 15-20% of a surfactant, 5-10% of an antifreeze agent, and the balance of water. Compared with the prior art, the surfactantcomposition has the beneficial effects that the problem that pesticides are easily molten in processing and storing processes can be effectively solved; and the problem of serious layering and livering in thermal storing can also be solved.

Description

technical field [0001] The invention relates to a surfactant composition used for solving severe creaming of water suspensions during heat storage, which can be widely used in water suspension formulations of pesticides and has obvious effects on pesticides that are easy to cream and have low melting points. Background technique [0002] The water-suspending agent dispersant currently on the market has no effective effect on the original drug which is easy to paste and has a low melting point; Melting and agglomeration during storage; second, serious layering and creaming during thermal storage. The formulations that need to be solved mainly include the following: [0003] 50% triphenyltin hydroxide aqueous suspension; [0004] 50% dicyanotrope aqueous suspension concentrate; [0005] 5% emamectin benzoate + 20% indoxacarb aqueous suspension; Contents of the invention [0006] The object of the present invention is to provide a kind of surfactant composition that is us...
