Problems solved by technology

[0005]①Currently, most glyphosate additives are synergistic additives without thickening effect
But add alkyl glycoside surfactant in glyphosate ammonium salt synergistic system, can obviously reduce the viscosity of system, disclose a kind of glyphosate ammonium salt synergist as Chinese patent CN102396449B, this auxiliary agent consists of ten Sodium dialkylbenzene sulfonate, cetyltrimethylammonium bromide, alkyl glycoside, lecithin, silicone defoamer AF-9000 and water, the additive has a certain synergistic effect, but not It has a thickening effect, and the cost of raw materials is relatively high
[0006]②The appearance quality (viscosity, transparency, wall-hanging performance and color, etc.) of general ammonium

Abstract

The invention discloses a special thickening and efficiency-improving aid for ammonium glyphosate. The aid comprises the following components by weight: 10 to 30% of a quaternary ammonium salt cationic surface active agent, 40 to 70% of amine oxide, 2 to 5% of a short-carbon-chain alcohol solvent, 10 to 30% of a non-ionic surface active agent alkyl glycoside and 0.5 to 2% of a weakly acidic pH regulator, with the balance being water. A preparation method for the aid comprises the following steps: uniformly mixing the quaternary ammonium salt cationic surface active agent with the short-carbon-chain alcohol solvent under full stirring; then adding the alkyl amine and the weakly acidic pH regulator and carrying out uniform mixing under stirring once again; and finally adding the non-ionic surface active agent alkyl glycoside, supplementing the balancing water and carrying out uniform mixing under stirring. The special thickening and efficiency-improving aid provided in the invention has the advantages of a wide application scope, stable performance, good thickening and efficiency-improving effects, etc., and can not only effectively improve the apparent viscosity of an ammonium glyphosate water aqua, but also significantly improve the efficacy of the ammonium glyphosate water aqua.

Description

technical field [0001] The invention belongs to the technical field of agricultural surfactants, and in particular relates to a special thickening and synergistic assistant for glyphosate ammonium salt. Background technique [0002] The chemical name of glyphosate is N-(phosphonomethyl)glycine. It is a non-selective and non-residual herbicide. It is very effective against perennial root weeds and is widely used in rubber, mulberry, tea, orchards and sugarcane fields . Due to the poor solubility of glyphosate acid, glyphosate acid is generally neutralized to prepare glyphosate salt, usually ammonium salt, isopropylamine salt, potassium salt, sodium salt, dimethylamine salt, among which glyphosate ammonium salt The most widely used in the market. The main products of ammonium glyphosate are 30% ammonium glyphosate salt solution and 75% ammonium glyphosate powder. At present, the additives used in 30% glyphosate ammonium salt solution are mainly non-ionic surfactants such as...
