Embodiment 1

[0018] In the 500L reactor, drop into 180kg emulsifier OP-10, 120kg emulsifier calcium dodecylbenzene sulfonate, 12kg dimethylformamide and stir to form a composite emulsifier for subsequent use; in the 1000L reactor, drop 300kg of bamboo tar, Dimethylformamide 100kg stirs, and after all dissolving, slowly drop into 100kg standby composite emulsifier again, stir evenly, the finished product 60% bamboo tar emulsifiable oil is ready.

Embodiment 2

[0020] Put 50kg of xylene into a 1000L reactor, and slowly add 450kg of wood tar (wood tar) under constant stirring until it is completely dissolved to obtain liquid A; put 380kg of water into another 1000L reactor, and then add 25kg of propane Alcohol, 20kg emulsifier OP-10, 10kg emulsifier calcium dodecylbenzenesulfonate, 3k calcium lignosulfonate and fully stir to obtain liquid B; take 200kg liquid B and disperse and emulsify it into a uniform Disperse the emulsion, and then slowly add 200kg of A liquid under the situation of constant stirring, and fully stir to obtain the final product 45% wood tar water emulsion.

Embodiment 3

[0022] 40kg of grass tar (rice straw), 4kg of calcium lignosulfonate, 10kg of OP-10, 1kg of silicon dioxide, 3kg of ethylene glycol, continuously add 42kg of water, continuously stir and pulverize in a wet colloid mill until the fineness is 2-5μm , The finished product, 40% grass tar water dispersant.

Abstract

The invention provides an acarid-killing agent, wherein the agent comprises biomass gasified asphalt 5-90% by weight. The agent has good effect in eradicating pest such as Panonychus citri Mcgregor.

Description

technical field [0001] The invention relates to an acaricide, in particular to an acaricide containing biomass gasification tar. Background technique [0002] Biomass gasification tar is a dark brown oily substance condensed at room temperature from the gas collected after pyrolysis of plant materials and their processing residues. At present, bamboo tar, wood tar and grass tar mainly exist. "Biomass gasification tar" in the present invention includes bamboo tar (a by-product obtained by high-temperature pyrolysis of bamboo processing residues), wood tar (a by-product obtained by high-temperature pyrolysis of wood processing residues and fruit shells) products) and grass tar (referring to the by-products obtained by high temperature pyrolysis of herbs, crop straw and crop chaff). At present, in the process of processing bamboo, wood and straw into corresponding bamboo charcoal, charcoal and peat, due to the use of modern machinery for efficient prod...
