Embodiment 1

[0045] Smoke composition formula 1 (parts by weight): 20 parts of Dijiaheli, 22 parts of ammonium nitrate, 40 parts of corn cob, 5 parts of bentonite

[0046] Preparation Process:

[0047] 1. Sieve each raw material separately to remove the impurities;

[0048] 2. Adopt airflow crushing and supporting mixing equipment to crush various raw materials respectively;

[0049] 3. Dry the crushed raw materials in a special fire-proof drying room until moisture is removed;

[0050] 4. After measuring various raw materials separately, put them into a high-efficiency mixer and mix them evenly;

[0051] 5. After the product passes the inspection, put it into a paper bag, then put it into a polyethylene film packaging bag, and seal it.

Embodiment 2～12

[0054] The preparation process of the smoke composition of Examples 2-12 is the same as that of Example 1.

[0055] The following experimental examples are the items and methods for testing the physical properties and quality indicators of three moisture-proof and safe smoke composition compositions: Dijiaheli smoke composition, dichlorvos smoke composition, and chlorothalonil smoke composition.

experiment example 1

[0056] Experimental Example 1 Determination of Combustion Rate

[0057] Method: After burning the smoke composition, weigh it, and calculate the ratio of the smoke weight minus the burned ash weight to the smoke weight.

Abstract

The smoke agent consists of main agent 12-45 weight portions, combustion promoter 22-35 weight portions and fuel 30-40 weight portions. The combustion promoter is one or several selected from ammonium nitrate, potassium nitrate, sodium nitrate, potassium perchlorate and potassium permanganate; and the fuel is one or several selected from corn cob, cow manure powder, straw and bagasse. The smoke agent is prepared through sieving, crushing, stoving, mixing and bagging. It is safety without self combustion, low in cost and favorable to environment protection, and its package isolates moisture effectively.

Description

Technical field: [0001] The invention relates to a novel pesticide moisture-proof and safe smoke composition and a preparation method thereof. Background technique: [0002] Smoke agent is a new formulation of pesticide used to prevent and control diseases in protected areas. Its characteristic is to evenly release the drug in the form of smoke in the form of particles (0.3-2 microns in diameter) to various parts of the crops and the corners of protected spaces such as plastic greenhouses and greenhouses. [0003] General agricultural insecticides and fungicides are composed of a main agent (i.e. the original pesticide), a chemical exothermic agent (including an oxidant and a fuel used as a combustion aid) and an auxiliary agent. A good smoke agent should have a high rate of smoke formation, easy to use, easy to obtain raw materials, and low cost. [0004] If the oxidant of the smoke agent is improperly selected, it may be difficult to form smoke, or prone to spontaneous c...
