Problems solved by technology

Most of the sticky shellacs currently used contain some non-environment-friendly raw materials, which are highly toxic and have an unpleasant smell, which is difficult to adapt to environmental protection requirements (CN1067255A; CN1911012A). The compatibility of each component in the adopted formula is poor (CN1559207A; CN1847354A; CN1911012A), and it is easy to separate phases, resulting in poor stickiness of the final sticky shellac; and it is easy to flow and fall off under short-term sun exposure and rain washing , can not stick to pests for a long time, need to repeatedly glue and other shortcomings

Embodiment 1

[0011] Put 100 grams of low-molecular-weight polybutene, 20 grams of high-molecular-weight polybutene, 10 grams of β-pinene resin, and 0.3 grams of antioxidant DTBH into a container, heat to 120°C to melt the raw materials and keep stirring until Mix evenly, stop heating, continue to stir and cool to room temperature to obtain sticky shellac. The sticky shellac has a rotational viscosity of 92 Pa·s at 30°C. It is suitable for preventing and controlling pests crawling along tree trunks in agriculture and forestry. How to use: Peel off the old bark of the trunk at a distance of 40cm from the ground, first stick a closed tape ring on the smooth place with plastic tape, and then apply the sticky shellac evenly on the tape, or directly coat the closed rubber ring on the trunk .

Embodiment 2

[0013] Put 100 grams of low-molecular-weight polybutene, 8 grams of petroleum resin, 20 grams of starch, and 10.3 grams of antioxidant B1 into a container, heat to 100°C to melt the raw materials and keep stirring until they are evenly mixed, then stop heating. Continue to stir and cool to room temperature to obtain sticky shellac. The sticky shellac has a rotational viscosity of 78 Pa·s at 40°C. It is suitable for preventing and controlling pests crawling along tree trunks in agriculture and forestry. Concrete method of use: with embodiment 1.

Embodiment 3

[0015] Put 100 grams of low-molecular-weight polybutene, 80 grams of β-pinene resin, and 10.3 grams of antioxidant B11 into a container, heat to 150°C to melt the raw materials and keep stirring until they are evenly mixed, stop heating, and continue Stir and cool to room temperature to obtain sticky shellac. The sticky shellac has a rotational viscosity of 50 Pa·s at 80° C. and does not flow under normal use temperature. It is suitable for preventing and controlling flying pests in forestry and agricultural greenhouses. How to use: Apply the sticky insect glue to the strip board and hang it in the forest or in the greenhouse. Or apply the sticky insect glue on a colored strip, and then hang it in the forest or in a greenhouse, which can play a very good sticky insect effect.

Abstract

The invention relates to a preparation and application method for an environmentally friendly high-efficiency insect sticker. The insect sticker is mainly characterized in that: the insect sticker is prepared from a polybutene with a high molecular weight, a polybutene with a low molecular weight, additives and thickeners which are mixed. The additives comprise vegetable oil, starch, cellulose, bergmeal, etc. The thickeners comprise a petroleum resin, a beta-pinene resin, a cumar resin, etc. The adhesive has a capacity of adhering insects without environmental pollution. The insect sticker is suitable for preventing and controlling all forest and fruit tree insets migrating up and down along a trunk. The insect sticker can also be applied to prevent and control pests in plastic tents.

Description

Technical field: [0001] The invention belongs to the field of chemical industry, and in particular relates to a synthesis method of environment-friendly sticky shellac. It is suitable for controlling forest, fruit tree and agricultural pests that migrate up and down the trunk. Background technique: [0002] At present, agriculture and forestry mainly use broad-spectrum chemical pesticides as the main means to prevent and control diseases and insect pests. As a result, the resistance of diseases and insect pests has increased, a large number of natural enemy resources of pests have been killed by mistake, and there are too many pesticide residues in fruits and vegetables, causing great economic losses. It pollutes the environment and endangers health. Therefore, the use of green pesticides and physical measures should be advocated in the prevention and control of agricultural and forestry pests. [0003] Due to the relatively high cost of using green pesticides, physical me...
