Embodiment 1

[0023] A paper-based insect trap barrier layer and its preparation steps are as follows:

[0024] Step 1: Mix 90 parts of styrene-acrylic latex, 10 parts of styrene-butadiene latex, 5 parts of wax emulsion, and 0.2 parts of defoamer emulsified silicone oil, etc. and mix together mechanically to prepare a composite emulsion. The rotation speed is 300r / min, and the mixing time is 10min.

[0025] Step 2: Add 5 parts of yellow color paste and 1.5 parts of thickener carboxymethyl cellulose, etc. into the composite emulsion prepared in step 1, wherein the rotation speed is preferably 400r / min, and the mixing time is 30min.

[0026] Step 3: Filter the composite emulsion prepared in Step 2, wherein the filter screen is a 325-mesh metal mesh to obtain the barrier layer liquid of the paper-based insect trap.

[0027] Step 4. Use a coating machine to coat the composite emulsion on both sides, wherein the oven temperature is 105°C, and the latex coating amount is 10g / m 2 , to prepare a ...

Abstract

The invention discloses a preparation method of a paper-based insect trapping board barrier layer, the preparation method comprises the following steps: selecting paperboard as an insect trapping board base material, taking water-soluble latex such as styrene-acrylic latex, styrene-butadiene latex and cationic latex as raw materials for preparing coated paper, taking water-based color paste as pigment, adjusting a proper coating amount, so that the color, the water resistance, the viscosity and the like of the prepared coated paper can meet the production requirements of products. Compared with a traditional PP insect trapping board base material, the paper-based insect trapping board base material prepared through the coating method can meet the use requirement of an insect trapping board, the problem of white pollution after PP is used can be solved, the price of the insect trapping board base material is greatly reduced, and the water absorption of paperboard is improved through the barrier layer on the paper-based surface, and the wet strength of the paperboard is improved.

Description

technical field [0001] The invention relates to the technical field of agricultural and forestry pest control, in particular to a barrier layer of a paper-based insect trap and a preparation method thereof. Background technique [0002] Small pests such as thrips, whitefly, aphids and liriomyza have always been the main pests on vegetables, flowers and important economic crops. Their tiny individuals, fast reproduction speed, hidden activities and wide host range are extremely harmful to crops. As an important physical pest control product, the insect trap has been widely used in the monitoring and control of pests in the production of vegetables, flowers, and forest fruits following the concept of green, safe, and environmentally friendly plant protection. The use of insect traps effectively reduces the use of chemical pesticides, delays the development of pest resistance, reduces pesticide residues in the environment and in fruits and vegetables, and improves food quality ...
