Problems solved by technology

[0003] The substrates used in the current insect traps are mostly PP or PVC derived from the petrochemical industry. After being discarded, there is a problem that it is not easy to degrade, causing secondary pollution to the agricultural ecological environment.
In recent years, the application of existing insect traps has become more and more extensive, and the number of uses has also increased year by year, causing more serious damage to the agricultural ecological environment

preparation example Construction

[0027] The present invention also provides a method for preparing a biodegradable paper-based insect trap, which specifically includes the following steps:

[0028] Step 1: put the styrene-butadiene latex, styrene-acrylic latex, wax emulsion and color paste into the reaction kettle and mix evenly to obtain the mixed latex. The mixing speed is 10-600rpm, the mixing time is 20-300min, and the mixing temperature is 20-150°C ;

[0029] Step 2, the mixed latex is coated twice with a single-sided coater, the drying temperature is 80°C-150°C, and the latex coating amount is 4-12g / m 2 , complete the water-blocking layer, and prepare a waterproof biodegradable paper-based substrate;

[0030] Step 3, spraying sticky shellac on both sides of the paper base substrate to form a sticky shellac layer, the coating amount of sticky shellac is 50-80g / m 2 , and then the sticky shellac layer is covered with release paper to prepare a biodegradable paper-based insect trap.

Abstract

The invention discloses a biodegradable paper-based insect trapping board and a preparation method thereof, and belongs to the technical field of pest control, the insect trapping board comprises a paper-based material, a waterproof layer, insect sticking glue layers and release paper layers, and the waterproof layer comprises 50-95 parts of styrene-butadiene latex, 5-50 parts of styrene-acrylic latex, 1-15 parts of wax emulsion and 1-10 parts of yellow color paste. The preparation method comprises the steps that the latex layers are evenly smeared on the upper face and the lower face of the paper-based material, the insect sticking glue layers are evenly smeared on the latex layers, the release paper layers are arranged on the outer sides of the insect sticking glue layers in a packaging mode, the insect trapping board is placed in a farmland or a living room, pests are driven by yellow light to migrate to the insect trapping board, and then the pests are firmly attached to the insect trapping board. The trapping effect on pests such as aphids, bemisia tabaci, flies and drosophila melanogaster is good, and the pests can be firmly stuck. The paper-based material is non-toxic and harmless, can be naturally degraded, is green and environment-friendly, conforms to the sustainable development view, and is easier to popularize, and the performance of the paper-based material can meet the requirements of production and life.

Description

technical field [0001] The invention relates to the technical field of agricultural and forestry pest control, in particular to a biodegradable paper-based insect trap and a preparation method thereof. Background technique [0002] As a large vegetable and fruit producing country, pest control is a key step in agricultural planting. Due to the extensive use of pesticides in the process of pest control, the residual chemical substances not only pollute the environment, but also endanger our health. As people pay more attention to dietary health issues, and at the same time, in order to meet the needs of the concept of green environmental protection, the planting industry has begun to use a large number of insect traps in the field to eliminate insects. It is an important means to improve the ecological balance and realize the green and sustainable development of agricultural products. It has been widely used in the monitoring and control of pests in the production of vegetabl...
