Embodiment 1

[0066] (1) Preparation of modified papermaking waste

[0067] A certain amount of pulping black liquor prepared by the conventional caustic soda method is added with sulfuric acid to adjust the pH of the system to 3, and then dried and sieved to obtain papermaking waste. The particle size of the sieved material is 300-1000 Item. The paper-making waste is mixed with stearoyl chloride and pyridine in a high-mixer to obtain modified paper-making waste; the mass ratio of paper-making waste to stearoyl chloride is 100:5, and the mass ratio of paper-making waste to pyridine is 100: 1; The mixing temperature in the high mixer is 120°C, the mixing time is 120min, and the rotation speed is 300rpm.

[0068] (2) Preparation of masterbatch for biodegradable insect trap

[0069] The raw material composition for preparing the masterbatch of the biodegradable insect trap was added to a high-speed mixer and mixed, and the mixture was placed in a twin-screw extruder for extrusion and granulation. T...

Embodiment 2

[0076] (1) Preparation of modified papermaking waste

[0077] Sulfuric acid is added to the pulping black liquor made from a certain amount of conventional sulfate to adjust the pH of the system to 3, and then drying and sieving are performed. After sieving, the particle size of the material is 300-1000 mesh. The paper-making waste is mixed with stearoyl chloride and pyridine in a high-mixer to obtain modified paper-making waste; the mass ratio of paper-making waste to stearyl chloride is 100:10, and the mass ratio of paper-making waste to pyridine is 100: 2; The mixing temperature in the high mixer is 150°C, the mixing time is 180min, and the rotation speed is 500rpm.

[0078] (2) Preparation of masterbatch for biodegradable insect trap

[0079] The raw material composition of the master batch of the biodegradable insect trap was added to a high-speed mixer and mixed, and the mixture was placed in a twin-screw extruder for extrusion and granulation. The temperature of the first to ...

Embodiment 3

[0086] (1) Preparation of modified papermaking waste

[0087] A certain amount of pulping black liquor prepared by the conventional sulfite method is added with sulfuric acid to adjust the pH of the system to 3, and then drying and sieving are performed. After the sieving, the particle size of the material is 500-800 mesh. Then it is mixed with stearyl chloride and pyridine in a high-mixer to obtain modified papermaking waste; the mass ratio of papermaking waste to stearyl chloride is 100:20, and the mass ratio of papermaking waste to pyridine is 100:3; The mixing temperature in the high mixer is 150°C, the mixing time is 180 min, and the rotation speed is 500 rpm.

[0088] (2) Preparation of masterbatch for biodegradable insect trap

[0089] The raw material composition of the master batch for preparing the biodegradable insect trap board is added to a high-speed mixer and mixed, and the mixture is placed in a twin-screw extruder for extrusion and granulation. The temperature of th...

Abstract

The invention discloses an application of a raw material composition in preparation of a biodegradable insect trapping plate. The raw material composition comprises the following components in parts by weight: 5-20 parts of modified papermaking waste, 50-90 parts of a biodegradable resin and 1-10 parts of auxiliaries, wherein the modified papermaking waste comprises 100 parts of papermaking waste,1-50 parts of a modifier and 0.1-5 parts of a phase transfer agent, and the modifier is one or more of stearoyl chloride, acetyl chloride, benzoyl chloride, oxalyl chloride, chloroacetyl chloride andtrichloroacetyl chloride. The master batch of the biodegradable insect trapping plate and the biodegradable insect trapping plate can be completely degraded by microorganisms in the nature, so that the environment is not polluted, waste utilization can be achieved, and the cost is reduced. The modified papermaking waste is adopted, so that the compatibility of the modified papermaking waste and biodegradable resin can be effectively improved, and the tensile strength and elongation at break of the biodegradable insect trapping plate are improved. The insect trapping amount of the biodegradable insect trapping plate is obviously superior to that of a traditional PP insect trapping plate and that of a traditional PVC insect trapping plate.

Description

Technical field [0001] The invention specifically relates to the application of a raw material composition in the preparation of a biodegradable insect trap. Background technique [0002] Small pests such as thrips, whiteflies, aphids, and Liriomyza, have always been the main pests on vegetables, flowers and important cash crops. Their tiny individuals, fast reproduction speed, hidden activity, and wide host range are extremely harmful to crops. As an important physical pest control product, the pest trap board follows the green, safe, and environmentally friendly plant protection concept, and has been widely used for pest monitoring and control in the production of vegetables, flowers, and trees. 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 fruits and vegetables, and improves food quality and quality. [0003] The base material used in the existing traps is ...
