Problems solved by technology

[0003] Existing beehives are mostly made of wood or plastic material, which has poor thermal insulation effect. Therefore, it is often necessary to fill a layer of thermal insulation material inside the beehive. The existing thermal insulation material has poor thermal insulation effect, and its surface is easy to breed bacteria , resulting in large-scale death of bees, seriously affecting the use of beehives

Abstract

The invention discloses a preparation method of EPE pearl wool for swarm heat preservation, which comprises the following operation steps: (1) adding epsilon-polylysine and aminated multi-walled carbon nanotubes into deionized water, and mixing and stirring to obtain an antibacterial agent; (2) adding shellac into an ethanol aqueous solution until the shellac is completely dissolved, adding the antibacterial agent into the solution, and performing ultrasonic water bath to obtain a modified antibacterial agent; (3) uniformly mixing and stirring coconut shell powder, white carbon black and diatomite, and adding an internal lubricant into the mixture to obtain a thermal insulation filler; and (4) feeding a modified polyethylene master batch, the modified antibacterial agent and the thermal insulation filler into a foaming machine for heating treatment, then adding a foaming agent to form a porous structure, and performing extruding, cooling, extending, and finally rolling to obtain the EPE pearl wool for swarm heat preservation. The prepared EPE pearl wool for swarm heat preservation has excellent heat preservation performance and excellent antibacterial performance, and bacteria canbe effectively prevented from breeding and reproducing on the surface of the EPE pearl wool.

Description

Technical field [0001] The invention relates to the technical field of bee colony insulation materials, in particular to a preparation method of EPE pearl cotton for bee colony insulation. Background technique [0002] Beehives are the most basic equipment in the breeding and management of bee colonies. As a fixed place for bee colony life, beehive plays an important role in bee development and colony reproduction. Bees can maintain relatively stable environmental conditions in their hive, and they can actively regulate temperature, humidity, gas metabolism and nutrition. The development process of bees is greatly affected by external temperature, humidity, light, etc., and temperature is an important factor affecting the development of bees. Bees are fully metamorphic insects, which develop into adults through eggs, larvae, and pupae. According to current research, it is generally considered that the temperature zone for honeybee egg development is 30-38℃, and the optimum tem...
