Production process of antibacterial and deodorizing plastic composite materials for plastic pet houses

Abstract

The invention discloses a production process of an antibacterial and deodorizing plastic composite material for plastic pet houses, and the production process comprises the following steps: drying attapulgite clay at a temperature of 300-400 DEG C for 2-3 hours, taking out the attapulgite clay, impregnating the attapulgite clay into a saturated solution of an antibacterial agent to treat for 4-5 hours, draining off water, adding a silane coupling agent solution, and treating for 10-30 minutes in a high-speed stirrer; after the attapulgite clay is taken out, putting the attapulgite clay into a drying oven at a temperature of 120-140 DEG C to dry for 1-2 hours, and then drying for 4-5 hours at a temperature of 200 DEG C, so that attapulgite clay loaded with the antibacterial agent is obtained; mixing the attapulgite clay with a mass percentage of 0.5-2% with a plastic, and preparing an antibacterial and deodorizing plastic masterbatch by using a twin-screw extruder; and mixing the prepared antibacterial plastic masterbatch with a pure resin, and preparing an antibacterial composite material by injection molding.

Description

technical field [0001] The invention relates to a production process of an antibacterial and deodorizing plastic composite material for a plastic pet house. Background technique [0002] With the improvement of people's living standards, more and more people start to keep pets, and the use of plastic pet houses is also increasing. During the use of plastic pet houses, it is prone to odor and bacteria are easy to breed, causing pets to get sick easily and causing environmental pollution. Therefore, the antibacterial and deodorizing of plastic pet houses is a problem that must be solved in the process of raising pets. A commonly used method to improve the antibacterial properties of plastics is to add antibacterial agents to plastics or to coat antibacterial agents on the surface of plastics. The disadvantage of the surface-coated antibacterial agent is that the antibacterial agent is easy to fall off from the plastic surface and has a short service life. The advantage of di...

Problems solved by technology

The disadvantage of the surface-coated antibacterial agent is that the antibacterial agent is easy to fall off from the plastic surface, and the service life is short

The advantage of directly adding antibacterial agents to plastics is that they can be used for a long time, but most of the antibacterial agents are not easy to work because they are wrapped in plastic, and the antibacterial effect is poor; it has been reported that porous materials such as activated carbon and zeolite are used as carriers of antibacterial agents , can partially solve this problem, but antibacterial carriers such as activated carbon and zeolite are granular, and there is also the problem that the antibacterial effect of the antibacterial agent cannot be fully exerted due to being covered by plastic

In addition, the deodorization method for pet rooms is to use porous materials such as activated carbon to adsorb, but activated carbon and other materials are not easy to fix and are easily damaged by pets.
