Problems solved by technology

There are two problems in this way: 1. Permethrin is a kind of insecticide, and its mode of action is mainly based on contact killing and stomach poisoning. It must be touched to kill mosquitoes, and the efficiency is low, and it may be harmful to people. Adverse effects; 2. Directly print permethrin on the surface of synthetic leather. During the processing, it is easy to evaporate into the environment together with solvents (including water), and the amount remaining on the surface of synthetic leather is extremely limited.

Abstract

The invention discloses slurry with a mosquito repelling effect, polyurethane synthetic leather and a preparation method of the polyurethane synthetic leather. A mosquito repellent agent is subjectedto slow release treatment, the retention amount of the mosquito repellent agent in the synthetic leather is increased, and the mosquito repelling effect can be ensured while the mosquito repelling effect is ensured to be long-lasing and effective. Meanwhile, a silicon-based mesoporous material is adopted during slow-release treatment, so that the slow-release effect of the mosquito repellent agentis ensured, and the wear-resistant effect of the polyurethane synthetic leather can be improved. Furthermore, in the prevention of agglomeration of the silicon-based mesoporous material, cis-13-docosenamide and other scattering agent are adopted, so that the agglomeration of the silicon-based mesoporous material is obviously improved and it is ensured that the mosquito repellent agent is distributed on the polyurethane synthetic leather. Therefore, the performance requirements of synthetic leather on durable mosquito repelling and wear resistance are met, and a wide application prospect is achieved.

Description

technical field [0001] The invention relates to a slurry with mosquito repelling effect, polyurethane synthetic leather and a preparation method thereof, belonging to the technical field of polyurethane synthetic leather. Background technique [0002] Compared with other synthetic leathers, polyurethane synthetic leather has obvious advantages in terms of wear resistance, softness, and genuine leather feel. It is one of the most important synthetic leathers at present. fields have been widely applied. [0003] However, in the field of automotive interior, sofa, upholstery and shoe materials where polyurethane synthetic leather is used, mosquitoes are often infested in summer, and at the same time, it is easy to cause the spread of some diseases (such as dengue fever). If a kind of polyurethane synthetic leather with mosquito repellent effect can be invented, it can effectively prevent the bite of mosquitoes and prevent the transmission of some diseases. [0004] At present...
