Description

Anti-mosquito fabric base material resin and preparation method and application thereof Technical Field The invention belongs to the field of special fabrics, and particularly relates to an anti-mosquito fabric, in particular to an anti-mosquito fabric base material resin, a preparation method and application thereof. Background Mosquito is the main transmission medium of dengue fever, malaria, encephalitis B and other diseases. Global dengue cases were over a million in 2024, and the death of mosquito-borne diseases was over 70 ten thousand per year with an economic loss of 30 hundred million dollars (aedes only). The traditional chemical mosquito repellent (such as the deet) has the problems of skin irritation, environmental pollution and the like, and safer protection means are urgently needed. In addition, outdoor workers in forestry, agriculture, military and the like are exposed to high-density mosquito bites (up to hundreds/cubic meter). The common clothes have large fabric pores, so that mosquitoes can easily penetrate, the air permeability is reduced due to the thickening of the clothes, and the clothes are easy to cause heat stress when being worn in summer. The existing mosquito-repellent technical routes include a mosquito repellent soaking method, a surface finishing method, a blending spinning method and the like, and although the existing mosquito-repellent technical routes have remarkable progress on the mosquito-repellent effect, the existing mosquito-repellent technical routes are found to have problems through deep analysis. Several anti-mosquito fabrics have some common problems: The durability and washing resistance of the mosquito-repellent are insufficient, and most technical schemes are difficult to consider the instant mosquito-repellent effect and long-acting property. The initial repellent rate of the fabric prepared by the mosquito repellent soaking method can reach more than 85%, but after 5 times of standard washing, the repellent rate is suddenly reduced to 40% -60%. And the traditional manufacturing process of the anti-mosquito fabric involves various environmental pollutants. The biological enrichment of the synthetic mosquito repellent (such as permethrin) leads to ecological risks, and experiments show that the water washing liquid of the permethrin fabric is only 0.15mg/L for aquatic organisms (daphnia magna) for 48h-LC 50. To achieve long lasting protection against mosquitoes, the prior art often comes at the expense of comfort. The thickness of the multilayer composite fabric reaches 0.8-1.5 mm, the air permeability is lower than 30cm < 3 >/s/cm < 2 > (the requirement of clothing in summer is more than 50cm < 3 >/s/cm < 2 >), and the risk of heat stress is caused. The existing anti-mosquito fabric has the problems of single function, performance sacrificing, short plate changing effect, good mosquito repelling effect, durability, discomfort and the like.

Preferably, the molecular weight of the UHMWPE resin is 150-200 ten thousand. Preferably, the molecular weight of the HDPE is 30-50 ten thousand. Preferably, the particle size of the mosquito-repellent microcapsule is 5-20 mu m, the core material of the mosquito-repellent microcapsule is active permethrin, and the active permethrin accounts for 20-40% of the mass of the mosquito-repellent microcapsule; The camphor leaf essential oil derivative accounts for 3 to 8 percent of the mass of the anti-mosquito resin. Preferably, the compatilizer is maleic anhydride grafted PE, the grafting rate is more than or equal to 1.2%, the antioxidant is pentaerythritol tetrakis [ beta- (3, 5-di-tert-butyl-4-hydroxyphenyl) propionate ] 1010/tri (2, 4-di-tert-butylphenyl) phosphite 168 complexing agent, and the spinning aid is calcium stearate and polyethylene glycol.
