Technical Field

[0001] The invention relates to the technical field of production of anti-mite latex pillows, in particular to a production process of anti-mite latex pillows. Background Art

[0002] As people's living standards continue to improve, higher requirements are put forward for the living environment, and textiles with anti-mite function are also favored. In the past, fabrics with anti-mite function were only used in specific fields such as military and medical use, but now they have entered the lives of ordinary people, so functional fabrics such as anti-mite have also had a greater demand and market. Mites are widely present in household textiles, which can cause a series of diseases such as allergic asthma, allergic rhinitis, allergic dermatitis, eczema, hay fever, scabies, etc., causing great trouble to people's lives. Pure natural latex pillows, because the sap of the rubber tree has a certain effect of preventing the breeding of mites, but its effect of repelling mites cannot meet practical requirements, so the research and development of anti-mite latex pillows has practical value.

[0003] Studies have found that boric acid and borates can cause mites to become dehydrated, with depressions on their backs and abdomens, making them fragile and unable to reproduce; aromatic carboxylates can act on the nervous system of mites; eugenol and its derivatives have strong clove and spicy aromas, and have good repellent and killing effects on mites.

[0020] The present invention: Firstly, three composite anti-mite agents Ca are designed and synthesized using small molecule monomers with anti-mite function as raw materials, and the specific synthesis scheme is as follows:

[0021] The amino functional group of p-phenylenediamine reacts with the acyl chloride functional group of terephthaloyl chloride to form terminal acyl chloride aromatic amide; the acyl chloride functional group of terminal acyl chloride aromatic amide reacts with the amino functional group of 3-aminophenylboronic acid to form terminal phenylboronic acid aromatic amide; the boric acid group of terminal phenylboronic acid aromatic amide and the hydroxyl functional group of eugenol are reversibly bonded through a boric acid ester bond to form a composite anti-mite agent Ca1;
