[0048] Wherein, the novel sorbitol nucleating agent of embodiment 4 is 1,3-2,4-bis(p-methylbenzylidene)-1-allyl sorbitol, and its synthetic method comprises the following steps:

[0049] (1) The HBr alcoholic solution with a concentration of 0.5mol / L was prepared, wherein the volume percentage of ethanol was 10%; 3 parts of glucose, 2.02 parts of allyl bromide, 1.98 parts of Sn powder, and 50 parts of 0.5mo / L HBr alcoholic solution Place in the reaction kettle, stir and react at room temperature for 48h to obtain a mixed solution; add 5mol / L NaOH aqueous solution dropwise to the mixture to neutralize to pH=7, and a large amount of white precipitates are formed during the dropwise addition to obtain a suspension; Suction filtration of the suspension to remove the precipitation to obtain a filtrate; the filtrate is subjected to rotary evaporation to remove the solvent to obtain a milky white solid 1-allyl sorbitol;

[0050] (2) 3.7 parts of the milky white solid, 4.0 parts of p-...

Abstract

The invention relates to the technical field of medical tapes, and discloses a special tape for protective clothing, comprising a polypropylene base film layer and a pressure-sensitive adhesive layer, and the pressure-sensitive adhesive layer is adhered to one side of the polypropylene base film layer; The polypropylene base film layer is made of polypropylene composite material, and the polypropylene composite material, in parts by weight, includes the following components: 40-80 parts of polypropylene, 20-40 parts of modified hollow glass fiber, and 1 compatibilizer ~5 parts, 0.2-1 part of lubricant, 0.2-1 part of antioxidant, and 0.2-1 part of anti-radiation agent; wherein, anti-radiation agent comprises butylmethoxydibenzoylmethane, 4-methoxycinnamic acid- 2-ethylhexyl ester, 2-hydroxy-4-n-octyloxybenzophenone, 2,4-dihydroxybenzophenone, resorcinol monobenzoate, 2-(2-hydroxy-5 -methylphenyl) at least one of benzotriazole and benzophenone-3. This special tape has excellent radiation resistance, heat resistance and transparency.

Description

technical field [0001] The invention relates to the technical field of medical adhesive tapes, in particular to a special adhesive tape used for protective clothing. Background technique [0002] Polypropylene (PP) is a semi-crystalline thermoplastic with high impact resistance, strong mechanical properties, and resistance to various organic solvents and acid and alkali corrosion. It has a wide range of applications in the industry and is one of the common polymer materials. However, with the continuous expansion of the application of polymer materials in medical supplies, food packaging and other fields, higher requirements have been placed on the performance of polypropylene materials. For example, in order to avoid chemical residues, medical tapes made of polypropylene materials are generally sterilized by radiation or high temperature before they can be provided in medical places for consumers to use. However, the poor radiation resistance and heat resistance of ordina...
