Embodiment 1

[0021] In 0.1L of magnesium chloride absolute ethanol solution with a concentration of 0.4mol / L, add 5ml of dispersant polyethylene glycol and 0.015mol of acetic acid, place in a constant temperature water bath at 60°C and mix evenly, under continuous magnetic stirring, slowly add ammonia water and Anhydrous ethanol mixed solution, a white precipitate is formed. After the dropwise addition was completed, the temperature was maintained to continue the reaction for a period of time, the precipitate was filtered, washed and then vacuum-dried to obtain a white precursor. Calcined at 550°C for 2 hours after grinding to obtain nano magnesium oxide powder. The polyester / vinylon blended ripstop fabric that has been treated for water repellency and oil repellency is used as the outer layer, 35g / m 2 The polypropylene melt-blown non-woven fabric is used as the middle layer, and the mesh lining is used as the inner layer. The prepared nano-magnesium oxide is added to the middle of the th...

Embodiment 2

[0023] In 0.1L magnesium chloride absolute ethanol solution with a concentration of 0.2mol / L, add 10ml dispersant polyethylene glycol and 0.01mol acetic acid, place in a constant temperature water bath at 60°C and mix evenly, under continuous magnetic stirring, slowly add ammonia water and Anhydrous ethanol mixed solution, a white precipitate is formed. After the dropwise addition, keep the temperature to continue the reaction for a period of time, and let stand at room temperature for 8h. The precipitate was filtered, washed and dried in vacuum to obtain a white precursor. After grinding, it was calcined at 550°C for 2 hours to obtain nano-magnesia powder. The polyester / vinylon blended ripstop cloth that has been waterproof and oil-repellent is used as the outer layer, the polytetrafluoroethylene composite film is the middle layer, and the mesh lining is the inner layer. The prepared nano-magnesium oxide is added to the middle layer of the three layers for layering. Prepara...

Abstract

The invention belongs to the field of functional composite materials, and relates to a method for preparing anti-tearing biochemical protective clothes with antibacterial function. The method comprises the following steps of: preparing nano magnesium oxide; selecting a kind of anti-tearing cloth, and performing waterproof oil repellent finishing on the anti-tearing cloth; selecting the anti-tearing cloth subjected to the waterproof oil repellent finishing as an outer supporting layer, selecting materials for a middle filter layer and a lining, adding 5 to 25g / m<2> of nano magnesium oxide among the outer supporting layer, the middle filter layer and the lining, and preparing the three layers of materials and the nano magnesium oxide into a biochemical protective composite material by hot pressing and sticking; and preparing the biochemical protective composite material into the integral protective clothes, and performing hot joint at the seams. The invention simultaneously provides the biochemical protective clothes prepared by adopting the method. The chemical substance degradation performance and the antibacterial performance of the prepared protective clothes are improved, and the comfortableness of a wearer is improved on the premise of ensuring excellent biochemical protective effect.

Description

technical field [0001] The invention relates to a tear-resistant biochemical protective composite material and protective clothing with antibacterial function, belonging to the field of functional composite materials. Background technique [0002] At present, conventional protective clothing on the market is usually divided into insulating protective clothing, breathable and semi-breathable protective clothing. Conventional insulating protective clothing has the disadvantage of being impervious to moisture, which has a certain negative impact on the physiology and psychology of the wearer; although there are many types of breathable and semi-breathable protective clothing, their protective performance is generally low and their limitations are large. Breathable and semi-breathable protective clothing are more comfortable than isolated and selectively permeable protective clothing, but their protection is relatively poor. Nowadays, in order to solve the contradiction between...
