Embodiment 1

[0020] Mix 3 mL of 8 mg / mL graphene oxide with 4.5 mg of multi-walled carbon nanotubes to form a graphene oxide-multi-walled carbon nanotubes composite, and dry it in a freeze dryer at -40°C for 12 hours; The dried composite is subjected to self-propagating combustion reduction to form a composite of reduced graphene oxide-multi-walled carbon nanotubes; the polypropylene (PP) homopolymer resin and copolymer resin with a mass ratio of 3:7 are mixed, and then Add the composite of reduced graphene oxide-multi-walled carbon nanotubes and flame retardant QB–PN4 to it, and then blow it out through a film blowing machine at an extrusion temperature of 185°C and a speed of 5m / min to form a barrier film; the formed layer 1. The barrier film and the skeleton layer are heat-pressed by a high-pressure heat press machine with a hot-melt adhesive film at a temperature of 125° C. for 5 s to obtain a fabric, and the fabric is processed into a raincoat, and a raincoat is obtained after packagin...

Abstract

The invention discloses a method for preparing protective clothing for spraying pesticides. The preparation process is as follows: uniformly mixing graphene oxide and multi-wall carbon nanotubes to form a graphene oxide-multi-wall carbon nanotube composite; drying the composite Post-reduction to form a compound of reduced graphene oxide-multi-walled carbon nanotubes; form a mixture of polypropylene (PP) homopolymer resin and copolymer resin; compound and flame retardant of reduced graphene oxide-multi-walled carbon nanotubes Add the above-mentioned mixture and mix evenly, and blow it out with a film blowing machine to form a barrier film; heat-press the forming layer, the barrier film and the skeleton layer in the form of a hot-melt adhesive film through a high-pressure heat press machine to obtain a fabric, process the fabric into a raincoat, and pack Promptly get a kind of protective clothing for spraying pesticide afterward. The protective clothing for spraying pesticides prepared by the process of the invention has good performance, good moisture permeability, air permeability, acid resistance, alkali resistance and pesticide permeability resistance.

Description

technical field [0001] The invention belongs to the technical field of protective clothing preparation, and in particular relates to a method for preparing protective clothing for spraying pesticides. Background technique [0002] my country is a large agricultural country. Pesticides and chemical fertilizers are used in the management of crops. If there is no certain safety protection when spraying pesticides, it is easy to cause pesticides to drip on the skin, resulting in direct contact or pollution between the pesticide liquid and human skin. , affecting the health of farmers. To prevent this process from happening, that is, to have the characteristics of repelling pesticides, this is the basic functional requirement of protective clothing for pesticide operations. Since the pesticide liquid may be water-solvent or oil-solvent, and has a certain acidity and alkalinity, this requires that the protective fabric should be Oil and water repellent, and acid and alkali resista...
