The invention discloses a multifunctional protective suit. The multifunctional protective suit comprises a coat, a hood and trousers, which are connected integrally. The back of the coat is integrally connected with a backpack capable of containing air bottles; a tightening band is arranged on the hood, and a protective block is arranged on the front part of the hood; rapid-pulling tightening buckles are arranged on the upper part, the lower part, the left part and the right part of the backpack; openings are formed in the left side and the right side of the lower part of the backpack; a waistband is arranged at the joint of the coat and the trousers, and penetrates through the openings; the outer layer of shell fabrics of the multifunctional protective suit is coated with high-temperature-resistant silica gel. The multifunctional protective suit disclosed by the invention is convenient to wear and high in sealing performance; the outer layer is coated with the high-temperature-resistant silica gel, so that the finished clothing has the prosperities of high temperature resistance, watertightness, abrasion resistance, folding resistance, static electricity resistance and the like.

The invention discloses a super-folding-resistant nano-cellulose film and a preparation method thereof, belonging to the field of biopolymer materials. The preparation method is as follows: (1) carboxymethylation modification of cellulose fibers; (2) adding water to disperse the carboxymethylation-modified fibers, and then undergoing high-pressure homogeneous treatment to obtain nano-cellulose fibers; ( 3) After diluting the nanocellulose fibers with water, add them to a petri dish to evaporate and dry to obtain a super-folding-resistant nanocellulose film. The nanocellulose film of the present invention has excellent physical properties due to the high degree of polymerization and length of the fiber maintained during the preparation process, the number of foldings is 20000-40000 times, the tensile strength is 150-220 MPa, and the light transmittance is >90%. , and has good thermal stability (the initial thermal degradation temperature is above 250°C), and the yellowing value (ΔYI) is less than 3% when heated at 150°C for 20 minutes. Therefore, it has broad application prospects in the fields of energy and electronic devices.

The invention provides a method for utilizing phosphogypsum, the method comprising steps: S1: drying the phosphogypsum at 150-180°C for 5-25 minutes, and then directly calcining the phosphogypsum at 500-600°C for 1-2 Minutes later, modified phosphogypsum is formed; S2: cooling the modified phosphogypsum; S3: removing toxic impurities in the modified phosphogypsum; and S4: mixing the modified phosphogypsum with polyethylene to form a film layer, and the modified phosphogypsum The ratio of polyethylene is 85:15. The method further includes coating a coating layer on one side or both sides of the film layer to form a phosphogypsum film, and the phosphogypsum film can be further made into wallpaper, environmentally friendly paper, packaging materials, composite films and phosphogypsum composite profiles, etc., which utilize It can fundamentally solve the problem of phosphogypsum occupying land resources and causing serious pollution.

The invention discloses a manufacturing method for hydrolysis-resistant clothing leather. The method comprises the steps of mixing 5-10 kg of dimethyl formamide and 0.5-2 kg color paste uniformly; filtering the mixture; adding 100-120 kg of dimethyl formamide and 20-30 kg of wood powder to the above mixture, stirring uniformly and swelling; adding 100 kg of a polyurethane wet resin, stirring uniformly, defoaming and coating the obtained mixture on the textile fabric fiber; immersing in a solution of 18-22% dimethyl formamide to make the mixture solidified, squeezing water, washing with water and drying to obtain a wet base; mixing 100 kg of polyurethane dry resin, 10-20 kg of dimethyl formamide, 10-15 kg of butanone, 15-20 kg of toluene, 0.5-1.0 kg of an auxiliary agent and 3-5 kg of a toner uniformly and coating the obtained mixture on release paper to obtain a dry veneer; adhering the wet base to the dry veneer, drying, separating from the release paper, washing with a water graining machine and drying. The obtained product has the effects of hydrolysis resistance, cold resistance and folding resistance, and can effectively prolong service life of the leather.
