Disclosed is a composite gel electrolyte film for a secondary battery, which has improved ion conductivity and excellent ignition resistance, while being insusceptible to coloration. Specifically disclosed is a composite gel electrolyte film for a secondary battery, which is composed of a gel electrolyte for a secondary battery and a porous film that is composed of at least one resin selected from the group consisting of polyethylenes, polypropylenes and polyimides. The gel electrolyte for a secondary battery is obtained by impregnating an electrolyte solution holding film with an nonaqueous electrolyte solution, and the electrolyte solution holding film contains a vinylidene fluoride copolymer resin that comprises a vinylidene fluoride unit and a tetrafluoroethylene unit at a vinylidene fluoride unit / tetrafluoroethylene unit molar ratio of from 55 / 45 to 95 / 5, while also containing a hexafluoropropylene unit in an amount of 0-10% by mole (with the total of the vinylidene fluoride unit, the tetrafluoroethylene unit and the hexafluoropropylene unit being 100% by mole).

The invention discloses an SBS (styrene-butadiene-styrene)-modified colorless cementing material which is prepared by mixing the following components in parts by weight: 43-70 parts of base oil, 28-50 parts of modifier, 2-7 parts of ethylene-vinyl acetate copolymer and 2-4 parts of styrene-butadiene-styrene block copolymer. The invention also discloses a preparation method of the SBS-modified colorless cementing material, which comprises the following steps: mixing the rubber oil, C5 petroleum resin, ethylene-vinyl acetate copolymer and styrene-butadiene-styrene block copolymer until the C5 petroleum resin, ethylene-vinyl acetate copolymer and styrene-butadiene-styrene block copolymer are sufficiently swollen and mixed in the rubber oil to form a uniform mixture, and adding methyl cellulose as a stabilizer, thereby obtaining the SBS-modified colorless cementing material. The SBS-modified colorless cementing material disclosed by the invention has the advantages of low cracking tendency at low temperature, excellent high-temperature stability, excellent water damage resistance, excellent viscoelasticity, accessible raw materials and lower cost.

The invention relates to a production method of simulation leather fiber raw materials, and provides a method for extracting dermal fibers by means of waste finished leather. According to the method, the waste leather is recycled and utilized, the utilization rate of resources is increased, a production technology is improved, on the condition that the quality of a finished product reaches the application standard, water consumption and electricity consumption can be greatly reduced, energy conservation is promoted, and the emission reduction effect is prominent. The method for extracting the dermal fibers by means of the waste finished leather comprises the following steps that 1, leftover materials are crushed into particle powder through a leather crusher, wherein the particle diameter ranges from 2 mm to 4 mm; 2, the particle powder is put into a drum for dyeing treatment; 3, the particle powder subjected to dyeing treatment is subjected to dehydration through a pass-type drying press ; 4, the particle powder subjected to dehydration is subjected to dehairing treatment through a dehairer, and fiber cotton is formed.

The invention discloses a composite fabric, characterized in that the composite fabric is composed of the following materials in parts by mass: 15-20 parts by mass of silk, 40-45 parts by mass of bamboo fibers, 35-45 parts by mass of cotton fibers and 45-50 parts by mass of big-belly yarns. The composite fabric is excellent in air permeability, low in cost, and high in comfort degree, and is fit for large-scale popularization and application.

The invention discloses blended yarn with health care and flame retardant functions and a spinning method thereof. The blending ratio of bamdal to chinlon to flame-retardant acrylic fibers is 10-60 / 10-60 / 30; the linear density of the blended yarn is 15-30 tex; the breaking strength of the blended yarn is 150-450 CN, and the elongation at break is 6-20%; the evenness of the blended yarn is 10-50%;the hairiness index of the blended yarn is 3-10%, the blended yarn does not shrink and melt when approaching flame for combustion, is subjected to shrinkage combustion or slow combustion in the flameand extinguished after leaving the flame. The blended yarn is formed by blending the three components including the bamdal, the chinlon and the flame-retardant acrylic fibers, the advantages of different fibers can be fully utilized and can be complementary, the spinnability of the fibers and the wearability of fabric can be improved, and the blended yarn can be applied to various industries of clothing for children, medical care, clothing with special operation requirements, home decoration and the like.

The invention belongs to the technical field of dyes, in particular to a composite reactive black dye, comprising a dye shown in formula (1), a dye shown in formula (2) and a dye shown in formula (3), in parts by weight The proportioning ratio is as follows: 50-100 parts of the dye of the formula (1), 5-45 parts of the dye of the formula (2), and 0-5 parts of the dye of the formula (3). The present invention also provides a black dye composition, including a color-fixing alkali agent, a dyeing accelerator and the above-mentioned composite reactive black dye. The composite reactive black dye provided by the present invention has higher dyeing depth, good color fixation rate and washing performance, and low raw material cost. The compounding of the three dyes of formula (3) makes the dyed fabric have higher level dyeing property, high color fixing rate and high fastness, and achieves unprecedented jet-black fullness and dyeing depth, and increases the washability of the dye It solves the problems of poor washability and serious color sticking of existing reactive black dyes, and is suitable for exhaust dyeing, pad dyeing and resist printing of fiber materials.

The invention relates to a method for dyeing Eimeria tenella protoplasts, comprising the following steps: (1) taking freshly separated immature Eimeria tenella oocysts, freezing and thawing cycles; (2) using hydrochloric acid-ethanol The oocysts after freeze-thaw cycles are treated, and after the action, centrifugal washing is performed to remove the action solution; (3) dye is added to perform fluorescent staining of Eimeria tenella protoplasts. The invention establishes a wall-breaking technology that preserves the complete shape of the oocyst wall of immature Eimeria tenella, and reports the staining method of the protoplast of Eimeria tenella for the first time. The procedure is simple, the method is credible, and the results are distinct. Easy to observe and judge.
