This invention discloses a hot melt adhesive for high-temperature protective clothing and its preparation method, comprising the following raw materials: Fischer-Tropsch wax, styrene-isoprene-styrene block copolymer with 0% diblock content, styrene-isoprene-styrene block copolymer with 20-30% diblock content, styrene-isoprene-styrene block copolymer with 40-50% diblock content, rosin resin, petroleum resin, ethylene-vinyl acetate copolymer, and antioxidant. This hot melt adhesive requires no toxic solvents, possesses both heat resistance and water resistance, and is suitable for high-temperature protective clothing. The preparation method of this hot melt adhesive involves heating and mixing polymer materials without adding any solvents or toxic substances during the preparation process, reducing the risk of toluene poisoning, completely solving the problems of solvent evaporation and recovery, and, more importantly, eliminating safety hazards in the storage and use of organic chemicals, achieving environmentally friendly, safe, and efficient production.

The utility model relates to the technical field of energy storage equipment, in particular to a battery and a battery module, the battery comprises a shell, the shell is provided with a first side wall and a second side wall which are oppositely arranged along a first direction, the first side wall is provided with a first clamping part, and the second side wall is provided with a second clamping part; the first clamping part of one of the adjacent batteries is clamped and matched with the second clamping part of the other battery, one of the first clamping part and the second clamping part which are clamped and matched is a clamping bulge, and the other one of the first clamping part and the second clamping part is a clamping groove. The battery module comprises a plurality of batteries, and the plurality of batteries are sequentially arranged along a first direction. The adjacent batteries of the battery module are not easy to shake relatively, so that the bonding failure of the insulating films is avoided, the insulating property of the batteries is ensured, the heat dissipation of the batteries is not influenced, and the cost is not excessively increased.

The invention discloses a method for inhibiting rust of rusted steel bars in a concrete structure, and aims to solve the problems that in the prior art, a safe, environment-friendly and long-acting steel bar corrosion inhibitor convenient to construct is lacked, and a long-acting steel bar corrosion prevention method formed by compounding materials such as an efficient anti-corrosion coating is lacked. Through three innovations of organic silicon modification, a nano-composite technology and a self-crosslinking system, the core problems of poor weather resistance, high VOC (Volatile Organic Compounds), insufficient dispersion stability and the like of the traditional acrylic emulsion are solved, and the acrylic emulsion is particularly suitable for severe environments with high ultraviolet rays, high humidity and the like, so that long-period corrosion prevention is realized, and the service performance of concrete is improved.

The utility model discloses a kind of polystyrene composite insulation board outer wall external thermal insulation structures, it is related to polystyrene composite insulation board technical field.It includes setting in order leveler, adhesive layer, thermal insulation layer, plastering mortar and glass fiber mesh layer, decorative layer;Thermal insulation layer is polystyrene composite insulation board material quality;Multiple preset slots are opened on thermal insulation layer;It further includes expansion bolt, and the bolt head portion fixed connection of expansion bolt is limited to limit plate, limit plate and preset slot correspond;Fixed groove is provided in limit plate outside;It further includes flexible gasket corresponding with preset slot.The utility model has the beneficial effects that this structure, it is more firm to be fixed on overall outer wall, when more not easy to crack or fall off when being impacted by external force.

The utility model provides an automatic chip mounting device for a battery array. The automatic chip mounting device comprises a pick-and-place mechanism, a dispensing mechanism, a platform mechanism and a movement mechanism. According to the utility model, the visual assembly is combined with the multi-axis module to realize high-precision placement and attachment of the cells, so that the alignment error of the cells and the cellular board is extremely small, and the photoelectric conversion efficiency is improved. And meanwhile, the double-screw dispensing mechanism is adopted, so that bonding failure caused by glue overflowing or insufficient glue amount is avoided. In addition, the suction cup assembly can grab a plurality of batteries at a time, and the production efficiency is improved.
