The invention discloses a pistol lamp rapid removal device which comprises a pistol lamp base, locking blocks correspondingly arranged on the two sides of the top end of the pistol lamp base, slidingdevices and a pressing mechanism; sliding chutes are correspondingly formed in the middles of the locking blocks; the sliding devices are mounted in the sliding chutes separately; a through groove penetrating through the pistol lamp base is correspondingly formed in the pistol lamp base; a gear plate is arranged in the middle of the through groove; and the pressing mechanism is mounted in the through groove and is matched with the gear plate. The pistol lamp rapid removal device rapidly detach the pistol lamp without an auxiliary lamp or great strength and is convenient to use.

The invention relates to starch-base degradable bioplastic and a preparing method thereof, and belongs to the technical field of biodegradable materials. The starch-base degradable bioplastic is prepared from 40-85% of commodity polymer plastic, 10-50% of a high-hydrophobicity starchiness material, 0.5-5% of aliphatic polyester and 0.1-5.5% of oxidation accelerator. The preparing method of the starch-base degradable bioplastic includes the following steps that starch is treated in a hydrophobization mode to obtain the high-hydrophobicity starchiness material, the raw material components are mixed by a ratio and prepared into master batch through a twin-screw extrusion machine, and after the master batch and the commodity polymer plastic are mixed, the starch-base degradable bioplastic is prepared through injection molding, flattening, blow molding, vacuumizing and forming. The product prepared through the method can be used repeatedly on the dry condition without perpendicular sunlight incidence, the strength is kept unchanged basically, an abandoned product is completely decomposed finally in wet soil, no harmful component is generated, and the environment is not polluted.

The invention provides a fruit-flavored soymilk added with a stabilizer. The fruit-flavored soymilk comprises, by mass: 35% of soymilk, 10% of pure fruit juice, 7% of sucrose, 0.1% of citric acid, and 0.05% of malic acid. The fruit-flavored soymilk is characterized by also containing the stabilizer, which is one of CMC (carboxyl methyl cellulose), xanthan gum, carrageenan and PGA (propylene glycol alginate). From the technical level, the problem that juice and soymilk cannot be mixed is completely broken, so that the nutritional ingredients of fruit juice and soymilk are fused in a beverage, and people can drink a cup of soymilk containing the nutritional ingredients of two food. Thus, the fruit-flavored soymilk added with a stabilizer involved in the invention can get the public's praise.

The invention belongs to the technical field of printing and dyeing auxiliaries, particularly relates to an ice feeling finishing agent and a preparation method thereof. The ice feeling finishing agent mainly comprises raw silicone oil, an emulgator, a cosolvent, glacial acetic acid and water, wherein the raw silicone oil is prepared by adding 99-99.5% of silicone oil, 0.01-0.9% of a silane coupling agent and 0.01-0.1% of a catalyst into a reaction kettle for reaction. According to the ice feeling finishing agent and the preparation method thereof, provided by the invention, primary amine or / and secondary amine is / are introduced onto the molecular chain of silicone oil, therefore the hydrophilic performance of the overall molecular structure is improved, fabric subjected to finishing of the finishing agent has air-permeating, moisture permeating, moisture-absorbing and sweat releasing functions, at the same time can maintain a certain humidity, and enables people to have a feeling of comfortableness and coldness after wearing the clothes subjected to finishing; besides, the ice feeling finishing agent has excellent stability, thoroughly overcomes the defects that the conventional amino silicon oil is prone to demulsification, floating and roll sticking, can easily produce oil spots, and is not easy to repair.
