A seat belt device for stabilizing and positioning a flexible vehicle seat belt buckle having a substantially rigid support structure configured for combining with a vehicle seat belt buckle to convert a movable, flexible vehicle seat belt buckle to a substantially stationary seat belt buckle for facilitating engagement of a seat belt latch. The support structure includes splinting configurations and wedging configurations.

The invention discloses a toughened polyphenyl ether and nylon alloy and a preparation method for the toughened polyphenyl ether and nylon alloy. The toughened polyphenyl ether and nylon alloy comprises the following components in weight percentage: 20-60 percent of polyphenyl ether, 20-60 percent of polyamide, 5-20 percent of compatilizer, 5-20 percent of toughening agent and 1-2 percent of other additives. The incompatibility of the polyphenyl ether and nylon comprised by the invention is improved through the added compatilizer. Through changing the content of the toughening agent in the alloy material, the alloy material with different impact strength is obtained. A product prepared from the toughened polyphenyl ether and nylon alloy is capable of resisting the high temperature of at least 160 DEG C of a production line and the corrosion of dimethylbenzene and methylbenzene as solvents in spray paint; the contour dimension is kept unchanged; and the phenomena, such as stress cracking and the like, do not occur.

The invention belongs to the field of high polymer materials and relates to alumite chromatographic dye containing a hyperbranched polymer. The alumite chromatographic dye consists of the following components in parts by mass: 20-40 parts of acrylic resin, 20-40 parts of polyurethane resin, 1-5 parts of other resins, 7-20 parts of dye toner, 1-10 parts of hyperbranched polymer, 0.5-1.0 part of auxiliaries and 60-80 parts of solvent. The invention also discloses a preparation method of the alumite chromatographic dye containing the hyperbranched polymer. The preparation method comprises the following steps: putting an appropriate amount of solvent to a reaction kettle, and keeping the temperature in the kettle to 25-60 DEG C; putting the dye toner, the hyperbranched polymer and the auxiliaries to the kettle at one step and stirring for 1-4 hours; adding the acrylic resin, the polyurethane resin and other resins in sequence, controlling the temperature to 15-70 DEG C and stirring for 2-6 hours; finally enabling the materials to flow into a storage tank through a kettle body device for later use, wherein the internal temperature of the storage tank is 10-40 DEG C. The hyperbranched polymer has a three-dimensional spherical space structure, contains a large amount of polar and non-polar functional groups in chain segments and at the chain ends, has excellent dissolving property and low viscosity and has the capability of improving the problem that resin and dye toner are insoluble to each other in alumite chromatographic dye.
