The application relates to the technical field of toughened glass, and discloses a multilayer composite laminated toughened glass, which comprises inner layer glass and outer layer glass, the two sides of the inner layer glass are provided with the outer layer glass, through holes are formed in the surface edges of the inner layer glass and the outer layer glass, connecting seats are arranged at the through holes of the inner layer glass, bolt columns are welded on the two sides of the connecting seats, and the bolt columns are penetrated into the through holes of the outer layer glass. In the application, the functional module layer is arranged between the outer layer glass and the inner layer glass, the connecting seat, the bolt column and the double-nut structure at the through hole of the inner layer glass are matched, the functional module layer can be quickly disassembled or replaced, the outer layer glass and the inner layer glass can be separated by only rotating the double nuts, the overall structure of the glass does not need to be damaged, the difficulty and the time cost of replacement are greatly reduced, the glass always maintains the best functional state, and remarkable economic and environmental protection benefits are achieved.

The invention relates to the field of polyester fabrics, and particularly discloses a preparation process of a waterproof flame-retardant polyester fabric. The preparation process of the waterproof flame-retardant polyester fabric comprises the steps that the polyester fabric is cleaned and dried, a waterproof agent, a flame retardant and a cross-linking agent are mixed to obtain finishing liquid, and the mass ratio of the waterproof agent to the flame retardant to the cross-linking agent is (10-20): (5-15): (1-5); dipping the dried polyester fabric in the prepared finishing liquid, and standing at room temperature for 12-16 hours; and carrying out vacuum drying on the impregnated fabric at 40-50 DEG C, and carrying out high-temperature setting at 150-180 DEG C after drying to obtain the waterproof flame-retardant polyester fabric. According to the preparation process of the waterproof flame-retardant polyester fabric, the problem that a traditional polyester fabric is insufficient in waterproof and flame-retardant performance is solved.

According to the metal wiredrawing line appearance process, stress is relieved through a plastic part, internal stress is reduced, and an electroplated product is prevented from deforming; the microcosmic roughness of the surface of the plastic part is increased through coarsening, and the contact area of an electroplated surface and the part is increased; the colloid palladium is exposed and has catalytic activity by removing the activating solution on the surface; the deposition speed is accelerated; a plating layer with good conductivity is formed through chemical plating, and it is guaranteed that a circuit can form a loop, so that the plastic part has conductivity; metal wire drawing lines are formed on the surface of plastic through composite electroplating of three metals of copper, nickel and chromium; compared with a traditional silver paint spraying and IML technology, the metal wire drawing line appearance technology has higher durability and better appearance effect; finer and more uniform metal wiredrawing textures can be realized through fine pretreatment and accurate electroplating control; the process provided by the invention not only improves the quality and performance of the product, but also reduces the production cost and shortens the production cycle.
