Embodiment 2

[0051] like Figure 1-6 , Figure 9 As shown, the present embodiment provides the production process of the material storage tray of the LCD liquid crystal display, comprising the following steps:

[0052] S1. Preparation of storage tray body material: Dissolve polyurethane shape memory resin in N,N-dimethylformamide to obtain a sol, add elastomer and dicyandiamide to the sol at 25-35°C, and stir until it becomes a gel state, extruded by a twin-screw extruder, and supercritically dried to obtain the main material of the storage tray;

[0053] Among them, polyurethane shape memory resin is to add isocyanate, polyol and chain extender into the reactor, and carry out stirring polymerization at 40-50 ° C to obtain a linear polymer containing partial crystallization. The polymer uses its partial crystallization phase as the stationary phase. The polyurethane soft segment that undergoes reversible change between the glass state and the rubber state at the glass transition temperat...

Embodiment 3

[0062] This embodiment provides the production process of the material storage tray of the LCD liquid crystal display screen, and the difference from Embodiment 1 is that the elastomer in step S1 is selected from polyolefin thermoplastic elastomers; the addition amount of N,N-dimethylformamide is 16 times the mass of polyurethane shape memory resin; the mass ratio of polyurethane shape memory resin, elastomer, and dicyandiamide is 14:8:4; the extrusion temperature of twin-screw extruder is 206°C; the drying medium used in supercritical drying It is absolute ethanol, the drying pressure is 22MPa, the drying temperature is 46°C, and the drying time is 10 hours.

Abstract

The invention discloses a material storage disc of an LCD and a production process of the material storage disc, and relates to the technical field of display screen storage equipment. The material storage disc comprises a material storage disc body, the material storage disc body comprises a material storage area in the center and a stacking area arranged on the outer edge of the material storage area, adjustable fastening mechanisms are arranged at the positions, located on vibration buffering pads, in liquid crystal display screen containing cavities, and air bag vibration reduction mechanisms used for relieving shaking of the LCD are arranged in the material storage area. According to the material storage disc, stable clamping and fixing of the LCD are achieved, meanwhile, shaking and vibration generated in the taking, placing and carrying processes are relieved, and the stability of the LCD in the material storage process is improved. The production process comprises the steps of material preparation of the material storage disc body, injection molding, cooling demolding, installation of the adjustable fastening mechanisms, installation of the air bag vibration reduction mechanisms and installation of handheld parts, harsh conditions are not needed, the strength, elasticity, ventilation and heat dissipation performance of the material storage disc are guaranteed, and the material storage disc is suitable for large-scale production.

Description

technical field [0001] The invention relates to the technical field of storage equipment for display screens, in particular to a storage tray for LCD liquid crystal display screens and a production process thereof. Background technique [0002] Liquid crystal display, referred to as LCD in English, and its full name is Liquid Crystal Display, is a kind of flat-panel display used for the screen display of TVs and computers. The advantages of this display are low power consumption, small size, and low radiation. Liquid crystal displays are fragile electronic products, and most of them are packaged and transported through liquid crystal display trays or storage trays. [0003] The patent application number 201920035391.9 discloses a liquid crystal display tray, which includes a bottom tray body, a middle tray body and a top tray body. There are air bag clips, the liquid crystal display body is sandwiched between the four air bag clips, and the top of the air bag clip is provid...
