Embodiment 1
[0084] Combining Example 1 and Example 2, it can be seen that the thermal conductivity filler is added in two layers, and thermal conductivity fillers with different particle sizes are selected, the higher the thermal conductivity of the PET plus 25% glass fiber mold is. This is beneficial to heat transfer, making the temperature of the mold closer to the foaming temperature as much as possible. After the above improvements, the PET plus 25% glass fiber mold containing thermally conductive fillers can also reach a high temperature of 95-98 degrees, which is of great help to the welding and fusion quality of foam rubber materials.

Abstract
The invention discloses a novel foaming glue molding process, comprising the following steps: S1, preparing a radio frequency foaming mold, S2, installing the mold, and closing the mold; S3, preparing materials, preparing a foamed collagen material and mixing a polar medium material, and fully Stir to obtain mixture A; S4, tightly fasten the metal cover in the mold equipment to ensure that radio frequency waves cannot leak out; S5, filler, use vacuum and / or negative pressure to make mixture A enter the product cavity; S6, adjust the machine, adjust the radio frequency emission parameters of the radio frequency generator; S7, radio frequency heating, rapidly heat and heat up the mixture A through the radio frequency generator and weld and fuse it; S8, cool, absorb the mold by vacuum and / or negative pressure Heat, open the machine cover to carry out air cooling; S9, open the mold, take out the product. The new styrofoam molding process can improve the yield rate of processed products, reduce heat loss, and be more energy-saving and environmentally friendly; in addition, the heating and adjustment response speed is fast, ensuring the molding effect of the material.
Description
technical field [0001] The invention relates to the technical field of styrofoam molding, in particular to a novel styrofoam molding process. Background technique [0002] Styrofoam products have the characteristics of light weight, good quality, high strength, good cushioning and shock resistance, heat insulation, etc., and are widely used in human body protective gear, automotive energy-absorbing parts, heat preservation, packaging and other industries. Commonly used styrofoam materials include expanded polystyrene, expanded polypropylene, and expanded polyethylene. [0003] The styrofoam molding technology currently used in the industry mainly uses water vapor as a heat source, and industrial boilers are used to generate water vapor. However, the molding quality of this method is not easy to observe, and there are potential safety hazards, and the boilers used require large workshops. Occupying an area, it needs to use natural gas and coal combustion to generate heat at ...
