Problems solved by technology

In the process of processing, the shrinkage of the material is very serious, which makes the joints of the product uneven in size and poor in appearance, especially when the porous product is laminated with leather or real microfiber, due to the large shrinkage of the material, each hole The gap between leather or real microfiber is uneven, the yield rate of the final product is low, and most of them cannot be reworked, resulting in waste of materials

Embodiment 1

[0036] Composite material anti-shrinkage processing method of the present invention, it comprises the steps:

[0037] Step S1: Take the first material layer of the entire roll, and cut the first material layer of the entire roll into blocks with an area of ​​less than one square meter, so as to facilitate the processing of the first material layer in the later stage. In this embodiment, the first material layer One material layer is leather.

[0038] Step S2: Preheat the cut first material layer at a temperature of 80°C-140°C for 0.5 minutes to 5 minutes; until the first material layer shrinks, the preheating is carried out by plane hot pressing or direct heating. The hot pressing is carried out by using a heat press machine, the hot pressing temperature is 100° C. to 140° C., and the hot pressing time is 1 to 5 minutes. The first material layer is put into the heat press machine for direct hot pressing. In this embodiment, the hot-pressing temperature is 120° C., and the hot...

Embodiment 2

[0048] The processing method of the electronic product protective case of the present invention, it comprises the following steps:

[0049] Step S1: Take the whole roll of leather material layer, and cut the whole roll of leather material layer into blocks less than one square meter. In this embodiment, it is cut into pieces of 120mm*200mm, so as to facilitate the planar hot-pressing treatment. The leather material layer is genuine cowhide, sheepskin or microfiber material.

[0050] Step S2: Preheat the leather material layer at a temperature of 80°C-140°C for 0.5 minutes to 5 minutes until the leather material layer shrinks; the preheating is carried out by plane hot pressing or direct heating, and the plane hot pressing is by heat press The heat press temperature is 100°C-140°C, and the heat press time is 1-5 minutes. Put the leather material layer into the heat press machine for direct heat press. In this embodiment, the hot-pressing temperature is 120° C., and the hot-pr...

Abstract

The invention discloses a shrink-proof processing method of a composite material and a processing method of a protective shell of an electronic product. The composite material anti-shrinkage processing method comprises the following steps: taking the first material layer, cutting the first material layer into pieces; preheating the first material layer at a temperature of 80°C-140°C for 0.5 minutes to 5 minutes Minutes; after plane hot pressing, the first material layer is naturally placed at room temperature for 12 hours to 48 hours; a second material layer is provided, hot melt adhesive is attached on the first material layer, and the first material layer has One side of the hot melt adhesive is located on the plane part of the second material layer, and is initially pressed; the first material layer and the second material layer that are pressed together are naturally placed at room temperature for 1 minute to 60 minutes; The first material layer and the second material layer are bonded again by thermocompression. The anti-shrinkage processing method of the composite material in the invention can greatly reduce the shrinkage of the material, has a smooth and uniform appearance, and has a high yield rate.

Description

technical field [0001] The invention relates to the technical field of electronic product protection, in particular to a composite material anti-shrinkage processing method and a processing method for electronic product protection shells. Background technique [0002] At present, in the field of composite material processing, especially leather or real microfiber materials, the commonly used processing technology is to cut first, trim and then hot-press and bond other materials together. In the process of processing, the shrinkage of the material is very serious, which makes the joints of the product uneven in size and poor in appearance, especially when the porous product is laminated with leather or real microfiber, due to the large shrinkage of the material, each hole The gap between leather or real microfiber is uneven, the yield rate of the final product is low, and most of them cannot be reworked, resulting in waste of materials. Contents of the invention [0003] B...
