Embodiment Construction

[0017] The following describes the implementation of the present invention in detail with reference to the accompanying drawings. The accompanying drawings are for reference and explanation purposes only, and do not constitute a limitation on the scope of protection of the patent of the present invention.

[0018] This embodiment provides a method for preparing a neoprene sponge. Neoprene is used as a foaming substrate, and after adding fillers, plasticizers, antioxidants, vulcanization systems, and foaming systems, the neoprene is made into neoprene. Rubber sponge, such as figure 1 As shown, the neoprene sponge 1 includes an upper skin layer 11, a middle layer 12, and a lower skin layer 13. The density of the upper skin layer 11 and the lower skin layer 13 is greater than the density of the middle layer 12, including:

[0019] Separating at least one intermediate layer from the intermediate layer of the neoprene sponge by a cutting step;

[0020] A fine embossing and pressing step i...

Abstract

The invention provides a preparation method of neoprene sponge. The neoprene sponge is prepared by taking neoprene as a foaming base material and adding components such as a filler, a plasticizer, an antiager, a vulcanization system and a foaming system. The neoprene sponge comprises an upper skin layer, an intermediate layer and a lower skin layer, wherein the densities of the upper skin layer and the lower skin layer are greater than the density of the intermediate layer; at least one intermediate sublayer is separated from the intermediate layer of the neoprene sponge by cutting; and the upper surface and the lower surface of the intermediate sublayer of the neoprene sponge are subjected to fine amboss pressing to form an upper fine amboss surface and a lower fine amboss surface. The method has the benefits that since the intermediate layer of the neoprene sponge is subjected to a fine amboss pressing technology and a coating technology, the utilization ratio of neoprene is increased, the production efficiency of the neoprene sponge is improved, the loss ratio can be reduced, and therefore, the production cost is lowered.

Description

Technical field [0001] The invention relates to the preparation field of chloroprene rubber sponges, in particular to a preparation method of chloroprene rubber sponges for improving the utilization rate of chloroprene rubber. Background technique [0002] The neoprene sponge prepared by foaming includes an upper skin layer, a middle layer and a lower skin layer. Because the density of the upper and lower skin layers is greater than that of the middle layer, the waterproof effect is good. Therefore, in the process of producing diving products, it is generally made from neoprene. The rubber sponge is cut including the upper and lower skin layers, and the upper and lower skin layers are colored and applied to diving products. [0003] In this way, the middle layer of the neoprene sponge is not used or needs to be applied through other processes, thereby greatly reducing the utilization rate of the neoprene rubber and increasing the production cost. [0004] Moreover, if the neoprene s...
