[0027] like Figure 1 As shown, the present disclosure provides a method for processing a foamed board, which at least includes a mixed material preparation step, a board extrusion step and a foaming step. The mixed material preparation step is to evenly mix various components in a mixed raw material containing a coffee grounds raw material to obtain a mixed material, and the mixed raw material at least includes a rubber raw material and a coffee grounds raw material; the board extrusion step is to place the obtained mixed material in an extruder, and extrude the mixed material by using the extruder to obtain an extruded board; the foaming step is to place the obtained extruded board in a foaming device for foaming to obtain a foamed board.

[0028] That is, in the processing method of the foamed board disclosed in the present invention, it is first necessary to extract the coffee grounds raw material into the coffee grounds raw material, and then the various components in the mixed raw material containing the coffee grounds raw material are evenly mixed to obtain a mixture, and the obtained mixture is placed in an extruder, and the mixture is extruded by the extruder to obtain an extruded board, and finally the obtained extruded board is placed in a foaming device for foaming to obtain a foamed board.

[0029] The foamed board obtained by the processing method of the foamed board disclosed in the present invention can recycle the coffee grounds left after making coffee, which is more environmentally friendly; it can effectively reduce the rubber smell in the foamed board and effectively increase the coffee aroma, effectively improving the user experience when using the foamed board disclosed in the present invention.

[0030] It can be understood that the above steps are only part of the processing method of the foamed board. After obtaining the foamed board, the foamed board needs to be subjected to preliminary cutting, internal mixing, open mixing, composite vulcanization, heat dissipation and fine cutting using a punch press to finally obtain the finished board. The finished board may include yoga mats, thermal insulation boards, sound insulation boards and other products, which are not limited here.

[0031] In one embodiment of the present disclosure, the coffee grounds raw material is coffee grounds powder. It is understandable that, when the coffee grounds raw material is coffee grounds powder, in order to ensure that the coffee grounds powder is exposed in the obtained foamed board, the coffee grounds powder can be ground into fine powder.

[0032] In another embodiment of the present disclosure, the coffee grounds raw material is coffee grounds extract, that is, coffee grounds powder is extracted to obtain coffee grounds extract, and the coffee grounds extract is used as the coffee grounds raw material. In this way, the substances with coffee aroma in the coffee grounds powder can be extracted, and the residual waste in the coffee grounds powder can be removed at the same time, which can effectively reduce the impact of the residual waste in the coffee grounds powder on the performance of the foamed board.

[0033] In one embodiment of the present disclosure, before extracting the coffee grounds powder into coffee grounds extract, the coffee grounds powder can be pre-cooled to 25°C-30°C to protect the extractant, ensure the extraction effect, and improve the selectivity and efficiency of the extraction, thereby ensuring that the substances with coffee aroma in the coffee grounds powder can be effectively extracted.

[0034] In one embodiment of the present disclosure, the step of uniformly mixing various components in a mixed raw material containing coffee grounds raw material to obtain a mixed material includes: Various components in the mixed raw material containing coffee grounds are placed in an internal mixer, so that the various components in the mixed raw material are evenly mixed by the internal mixer to obtain a mixed material.

[0035] That is, the step of uniformly mixing various components in the mixed raw material containing coffee grounds raw material to obtain the mixed material can be carried out in an internal mixer. In this way, it can not only ensure that the various components in the mixed raw material containing coffee grounds raw material are uniformly mixed by the rotation and friction force in the internal mixer, but also be processed into a uniform mixed material.

[0036] Further, in one embodiment of the present disclosure, the steps of placing various components in a mixed raw material containing coffee grounds raw material in an internal mixer to uniformly mix the various components in the mixed raw material to obtain a mixed material include: The various components in the mixed raw material containing coffee grounds are placed in an internal mixer, so that the various components in the mixed raw material are evenly mixed by the internal mixer at a temperature of 100 to 140 degrees to obtain a mixed material.

[0037] In this way, in the process of mixing various components in the mixed raw material containing coffee grounds raw material using an internal mixer, the internal mixer can make the mixed raw material be at an ambient temperature of 100 to 140 degrees, so that the mixed raw material has good processability and fluidity at an appropriate temperature, thereby better promoting the uniform mixing of various components.

[0038] Specifically, in one embodiment of the present disclosure, the mixed raw material includes a solid rubber raw material and a coffee grounds raw material, wherein the weight of the solid rubber raw material is 60 to 80 parts, and the weight of the coffee grounds raw material is 2 to 5 parts. When the weight of the solid rubber raw material is 60 to 80 parts, and the weight of the coffee grounds raw material is 2 to 5 parts, it can ensure that the coffee aroma of the obtained foamed board is relatively suitable, and can effectively ensure that the structural strength of the obtained foamed board can meet the requirements.

[0039] In one embodiment of the present disclosure, the mixed raw material further includes coffee flavor environmentally friendly essence, and the weight proportion of the coffee flavor environmentally friendly essence is 1 to 5. By adding coffee flavor environmentally friendly essence to the mixed raw material, the aroma loss of coffee grounds caused by excessively high temperature in the subsequent foaming step can be effectively compensated, ensuring that the obtained foamed board can have the special aroma of coffee, and covering and reducing the odor of the solid rubber raw material itself.

[0040] In one embodiment of the present disclosure, the mixed raw materials of the present disclosure also include calcium powder, and the weight proportion of the calcium powder is 30 to 50 parts.

[0041] It can be understood that in one embodiment of the present disclosure, the mixed raw materials of the present disclosure may also include other processing aids, such as lubricants, activators, plasticizers, antioxidants, protective agents, plasticizers, cross-linking agents, UV inhibitors, etc. These processing aids can improve the performance and quality of the foamed board by changing the physical and chemical properties of the foamed board.

[0042] In one embodiment of the present disclosure, the step of placing the obtained extruded board in a foaming device for foaming includes: placing the obtained extruded board in a foaming oven for foaming, wherein the temperature in the foaming oven is 100 to 170 degrees. Since in the processing method of the foamed board of the present disclosure, the obtained extruded board is placed in a foaming oven for foaming, and the temperature in the foaming oven is 100 to 170 degrees, it can effectively ensure that the foaming reaction rate is within a suitable range, and a good foam structure can be formed in the foamed board, thereby improving the mechanical properties and durability of the obtained foamed board.

[0043] Furthermore, in one embodiment of the present disclosure, the step of placing the obtained extruded sheet in a foaming oven for foaming includes: placing the obtained extruded sheet in a foaming oven, and keeping the extruded sheet rotating in the foaming oven at a speed of 50 to 100 revolutions per minute.

[0044] By placing the extruded sheet in a foaming oven and keeping the rotation speed at 50 to 100 revolutions per minute, the density, uniformity and overall quality of the obtained foamed sheet can be effectively guaranteed.

[0045] The present disclosure also provides a foamed board, which is made according to the processing method of the foamed board.
