A kind of plant fiber elastic material cutting vulcanization production method

Abstract

The invention discloses a production method for cutting and vulcanizing a plant fiber elastic material. Plant fiber elastic sheets are produced. The method is characterized by comprising the following steps: by taking the direction of discharging the elastic sheets along a production line as a longitudinal direction and a direction of the elastic sheets perpendicular to the production line as a transverse direction, stacking the longitudinal elastic sheets and the transverse elastic sheets, performing hot-pressing on the stacked elastic sheets, cutting the elastic material, trimming, vulcanizing, and packaging, thereby obtaining the elastic material. The plant fiber elastic material disclosed by the invention is small in deformation, the cutting amount is reduced, and the production raw materials are saved. Moreover, the defects on the elastic sheets can be overcome by virtue of cut leftover materials, and the quality of the elastic material is improved.

Description

technical field [0001] The invention relates to a production method for cutting and vulcanizing plant fiber elastic materials, belonging to the technical field of plant fiber elastic materials. Background technique [0002] Plant fiber elastic material is an elastic material made of natural plant fibers, including mountain palm, coconut shell, oil palm, hemp, bamboo, etc. It can be used to make mattresses, cushions, cushions, pillows, sound insulation materials, shock absorption materials, etc. Chinese patent 90100464.2 discloses a production method of plant fiber elastic material. After the plant fiber silk is crimped, it is blown into a three-dimensional distribution shape with an air flow and then sprayed with glue, so that the nodes between the brown silk are bonded to obtain a plant fiber elastic sheet, and then the The elastic sheets are stacked to obtain an elastic material. Chinese patent 200810302045.9 discloses a vulcanization method of plant fiber elastic materia...

AI Technical Summary

Problems solved by technology

Such a stacking method has been found by the applicant through research. The original lamination process of all plant fiber elastic materials is stacked along the direction of the production line, resulting in irregular and large dimensional changes of the elastic material during subsequent vulcanization. Therefore In order to ensure that the size of the processed elastic material is consistent, the reserved cutting side width of the stacked elastic sheet must be wider to ensure the processing quality. Usually the reserved cutting side width is about 8% of the elastic material side width

Moreover, the strength of elastic materials in different directions is different. The strength along the production line is high, while the strength perpendicular to the production line is low. The mechanical properties of elastic materials are inconsistent in all directions. The elastic materials will have a series of quality problems such as collapse and bulging during use.
