Abstract

This invention relates to a method of continuously making anti-skidding foaming material with 3-dimensional patterns. This invention uses thermal plastic rubber particles to make a roll of foaming material sheet. A heat resistant cloth is adhered to a surface of the foaming material sheet. A heating device is then used for heating the foaming material sheet to soften the foaming material sheet to a plastic state. A calendar formed on a surface thereof with plural, small indents then rolls over the foaming material sheet in the plastic state, such that the portion that sustains a higher force would move towards the portion that sustain a lower force, and runs through the openings of the heat resistant cloth drawn by the heat resistant cloth, so as to form consistent and 3-dimensional patterns on the surface of the foaming material sheet. At this time, the foaming material sheet is cooled and rolled up to complete the process of continuously making anti-skidding foaming material with strong and 3-dimensional patterns.

The technical field to which the invention belongs ... The present invention relates to a method for manufacturing a foamed material. The foamed material sheet body i continuously manufactures a structure with a firm structure and a convex texture. A kind of three-dimensional previous technology that can be used in the whole roll: Generally speaking, it is often used in daily life. The rubber hair is weak and cannot be made into a sheet. In addition, the roll is flat, which solves this problem. After the material sheet body, the material sheet body surface material sheet body surface sequence, working hours and production and its own use of strong body after that, to solve these hair 'rubber foam is being processed in production, used to make material to bear Larger squares or long-distance collection and handling have not been able to highlight the problem, so the mold surface has a lot of friction, and the cost is still insufficient. Although some foamed material sheet materials have flooring, cushions to absorb vibration, and shear stress of the foamed material, in the course of the square sheet body, these positive effects are made due to the anti-slip effect of the foamed material sheet body. Hot pressing has a convex shape but this method cannot solve the problem. Therefore, there is a good son or its sound insulation and sheet body. These hairs are 'surfaces to avoid tearing'. Therefore, a square or shaped square pattern is The elasticity is greatly limited by the foaming. It cushions the slip, and the foam material itself breaks when rolled into rolls. Generally, it is made of rectangular type. When the material is increased, the netting and damping characteristics are generally increased. However, due to the strength of the material, Sheets of general foaming materials 0 are manufacturers, for the foaming materials, such foaming special foaming material production process body continuous volume foaming material sheet foaming material sheet processing and manufacturing, ^ unable to mass production and its own strength Inadequacy

Invention ^ 1 " '---- Under the influence of the cloth, the mesh of the high temperature resistant mesh is balanced, and the surface of the foam material sheet is uniformly and three-dimensionally convex. The foamed material sheet body is immediately subjected to cooling treatment, and the entire roll of the foamed material sheet body can be continuously made into a non-slip foam material with a solid structure and a three-dimensional convex pattern. χ, Another object of the present invention is to introduce frozen water into the roller in a circulating manner so that the surface of the roller forms a low-temperature state. 苴 = When the sheet is rolled to form the three-dimensional convex patterns, it can stand The f-foam material sheet body is used to shape these three-dimensional convex patterns to continuously produce a non-slip foam material with three-dimensional convex patterns. In order that the review committee can further understand the purpose, characteristics and methods of the present invention, the calculation of the Olympic Games ^. The detailed description is as follows: understand the examples of the Xuanjubei scheme and the details of the scheme to facilitate the characteristics The foam thickness of the foaming material is 10, and the sheet 20 plastic elastic elastomer particles are foamed in the heat-resistant plastic elastomer of the present invention to perform the edge removal and refer to Sections 1 and 2 for material 10 cutting edges. It is easy to predict in the process of replacing traditional one by one. After the hair is placed in the "mold and removed from the mold" to form a stack, the sheet body 20 can be formed according to the actual implementation method. The rubber raw material is heated and molded into the process tool. After using a kind of heat to use the kind of bomb, the first kind of operation is made, and the material is 10, and the foamed corresponding side body colloid is foamed. As shown in the self-trimming process diagram, multiple pieces are connected together to form one! 236414

The entire roll of continuous foamed material sheet body 2 1. A. In the process of the present invention, referring to Figures 1 and 2, a high-temperature-resistant mesh cloth 40 having a predetermined mesh size 41 can be adhered and fixed to the continuous roll of foamed material sheet 2 1 on one side surface (it can also be adhered and fixed on the two side surfaces according to actual needs) to form the semi-finished product 50 of the anti-slip foam material of the present invention. Thereafter, the high-temperature-resistant mesh cloth 4 is coated. The entire roll of continuous ^ foamed material sheet 21 is conveyed to a heating device. See FIG. 3, using the high temperature generated by the heating device 60, to heat the foamed material sheet 1 'Let's The foamed material 丨 Q is softened to the extent that it can be plasticized, and then it is rolled with at least one set of rollers 70 and 71.
