Abstract

The present invention recycles resources by crushing hundreds of thousands of tons of rubber such as waste tires and shoe soles, which are discharged annually, according to the purpose, and provides a more comfortable and comfortable walking feeling for people, while also saving resources and recycling more efficiently and efficiently. By using waste tire chips, urethane binders, other rubber chips and silica sand, it is possible to reduce costs and resources, improve comfort for users, prevent accidents, reduce groundwater exhaustion, and identify problems with existing elastic mats. The purpose is to improve and supplement.

The main mats used in children's playgrounds are mainly 500X500X25-50t, but the deformation of the product has been seriously caused by the flatness of the design due to the wide top and the bending of the bending due to the wide single face. In order to minimize these shortcomings and to minimize the dissatisfaction for consumers who are familiar with the existing size, the upper part of the existing 500X500X25-50t mat is divided into four quarters, and through the perforations, groundwater depletion and freezing in winter It is expected to help prevent accidents by preventing them.

Description

Water permeability of rubber mat which is used by recycle tire.}

The present invention intends to use hundreds of thousands of tons of waste tires and rubbers produced annually to be finely pulverized according to the purpose and to be used more efficiently and productively in terms of resource recycling and resource saving. Conventionally, as mentioned above, a large amount of waste tires have been consumed and then disposed of, or used as it is for military bases, roads, soundproof walls, etc., or left unattended, causing destruction of the natural environment and environmental pollution. . In order to solve these problems, the government recognizes the necessity of recycling the environment and resources, and is trying to change various benefits and government policies, and many companies keep pace with this to make rubber chips and other materials finely crushed waste tires and rubber. By mixing these products, various products such as road blocks and mats are provided.

As described above, the waste tires were mixed with various mixtures to manufacture, sell, and construct mats, but were accompanied by various problems in terms of functionality. First of all, the design was smooth, and secondly, the warping of the mat, and thirdly, rainwater and air could not penetrate, bringing water traps and destruction of the ecosystem, which would cause costly maintenance and inconvenience to the citizens.

The present invention was devised to solve the above problems. The waste rubber chips were crushed to a certain size at the upper and lower ends, and the lower layer part was mixed with silica sand, a tire rubber chip, a general rubber chip, and a urethane binder at a predetermined ratio. After mixing and mixing a certain amount of silver pigment, waste tire rubber chip and urethane binder, it is put in a press mold and molded for a certain time to complete the product. In addition, to prevent deformation due to temperature, silica sand, permeable voids and water flow paths are made, and the product which is divided into four quadrants in order to prevent deformation and warping due to temperature change in winter and summer is manufactured by 500x500x25 ～ 60T. And so on.

Permeable rubber mat of the present invention for achieving the above object,

5-10 parts by weight of pigment and 10-20 parts by weight of urethane binder are mixed with respect to 100 parts by weight of waste tire rubber chips, and the upper part layer formed with a water flow path and a permeable hole, and 100 parts by weight of waste tire rubber chips and general rubber chips. 10-20 parts by weight of the urethane binder, 5-20 parts by weight of silica sand is mixed, and consists of a bottom layer formed with a bottom permeable hole communicating with the perforation hole of the top layer.

In providing the lower end layer 7 composed of the waste tire and the general rubber chip 3 and the upper end layer 6 provided with the waste tire fine chip 2, the waste tire and the general rubber chip provided above ( 3) is used to select only the chip without cracks on the surface, there is no bending or warping phenomenon on one side, the upper layer 6 is a fine tire (2) of waste tire fine diameter of about 1-2mm diameter pigment (1) It is provided in combination with the colored layer provided, the lower layer (7) is a chip of about 3-8mm diameter of the chip is provided by mixing with the size of silica sand 3-7mm so that the chip (2) (3) evenly mixed. The urethane binder (5) having excellent adhesion is used, and an adhesive strong in weather resistance is used. The water flow path 11 of the upper layer is formed lower than the upper surface of the rubber mat in a cross shape at the center of the water-permeable rubber mat, and the water permeable hole 10 is formed on the water flow path 11.

Production of the water-permeable rubber mat,

Blending 5-20 parts by weight of silica sand and 10-20 parts by weight of a urethane binder with respect to 100 parts by weight of waste tire chips to prepare the bottom part layer 7, and injecting the bottom part layer into a press mold mold; 5-10 parts by weight of pigment and 10-20 parts by weight of a urethane binder were added to 100 parts by weight of the fine tire waste tire, and the upper layer was put on the upper surface of the lower layer put into the press mold to pressurize with a heat press. In a step to produce a permeable rubber mat.

Hereinafter, with reference to the accompanying drawings will be described in detail a water-permeable rubber mat using the waste tire chip of the present invention.

1 is a perspective view illustrating the present invention, FIG. 2 is a plan view of the present invention, FIG. 3 is a cross-sectional view of the present invention, and FIG. 4 is an enlarged cross-sectional view of the permeable gap of FIG. 3.

As shown in Fig. 1, the permeable rubber mat of the present invention is a 500x500x25-60T rectangular permeable rubber mat in which the upper end layer 6 is integrally attached to the lower end layer 7. The lower layer 7 is a layer of 3-8 mm particle size waste tire chips and general rubber chips 3 and silica sand having a particle diameter of 3-7 mm mixed with the urethane binder 5, and the upper layer layer 6 has 1- 2 mm of the waste tire chip 2 and the pigment 1 are mixed, and the upper layer has a water hole 11 and a water permeable hole 10 formed on the water flow path.
