Manufacturing Method of Eco-Friendly Elastic Chip Using Waste Elastic Material {.}

1 is a manufacturing process diagram of an embodiment of the present invention

The present invention relates to a method for manufacturing an environmentally friendly elastic chip using waste elastic materials.

The present invention pulverizes a large amount of waste elastic materials, for example, waste rubbers such as waste tires, waste urethanes, waste pvc, waste vinyl, resin fragments generated in the synthetic resin injection process, and the like, and elastic coating films such as urethane resins. It is made of an elastic chip that can form a coating film from ash and purify and improve the water quality by tourmaline, so that it can be easily drained and used as a permeable flooring material for various uses including sports facilities.

In recent years, urban development and landscaping work require permeable pavement for the purpose of natural inflow of rainwater. Products such as elastic pavement and permeable concrete, which have various permeability, have been developed. In addition, attempts have been made to improve the bleak urban environment in which roads have been paved by general asphalt or concrete.

Such permeable road pavement has been attempted to develop a pavement having a function of maintaining strength to prevent cracking and settlement, and a water-permeable effect elasticity. To improve and purify the water quality of rainwater, to conserve groundwater resources and provide beneficial effects to the human body, and to develop methods that can be used more efficiently in terms of eco-friendliness and resource saving by using chips crushed waste rubber. have.

According to the present invention, a waste material such as a waste tire rubber chip is pulverized to a small size to form an elastic coating layer made of an elastic coating material, thereby exhibiting a state similar to that of a general urethane chip. In addition, tourmaline improves the quality of rainwater so that it can have a good effect on underground water resources and underground ecosystems.

Tourmaline is a rod silicate with hexagonal columnar crystals. It is a natural mineral belonging to hexagonal system, and crystal itself generates electricity. The hydrogen ions (H ⁺ ) are combined with the discharged battery by being attracted to the negative electrode and neutralized, and the hydrogen ions (H ₂ ) are evaporated to alkalinize the water. In addition, hydroxyl ions (OH ⁻ ) are bonded to the surrounding water molecules to form a surface active substance called a hydroxyl (H ₃ O ₂ ) anion.

The hydroxyl ions weakly water to the optimum pH7.4, and the far-infrared rays generated have a surprisingly high value, and have a strong thermal effect and high penetration to promote blood circulation, blood purification and thrombolysis effect on the human body. While stimulating autonomic nerves while always maintaining immune function in the human body to suppress the excitability of the sympathetic nerve and serves to reduce the acidified human body.

Therefore, when the flooring material having a function of emitting far infrared rays can be constructed by using crushed products of various kinds of rubber-based wastes, it will be possible to provide a road of environmentally friendly and beneficial environment by tourmaline while being pitched.

The present invention for achieving the above object is to apply a primer on the surface of the waste elastic material by stirring the 80 ~ 90% by weight of the waste elastic material and 10 to 20% by weight of the pulverized sorting and dried; 55-70% by weight of the waste elastic material coated with a primer and 30-45% by weight of the elastic coating material are agitated to form a primary elastic coating film on the surface of the waste elastic material, and sprayed with calcium carbonate to separate the granulated waste elastic material from each other. Primary curing; The secondary elastic coating film is formed by stirring 60 to 75% by weight of the primary cured waste elastic material and 25 to 40% by weight of the elastic coating material, and calcium carbonate 80 to 100% by weight of the waste tire elastic material on which the secondary elastic coating film is formed. 95% by weight and 5 to 20% by weight of tourmaline powder are sprinkled with the waste elastic material of the granular state, so as not to stick to each other by the secondary curing.
The waste elastic material may be selected from waste rubber, waste urethane, waste pvc, waste vinyl.
The elastic coating material may be selected from urethane resin, rubber resin, pvc resin, epoxy resin, vinyl resin, plastic resin.
