KR950000173B1 - Manufacturing method of rubber mat by waste tire - Google Patents

Abstract

The waste tire and the waste pieces of rubber product are washed and crushed to below 1.5 mm and 1.5-3.5 mm. The 1.5-3.5 mm crushed rubber 35-60 % and the crushed rubber below 1.5 mm are mixed and painted with acrylic paint ink in a ratio of rubber 90-95 % to ink 10-5 %, and then the colored rubber is adhered each other by binding them with multisulfur rubber adhesives in a ratio of rubber 85-95 % to adhesives 15-5 % and cured by hot wind to form rubber mat for interior ornaments. The rubber mat has a superior cushion property and acoustic effectiveness.

Description

Manufacturing method of rubber mat for interior decoration using pet tire

1 is a perspective view of the finished product of the present invention.

The present invention relates to a manufacturing method of a rubber mat for upholstery, more specifically, to finely pulverize waste tires or the rest of the rubber product and finely color them in the required color by adding ink paint, injecting adhesives and hot air. The present invention relates to a manufacturing method of a rubber mat for upholstery to enjoy cushioning and sound absorption through vulcanization and molding.

In general, artificial turf, pallet and mat products have been concentrated on synthetic resin materials that are easy to produce injection molding and have low product cost.However, as synthetic resin products, these products are inferior in cushioning function and sound absorption effect and are easily damaged. Had curable properties. In order to solve this problem, the necessity of development of the rubber mat has been raised, but the production cost, utilization of the finished product and disadvantages of the rubber were expected rather than the difficulty of the manufacturing method.

In order to solve such a conventional problem, the present invention was conceived to produce a mat for interior decoration by using the rubber of a tire having various physical properties. To understand the present invention, rubber properties of waste tires as raw materials of the present invention are understood. You need to understand first.

Automotive tires have various properties due to the quality requirements for safety, high-speed driving, durability, etc., so they have a high hardness and strong physical properties even when broken. In particular, the tread, which is a tire jacket, must have strong physical properties and must maintain strong adhesion, because without a strong tread, the tire's edge cannot withstand the disassembly and destructive force of the running vehicle.

In addition, tire treads, such as tires for trucks and buses, wear out and then regenerate the treads, making it difficult to regenerate unless the tires maintain strong adhesion to the used tires.

By crushing waste tires having such strong physical properties as they are, mixing and mixing adhesives and inks, and manufacturing rubber mats by hot air vulcanization and finishing operations, rubber mats of strong physical properties can be produced in a relatively simple process.

In addition, it is another feature that the incineration of waste tires can be produced at a lower cost at the time of becoming a social problem.

In particular, the use of polysulfide rubber adhesive as an adhesive in this method promotes bonding strength as the adhesive is vulcanized at 75-140 ° C. In particular, the adhesive material is good because it is the same material and the adhesive is the same as the properties of waste tires such as elasticity and tensile strength. To improve.

The rubber mat prepared as described above has a beautiful appearance and a three-dimensional appearance in comparison with the conventional homogeneous plate-like body, so that it has excellent elasticity and sound absorption effect in physical properties.

Furthermore, the rubber sheet is not made of a homogeneous material by heat treatment or blending of the mat product according to the prior art, but an acrylic color paint is applied to the surface of the small particles of the waste tire, and a polysulfide rubber adhesive is coated on the surface. It can be called a combination of particles.

As a result, the outer surface of the rubber plate has aesthetics as if it is a small number of particles. Technically, the waste tire particles and particles are solidified by the polysulfurized rubber adhesive to increase the strength together with the inherent adhesion, thereby firmly bonding the particles.

Therefore, the present invention will be described in detail by process as a method of manufacturing a rubber mat for interior decoration using waste tires.

[Step 1]

Waste tires used in the present invention and the rest in the production of rubber products are collected, washed and screened so that foreign substances cannot be included.

Second Process

The washed and sorted materials are put into a grinder and cut into the first stage, and the first mill is cut to a particle size of 7-10 mm or less, and the second mill is cut into second mills and then second milled to a particle size of 3,5 mm or less.

[Third process]

The pulverized particles are placed in a particle sorter and divided into 1.5 mm-3.5 mm and 1.5 mm or less.

[4th process]

35-60 to 1.5 mm-3.5 mm and 1.5 mm or less of the third process in the mixer; It is charged at 60-35%, and the color of the ink, which is a color acrylic paint having a viscosity of K.S 70-90, is colored by rotating the mixer with an input ratio of the total material and ink of 90-95: 10-5%.

[5th process]

The adhesive is adsorbed by rotating the mixer with a mixture of strength polyurethane 10 ± 2% and viscosity of 1000-1500K on the colored finished material, and the input ratio of the whole colored material and the polysulfide rubber adhesive is 85-95: 15-5%. .

[Sixth Step]

The material is made into a hot air vulcanizer at a temperature of 75-140 ° C. and a time of 5-10 minutes to form a shape that is easy to form.

[7th process]

Finishing of the vulcanized material into various surface forms (illustrated in FIG. 1) results in a rubber mat having a hardness of about 50-60.

As described above, the mat manufactured according to the method of the present invention uses the tire material as it is while using waste tires corresponding to industrial wastes, and thus has very strong, tough and adhesive properties. Of course, due to this, the impact resistance and sound absorption effect remain intact, so that it can be easily used for indoor floors or walls in a building, and it becomes a product that can be conveniently used for a bathroom or a veranda.
