preparation example Construction

[0018] A method for preparing a composite rubber floor for a gymnasium provided by an embodiment of the present invention comprises the following steps:

[0019] Step 1. Mix the isocyanate adhesive and acetone evenly, then add superfine rubber powder and mix evenly to get the glue, and set aside;

[0020] Step 2. Add acetone to the rubber particles to make the surface of the particles viscous, then add high wear-resistant carbon black, polyvinyl chloride, glass fiber, tourmaline powder, and hexacyclic stone powder, and mix evenly to obtain a mixed base material;

[0021] Step 3. Add the glue solution obtained in step 1 to the mixed base material obtained in step 2, and after mixing evenly, press the obtained mixture into a floor base material by means of hot pressing.

[0022] In the embodiment of the present invention, the prepared floor substrate is made of the following raw materials in weight percentage: 5-15% of superfine rubber powder, 15-30% of polyvinyl chloride, 1-5% ...

Embodiment 1

[0031] In this embodiment, raw materials for composite rubber flooring are prepared according to the following raw material weight ratio.

[0032] 10% of superfine rubber powder, 30% of polyvinyl chloride, 2% of tourmaline powder, 3% of hexacyclic stone powder, 5% of glass fiber, 5% of high wear-resistant carbon black, and 45% of rubber particles. The sum of the mass percentages of the above raw materials is 100%. The rubber particles used are nitrile rubber particles with a particle size of 30-100 mesh, and the rubber powder used is nitrile rubber powder with a particle size of 200-300 mesh. The particle size of the used tourmaline powder and hexacyclic powder is controlled at 50-200nm.

[0033] The preparation steps of a kind of gymnasium composite rubber floor are as follows:

[0034] Step 1. Mix the isocyanate adhesive and acetone evenly, then add superfine rubber powder and mix evenly to get the glue, and set aside;

[0035] Step 2. Add acetone to the rubber particles ...

Embodiment 2

[0041] In this embodiment, raw materials for composite rubber flooring are prepared according to the following raw material weight ratio.

[0042] 15% of superfine rubber powder, 20% of polyvinyl chloride, 5% of tourmaline powder, 5% of hexacyclic stone powder, 8% of glass fiber, 7% of high wear-resistant carbon black, 40% of rubber particles, the sum of the mass percentages of the above raw materials is 100%. The rubber particles used are nitrile rubber particles with a particle size of 30-100 mesh, and the rubber powder used is nitrile rubber powder with a particle size of 200-300 mesh.

Abstract

The invention discloses a preparation method of a composite rubber floor for a gymnasium. The method comprises the following steps: (1) mixing an isocyanate adhesive with acetone evenly and adding ultrafine rubber powder for mixing evenly to obtain a glue solution for later use; (2) adding acetone to rubber particles, making the surfaces of the particles sticky, then adding high abrasion furnace black, polyvinyl chloride, glass fiber, tourmaline powder and hexacyclic stone powder and mixing evenly to obtain a mixed base material; and (3) adding the glue solution obtained in the step (1) to the mixed base material obtained in the step (2), mixing evenly and pressing the obtained mixture into a floor base material in a hot pressing manner. According to the preparation method, the wear resistance of the composite rubber floor can be improved and the production cost can be reduced.

Description

technical field [0001] The invention belongs to the technical field of floor preparation for gymnasiums, and more specifically relates to a preparation method for composite rubber floors for gymnasiums. Background technique [0002] Rubber flooring is widely used in the ground laying of sports venues. Due to the high-speed movement or sudden jump of the human body, the floor needs to have a certain degree of elasticity to enhance the bouncing effect of the movement, so as to protect the athletes' limbs and reduce sports injuries. Existing composite rubber floors for sports venues are often prepared by compounding wood and rubber, which not only has poor wear resistance, but also has high production costs. Contents of the invention [0003] The object of the present invention is to provide a method for preparing a composite rubber floor for gymnasiums, which can improve the wear resistance of the composite rubber floor and reduce production costs. [0004] The present inve...
