Embodiment 1

[0016] Wheat straw is selected and processed into straw powder with a diameter of 0.5-5 mm after being dried and crushed.

[0017] Use waste tires and hose rubber products to make rubber powder with a diameter of 1-8mm through crushing, separation, and granulation processes.

[0018] Mix the above-mentioned straw powder, rubber powder and polyurethane adhesive according to the ratio: 20 parts of plant straw powder, 70 parts of waste rubber powder, and 10 parts of polyurethane adhesive; Under the condition of 10 minutes, after 10 minutes of solidification and molding, the straw waste rubber composite floor tiles were obtained. Floor tiles are 8mm thick.

Embodiment 2

[0020] Rice straw is selected and processed into straw powder with a diameter of 0.5-5 mm after being dried and crushed.

[0021] Use waste tires and hose rubber products to make rubber powder with a diameter of 1-8mm through crushing, separation, and granulation processes.

[0022] Mix the above-mentioned straw powder, rubber powder and polyurethane adhesive according to the ratio: 15 parts of plant straw powder, 80 parts of waste rubber powder, and 10 parts of polyurethane adhesive; Under the condition of 15 minutes, after 15 minutes of solidification and molding, the straw waste rubber composite floor tiles were obtained. The thickness of the floor tiles is 60mm.

[0023] The floor tiles of the above two embodiments have been tested: the tensile strength of the floor tiles is 1.3 MPa, the elongation at break is greater than 108%, the rebound value is greater than 20%, and the Shore A hardness is 55 degrees.

Abstract

The invention discloses a floor tile, and more particularly relates to a plant straw-waste rubber compound floor tile which is manufactured by utilizing plant straw and waste rubber. The compound floor tile is manufactured by taking plant straw powder and waste rubber powder as main raw materials and adding polyurethane adhesive to be evenly mixed and hot pressed. The raw materials comprises the following components according to parts by weight: 10-20 parts of plant straw powder, 70-85 parts of waste rubber powder, and 8-13 parts of polyurethane adhesive. The detection proves that the tensile strength of the floor tile reaches 1.3MPa, the tensile elongation thereof is more than 108 percent, the rebound value thereof is more than 20 percent, and the Shore A type hardness thereof is 53-58 degrees. The compound floor tile has the beneficial effect of changing wastes into valuables, compounding straw with waste rubber, and reducing the cost of the waste rubber compound floor tile.

Description

technical field [0001] The invention relates to a floor tile, in particular to a composite floor tile made of plant straw and waste rubber. Background technique [0002] Various plant straws, such as plant straws such as wheat and rice, and waste rubber products such as discarded tires and rubber hoses have not been fully utilized at present. Especially the processing of waste rubber glue has also caused serious pollution to the environment. At present, some use pure waste rubber to make floor tiles. The floor tiles made have good elasticity, flame retardancy, anti-skid, wear resistance and other performance characteristics, and are widely laid in kindergartens, swimming pools, sports fields and other places, but the cost is relatively high. Plant straw is cheap, has a wide range of raw materials, has a certain strength, and has a certain ability to combine with rubber, but it has not been used in the production of rubber floor tiles so far.
