Problems solved by technology

[0003] Disadvantages in the existing technology: 1. Use waste rubber and waste tires to produce rubber floor tiles. The bottom layer mainly uses 1mm-5mm rubber particles, and the surface layer uses about 1mm Add toner dyeing to make rubber floor tiles, and use the molding technology room to solidify naturally
The disadvantages of this kind of product are easy to fade, and the shrinkage gap is very large (generally about 2mm-3mm)
Easy to warp, single color, easy to drop particles, color difference, short service life
Difficult to clean, limited use space

preparation example Construction

[0038] A kind of phantom rubber floor mat, its manufacture method comprises the following steps:

[0039] (1) Production of bottom particles:

[0040] The waste rubber is crushed, sieved, and dedusted to obtain rubber particles with a particle size of 0.5-5mm, which are the bottom particles;

[0041] (2) Bottom production:

[0042] 1) Fully mix the bottom layer particles prepared in (1) with the adhesive;

[0043] 2) Pour the well-mixed granules into the mold, pave them flat, then heat and pressurize the granules at 160-200°C and 0.4-0.6MPa for 5-7 minutes to form the granules, cool to room temperature, take them out from the mold, and slice into pieces The sheet of the required specification is the bottom layer;

[0044] (3) Production of surface particles:

[0045] 1) Weigh 20-25 parts of EPDM rubber, 7-10 parts of rubber oil, 4-5 parts of toner, 6-8 parts of white carbon black, 0.8-1.2 parts of anti-ultraviolet agent, 0.8 parts by weight. ~1.2 parts accelerator, 0.8~1....

Embodiment 1

[0062] Purchase rubber scraps from rubber product factories (such as rubber sole factories, etc.) and waste tires, car tires, etc., and screen these waste rubber, and then undergo coarse crushing, medium crushing, fine crushing, sub-sieving, and dust removal to obtain a particle size of 0.5~ 5mm rubber granules, as the bottom granule material;

[0063] (2) Bottom production:

[0064] 1) Weigh 85 parts by weight of the bottom layer particles prepared in (1), 15 parts of adhesive vinyl chloride resin, stir repeatedly for 5 minutes, and mix well;

[0065] 2) Pour the uniformly mixed granules into a mold with a length of 502mm, a width of 502mm, and a height of 20mm, spread it evenly, and place it in a professional oven to heat and pressurize the material in the mold at 180°C and 0.5 MPa for 7 minutes. Shape the particles, take them out of the oven and cool them down to a constant temperature in the room, and then take them out of the mold to obtain a bottom layer with a size of ...

Embodiment 2

[0077] Purchase rubber scraps from rubber product factories (such as rubber sole factories, etc.) and waste tires, car tires, etc., and screen these waste rubber, and then undergo coarse crushing, medium crushing, fine crushing, sub-sieving, and dust removal to obtain a particle size of 0.5~ 5mm rubber granules, as the bottom granule material;

[0078] (2) Bottom production:

[0079] 1) Weigh 80 parts by weight of the bottom layer particles prepared in (1), 15 parts of adhesive pure acid resin paint, stir repeatedly for 5 minutes, and mix well;

[0080] 2) Pour the uniformly mixed granules into a mold with a length of 502mm, a width of 502mm, and a height of 20mm, spread it evenly, and place it in a professional oven to heat and press the material in the mold at 200°C and 0.6MPa for 5 minutes. Shape the particles, take them out of the oven and cool them down to a constant temperature in the room, and then take them out of the mold to obtain a bottom layer with a size of 500 (...

Abstract

The invention discloses a colorful rubber floor mat and a manufacturing method of the colorful rubber floor mat. The manufacturing method of the colorful rubber floor mat includes the steps that waste rubber is smashed to serve as bottom-layer particles, then the smashed waste rubber and adhesives are evenly mixed, and a molded bottom layer is formed in a heated and pressurized mode; raw materials including ethylene-propylene-diene monomer, rubber oil, toner, white carbon black, ultraviolet-resistant agents, accelerants, zinc oxide, antioxidants, calcium carbonate and the like are evenly mixed, banburying and open milling are sequentially carried out, rubber is cut into pieces, the rubber pieces are cooled and smashed to serve as face-layer particles, then the smashed rubber pieces and adhesives are evenly mixed, and a molded face layer is formed in a heated and pressurized mode; finally the bottom layer and the face layer are bonded with the hot mold technology. The service life of the colorful rubber floor mat manufactured with the manufacturing method is as long as 5 years-8 years; the colorful rubber floor mat can be resistant to the 180-DEG C high temperature; the buffering performance is good; a slightly-protruding particle feeling is achieved on the surface, a special soft feeling is achieved during treading, and the colorful rubber floor mat has the elasticity and is resistant to sliding; no harmful matter is contained; the colorful rubber floor mat is basically free of influences of expansion caused by heat and contraction caused by cold, and is safe, comfortable, durable and attractive in appearance.

Description

technical field [0001] The invention belongs to the field of rubber industry and relates to a magic color rubber floor mat and a manufacturing method thereof. Background technique [0002] According to statistics, 50,000 automobile tires are scrapped every day in the world, and more than 50,000 tons of other rubber products are scrapped every day, and waste rubber has become garbage. These rubbish not only occupy land resources but also easily breed mosquitoes and cause serious environmental pollution. Disposal of waste rubber is limited to landfill. The time is short and the waste rubber is not easy to rot. It takes 30 years to rot waste rubber, which is a long cycle and slow to take effect. Solving the world's increasingly prominent problem of exhaust rubber has attracted great attention from various countries in the world. There are also many countries that now provide subsidies to manufacturers that are capable of processing waste tires and waste rubber. Recycling ...
