Problems solved by technology

[0005] In the above-mentioned waste rubber powder floor tile preparation technology, the adhesive used is a reactive adhesive, and its limited reaction and curing time brings time constraints to operations before curing such as material mixing and mold filling.
In addition, the cost of these binders is relatively high, which affects the cost performance of waste rubber powder road tiles to a certain extent.

Embodiment 1

[0025] Take 19.8% SBR rubber block, chop it into rubber particles with a particle size of about 1cm, put it into 79.2% petroleum heavy distillate oil with a distillation range of 510~600°C, and stir it at 180°C After uniformity, cool the material down to 160°C, add 1% sulfur vulcanizing agent (sublimed sulfur content >98.5%) and accelerator TMTD (mass ratio of vulcanizing agent is 2:3), stir evenly, and keep the temperature at 160°C After 1 hour, a lightly vulcanized rubber adhesive was obtained.

[0026] Heat 16.7% adhesive to 180°C molten state, stir evenly with 83.3% 180°C waste rubber powder (20 mesh), and fill it into a mold that has been preheated to 180°C with a release agent inside (internal The size is 50cm in length, 50cm in width, and 8cm in depth). After filling and scraping, cover with a 25kg compaction cover (which has been preheated to 180°C and coated with a release agent), and put it in a 180°C environment box for health preservation 1 Hours later, after taki...

Embodiment 2

[0028] Heat 19.9% ​​styrene-butadiene rubber block and 79.9% petroleum heavy distillate oil with a distillation range of 480~540°C to 160±2°C, and add them to the twin-screw extruder. The temperature of the extruder is controlled at 160±2°C. Add 0.2% dicumyl peroxide and ZnO (the mass ratio of dicumyl peroxide and ZnO is 1:1) to the rubber mixture extruded by the extruder, and stir After uniformity, keep the temperature constant for 1 hour to obtain shallow vulcanized rubber adhesive.

[0029] Stir and mix 20% binder, 78% waste rubber powder (80 mesh) and 2% fiber material (the amount of fiber material is based on the total weight of binder and waste rubber powder) at 170°C , filled into a 170°C mold coated with a release agent (the internal dimensions are 40cm in length, 30cm in width, and 12cm in depth), after filling and leveling, cover with a 15kg compaction cover (preheated to 170°C and Coated with a release agent), put it in a 170°C environment box for 1 hour, take it o...

Abstract

The invention discloses a waste rubber powder floor tile and a making method thereof. The waste rubber powder floor tile comprises the following components by weight percentage: 55%-92% of waste rubber powder, and 7%-40% of a light vulcanized rubber adhesive. Specifically, the light vulcanized rubber adhesive contains, by weight percentage, 3%-24% of rubber, 0.2%-3% of a vulcanizing agent, and 75%-96% of heavy distillate oil of petroleum. The preparation method comprises: stirring the molten state light vulcanized rubber adhesive and waste rubber powder evenly, filling a floor tile mould with the mixture, then conducting curing and cooling, and disassembling the mould, thus obtaining the waste rubber powder floor tile. The waste rubber powder floor tile provided by the invention has a self-repair function, the material cost is low, and the preparation process is not limited by the operating time.

Description

technical field [0001] The invention relates to a waste rubber powder floor tile for road paving and a preparation method thereof. Background technique [0002] In order to improve the performance of pavement paved with road floor tiles made of cement, slag and other materials in the past, people began to use waste rubber powder to produce road floor tiles. The pavement paved with road floor tiles made of waste rubber powder has the flexibility of rubber, and the feet feel comfortable, which can reduce the trauma caused by human falls. Compared with polyurethane plastic floor materials, waste rubber powder is a relatively cheap human-friendly road floor material. [0003] KR100172473 discloses a human-friendly road floor tile, which adopts latex adhesive and vulcanizing agent to bond brick body materials. KR1020060080112 discloses a waste rubber floor tile, which uses polyurethane as an adhesive to bond materials such as waste rubber powder and pigments. The floor tile has...
