Embodiment 1

[0023] (1) Take the ore sand and wash it, then transfer it to an oven, and control the temperature at 150°C for drying; take 100Kg of ore sand, 5Kg of polyurethane Pu, 0.8Kg of titanium dioxide, 4Kg of PTA, and 2Kg of EG, and stir at room temperature. The above materials are gradually coated on the ore sand Surface, after finally getting white ore sand with uniform color, stop stirring; control the temperature to bake the above white ore sand at 120°C, turn over 10 times per minute, finish drying, and cool to room temperature.

[0024] (2) Take waste automobile tires and crush them, screen them into 18-22 mesh rubber particles, add polyurethane Pu to the crushed rubber particles, mix and stir, put them into a pattern mold, and prepare a door mat base under the conditions of a pressure of 15MP and a temperature of 150°C. Leave the base of the door mat to cool;

[0025] (3) coat polyurethane Pu layer on the doormat base that above-mentioned preparation is completed, this polyure...

Abstract

The invention discloses a method for preparing a heat transfer sand-planted door mat. The method comprises the following steps of: (1) crushing waste automobile tires into rubber grains with the granularity of 18-22 meshes, mixing and stirring the rubber grains and polyurethane PU, putting into a pattern mold, and preparing a door mat matrix at the temperature of 150DEG C under the pressure of 15MPa; (2) coating PU on the door mat matrix, planting ore sand which is processed by PU, drying at the temperature of 120DEG C for 35 to 45 minutes, taking out, and cooling to room temperature; and (3) feeding the door mat matrix which is planted with sand into a transfer machine, performing heat transfer by covering the processed transfer paper, and obtaining door mat with various patterns. The ore sand representing patterns is coated with a polyester-like material, so that the ore sand has textile properties and is suitable for a heat transfer technology; therefore, a problem that a sand-planted door mat is single in color is solved, and patterns are bright and vivid; and moreover, waste gas and waste water are not generated and the product is safe and environment-friendly.

Description

technical field [0001] The invention relates to a sand-planting door mat, in particular to a sand-planting door mat produced by thermal transfer technology. Background technique [0002] Door mats are daily necessities that can effectively absorb dust and sewage and keep the interior clean. Traditional door mats are mainly made of fibers, PVC, and rubber. The door mats made of these materials either have low dust absorption ability, or have little effect on removing sewage, and cannot effectively recycle and absorb dust and sewage. The use function of the door mat is reduced, and the cost is higher. At the end of the last century, foreign countries began to use waste vehicle tires as raw materials to make door mats. On the one hand, it will not cause harm to the human body, and on the other hand, it solves the pollution caused by waste tires to the environment. [0003] At the beginning of this century, the use of waste vehicle tires to make doormats began to mature. Over ...
