Embodiment 1

[0027] A high wear-resistant car mat material, made of the following raw materials by weight: 38 parts of EPDM rubber, 33 parts of polyurethane, 17 parts of nano filler, 9 parts of carbon black, 4 parts of glass fiber, phthalic acid Dioctyl ester 3.5 parts, paraffin oil 3 parts.

[0028] The preparation method of described nanofiller comprises the following steps:

[0029] (1) Use a graduated cylinder to measure 4.5ml of aminopropyltriethoxysilane and 30ml of ethyl acetate, put them under a fume hood, and add them to the beaker together. At 20-25°C, place the beaker in a magnetic stirring device Stir at a speed of 300-350 rpm. After stirring for 10-15 minutes, weigh 1.25g of zinc oxide, add it to the beaker while stirring, continue stirring for 20-30 minutes, ultrasonic treatment for 10 minutes, and then at 40-45°C Stand still for 200-250min, filter, dry the obtained filtrate at 60-70°C and place it in a muffle furnace for calcination, the calcination temperature is 700-720°C...

Embodiment 2

[0044] A high wear-resistant car mat material, made from the following raw materials by weight: 38 parts of EPDM rubber, 35 parts of polyurethane, 20 parts of nano filler, 10 parts of carbon black, 3.6 parts of glass fiber, phthalic acid 3.8 parts of dioctyl esters, 3 parts of paraffin oil, the processing mode of raw material is the same as embodiment 1.

Embodiment 3

[0046] Compared with Example 1, the carbon nanotubes are not specially treated.

Abstract

The invention relates to a high wear resistant automobile foot pad material prepared from the following raw materials by weight: 35-40 parts of ethylene-propylene-diene monomer, 30-35 parts of polyurethane, 15-22 parts of a nano-filler, 8-10 parts of carbon black, 3-4 parts of glass fibers, 3-4 parts of dioctyl phthalate, and 2-3 parts of paraffin oil. An automobile foot pad provided by the invention adopts the ethylene-propylene-diene monomer and polyurethane as base rubber; by addition of the nano-filler and the glass fibers for compositing, a traditional reinforcing method using a large amount of carbon black is changed; the novel nano-filler is used for increasing the crosslinking points of rubber; meanwhile, the bonding points of carbon black, the nano-filler and rubber are significantly increased due to good dispersity of the filler, a space network structure is formed, and the strength, wear resistance and aging resistance of the rubber are effectively enhanced.

Description

technical field [0001] The invention belongs to the field of automobile materials, and in particular relates to a highly wear-resistant automobile floor mat material. Background technique [0002] The car floor mat is an environmentally friendly car interior component that integrates the five main functions of water absorption, vacuuming, decontamination, sound insulation, and protection of the main blanket. Car floor mats are interior decorations, which protect the cleanliness of the inside and outside of the car, and play the role of beautiful and comfortable embellishment. [0003] Water absorption, vacuuming and decontamination of car floor mats can effectively prevent the residual moisture and dirt on the soles from sliding between the clutch, brake and accelerator, avoid safety hazards, and reduce the possibility of contamination and damage to the interior. After all, clean the floor mats It is more convenient and economical than cleaning the interior. However, the f...
