Problems solved by technology

Rubber and leather products are not only not resistant to high temperature, but also not environmentally friendly. Although the appearance is beautiful, the leather production method is cumbersome, and most of the steering wheel covers made of rubber are disposable and do not have the function of recycling

preparation example Construction

[0041] The preparation embodiment of formula I polymer:

[0042]1) In a 250mL round-bottomed three-neck flask, add 1,5-naphthyridine (30mmol), potassium iodide (50mmol), potassium iodate (50mmol) and glacial acetic acid (150mL), stir at room temperature to dissolve, and then heat to 80°C React for 6 hours. Cool to room temperature, filter, and the filter cake is watered successively, saturated with Na 2 CO 3 , saturated Na 2 S 2 o 3 Washed thoroughly with water to obtain a solid product in the form of a white solid.

[0043] 2) In a 100mL round-bottomed three-neck flask, add step 1) product (4mmol), 2-methyl-3-butyn-2-alcohol (12mmol) and NEt 3 (40mL), stirred, pumped twice, then degassed for 30 minutes, added Pd(PPh 3 ) 2 Cl 2 (0.1 mmol), PPh 3 (0.3mmol) and CuI (0.8mmol), heated under reflux to react overnight, TLC showed that the reaction was complete, and the reaction was terminated. Cool to room temperature, filter, and wash the precipitate three times with E...

Embodiment 1

[0052] Such as figure 1 As shown, the outer ring cover body for the steering wheel includes an annular elastic mesh or non-woven fabric ventilation layer 1, and one or more massage parts 2 that are heated, melted, bonded, inlaid or glued on the ventilation layer 1; The massaging member 2 includes a supporting portion 21 and a massaging portion 22 adjacent to each other.

[0053] The setting of the ring-shaped elastic mesh or non-woven fabric ventilation layer 1 of this scheme can increase the friction between the driver's palm and the outer ring casing when driving the vehicle, avoid slipping between the palm and the outer ring casing, and ventilate Layer 1 is made of elastic mesh or non-woven fabric, which can absorb sweat from the palm of the driver and avoid slipping caused by sweat. The elastic mesh or non-woven fabric has air permeability, which increases the air flow while absorbing sweat The circulation of the driver's sweat is alleviated, which not only improves the s...

Embodiment 2

[0064] The outer ring casing body of the steering wheel is the same as in Embodiment 1, the difference is that:

[0065] In step (1), apply a release agent to the mold of the massage part before casting, and control the heating temperature at 25°C. The particle size range of additives is 0.8-5 microns; among them, the particles of 0.8-1 microns account for 40% of the total weight of solid additives; the particles of 1-2 microns account for 30% of the total weight of solid additives; the balance of particles of 5 microns ;

[0066] The second cooling temperature in step (3) is 50°C.

Abstract

The invention relates to an outer ring cover body of a steering wheel. The outer ring cover body of the steering wheel comprises annular elastic mesh cloth or a non-woven fabric ventilation layer and one or more massage parts which stick to the ventilation layer through heating melting or are connected to the ventilation layer in an embedded mode or stick to the ventilation layer through adhesives; each massage part comprises a support portion and a massage portion which are connected with each other in an adjacent mode. The preparation method of the outer ring cover body of the steering wheel comprises the following steps that after curing agents and additives are added in resin, the resin is sprayed into models of the massage parts, and the massage parts are obtained through casting; the elastic mesh cloth is fetched, pressurized bonding is conducted on the elastic mesh cloth and the massage parts through high temperature heat treatment, and a first outer ring cover body is obtained; secondary cooling is conducted on the first outer ring cover body to obtain the outer ring cover body used for the steering wheel. According to the scheme, the manufacturing process is simple, the product is easy to obtain, the safety coefficient of the manufactured product is high, and the outer ring cover body of the steering wheel is attractive and suitable for being applied and popularized on a large scale.

Description

technical field [0001] The invention relates to the field of manufacturing steering wheel covers, in particular to an outer ring cover body of a steering wheel. Background technique [0002] Steering wheel covers currently on the market are mostly rubber or leather products. For example, a steering wheel cover disclosed by the announcement number CN203727453U (2014-07-23) includes a steering wheel cover body that can completely cover the steering wheel. The inner side of the cover body is provided with a cladding layer, and the cladding layer is filled with automobile deodorant, and the outer material of the steering wheel cover body is leather. Rubber and leather products are not only not resistant to high temperature, but also not environmentally friendly. Although the appearance is beautiful, the leather production method is cumbersome, and most of the steering wheel covers obtained from rubber are disposable and do not have the function of recycling.
