Problems solved by technology

[0002] Existing PVC skins can be used as steering wheel covers for car seats, and seat cushions for motorcycles and bicycles, etc. after being processed and formed, sunlight can be classified into three types: visible light, ultraviolet rays, and infrared rays according to wavelengths, of which infrared rays have a stronger Penetration and radiation force have significant temperature control effect and resonance effect. It is easily absorbed by the object and converted into the internal energy of the object. After the object absorbs infrared light, the temperature of the object rises and the generated temperature is emitted outward. Therefore Infrared rays are the main source of heat, so if the car is parked outdoors in summer, the surface temperature of the seat cushion will rise after being irradiated, and people will feel uncomfortable sitting on the seat cushion

Embodiment 1

[0027] Example 1: When preparing low heat-absorbing adhesive tape, mix 100 PHR of PVC powder, 20-120 PHR of plasticizer, 1-10 PHR of stabilizer, 0-10 PHR of modifier, and 0-50 PHR of filler , 1-30 PHR infrared pigments are put into a 10,000-horsepower machine for mixing into a semi-finished product in the shape of a melted rubber block, and then the semi-finished product is put into a two-roller rolling machine for full turning, so that the semi-finished product is mixed more evenly and the degree of gelatinization is improved. Higher, the front, upper, middle and lower speed ratios of the rolling mill are 1: (1.25~1.35): (1.28~1.38): (1.:31~1.41), and the semi-finished products are pressed into the required Thickness, form PVC film, emboss the PVC film with the embossing wheel of the embossing machine, then cool the embossed PVC film to form a low heat-absorbing adhesive tape, and wind the low-endothermic adhesive tape with a coiler .

Embodiment 2

[0028] Example 2: When preparing low heat-absorbing foam tape, fill 100 PHR of PVC powder, 20-120 PHR of plasticizer, 1-10 PHR of stabilizer, 0-10 PHR of modifier, and 0-50 PHR of filling agent, foaming agent less than or equal to 20 PHR, and infrared colorant of 1 to 30 PHR are put into a 10,000-horsepower machine for mixing into a semi-finished product in the shape of a melted rubber block, and then the semi-finished product is put into a two-roller rolling machine for full turning , so that the semi-finished product is mixed more evenly and the degree of gelatinization is higher. The front, upper, middle and lower speed ratio of the rolling mill is 1: (1.25~1.35): (1.28~1.38): (1.:31~1.41), and The semi-finished product is pressed into the required thickness by a rolling machine to form a PVC film, and the PVC film is sent to the foaming furnace with the conveyor network equipment, and the PVC film is preheated before the foaming furnace, and the PVC film is sealed with a la...

Embodiment 3

[0029] Example 3: When preparing low heat-absorbing rubber, mix 100 PHR of PVC powder, 20-120 PHR of plasticizer, 1-10 PHR of stabilizer, 0-10 PHR of modifier, and 0-50 PHR of filler , 1-30 PHR infrared pigments are put into a 10,000-horsepower machine for mixing into a semi-finished product in the shape of a melted rubber block, and then the semi-finished product is put into a two-roller rolling machine for full turning, so that the semi-finished product is mixed more evenly and the degree of gelatinization is improved. Higher, the front, upper, middle and lower speed ratios of the rolling mill are 1: (1.25~1.35): (1.28~1.38): (1.:31~1.41), and the semi-finished products are pressed into the required Thickness, form PVC film, paste PVC film to base fabric, base fabric is sent with sending frame, base fabric is coated with TPR lower molecular weight solution or PU paste on the base fabric as adhesive when laminating, use The tape machine is calendered and the base cloth is lam...

Abstract

The invention discloses a low heat absorption PVC product and a method of preparing adhesive tapes and the rubber sheets from it. The low heat absorption PVC product involved in the invention comprises: 100PHR of PVC powder, 20-120PHR of a plasticizer, 1-10PHR of a stabilizer, 0-10PHR of a modifier, 0-50PHR of a filling agent, 0-20PHR of a foaming agent, and 1-30PHR of an infrared pigment. The prepared products fall into ordinary products and foamed products. The foaming agent is not needed in the ordinary products, and the foaming agent needs to be added in the foamed products. For the PVC product disclosed in the invention, the infrared pigment is added into the PVC powder, so that the PVC product has the advantage that it can reflect infrared rays irradiated from the sunlight so as to lower the temperature of an object.

Description

technical field [0001] The invention relates to a low heat-absorbing PVC product and a method for preparing adhesive plasters and rubber sheets using the same. Background technique [0002] Existing PVC skins can be used as steering wheel covers for car seats, and seat cushions for motorcycles and bicycles, etc. after being processed and formed, sunlight can be classified into three types: visible light, ultraviolet rays, and infrared rays according to wavelengths, of which infrared rays have a stronger Penetration and radiation force have significant temperature control effect and resonance effect. It is easily absorbed by the object and converted into the internal energy of the object. After the object absorbs infrared light, the temperature of the object rises and the generated temperature is emitted outward. Therefore Infrared rays are the main source of heat generation, so if the car is parked outdoors in summer, the surface temperature of the seat cushion will rise aft...
