In order to further understand the structural features of the present invention, the use of technical means, and the expected effects, the manner of use of the present invention is described. It is believed that the deeper and specific understanding of the present invention can be obtained as follows:

Please continue to refer to FIG. 2 and refer to FIG. 3. The present invention first uses the first infusion device 20 to form the dough 28, and cools the dough 28 using the cooling device 30 when it is not fully reacted, and then When the cover 28 has not fully reacted and is tacky, the second infusion device 50 is used to mold the substrate 53, and finally the base cloth 61 is attached to the substrate 53 through the winding device 60 to obtain the finished product 70. .

The first mixture of the present invention controls the output of the first material tanks 21 through the control device 23, so that the first mixture can react with moisture and moisture in the air because it contains NCO 2-15% by weight. It gradually hardens and forms a stable state, and has high stability, high storage and high stability, so it can be processed into the skin 28, and if the first mixture contains NCO of 2 wt% or less, it cannot be stored and reduced. Disadvantages of stability and high viscosity cannot be processed into the crust 28. In addition, if the first mixture contains more than 15 wt% NCO, the first mixture will be easily affected by moisture and unstable, and the unstable system will generate cracks, for example. , Reduced hardness or reduced elasticity.

According to the present invention, the first mixture is applied to the release paper 11 at a temperature of 50 ^O C to 150 ^O C through the output control unit 27, so that the first mixture can maintain high stability and high storage. If the temperature is higher than 150 ^O C, the first mixture will be deteriorated. If the temperature is lower than 50 ^O C, the viscosity will be reduced and the cover sheet 28 cannot be formed on the release paper 11.

The present invention first forms the skin 28, and after passing a distance in parallel, then uses the measuring member 291 to measure the thickness of the skin 28, and increases or decreases the output of the output control unit 27 with the output control unit 27 to make the skin The thickness of 28 is between 10 um and 2 mm, so that the first mixture can gradually react within a predetermined time, and the chain 28 of the macromolecules is formed into the dough. If the thickness is greater than 2 mm, the reaction time will increase. And the middle will maintain a high temperature state, reducing the quality of the skin 28. If the thickness is less than 10 um, the skin 28 is not effective.

It is worth mentioning that the noodle 28 is bridged by the water and air of the air, and by controlling the temperature and thickness of the coating of the first mixture. At the same time, no solvent, catalyst or oven is used in the process of erecting overseas Chinese. Therefore, It can gradually react and become a polymer, so it has good physical properties and can withstand high temperatures.

The present invention cools the noodle 28 which is not fully reacted through the cooling zone 31 so that the temperature of the noodle 28 is between 5 ^O C and 15 ^O C, reduces its viscosity and flattens through the rolling group 40.

According to the present invention, the substrate 53 is formed on the surface 28 by using the second infusion device 50. Since the substrate 53 contains a foaming agent of 0.01 wt% to 0.5 wt%, and the foaming agent is selected from hydroxyl groups containing OH Compound, water or solid foaming agent, because the skin 28 absorbs an appropriate amount of water vapor through the NCO containing more than 15 wt%, and the skin 28 is viscous when the skin 28 is not fully reacted, the substrate 53 is formed. At this time, a bridging reaction will be generated between the cover 28 and the substrate 53 to form a unity.

Finally, when the base material 53 has not fully reacted and is tacky, the base fabric 61 is adhered to the top surface of the base material 53 so that the base fabric 61 and the base material 53 are completely combined into one body to complete the finished product.

It is worth mentioning that there is no added solvent in the manufacturing process of the present invention, so there is no environmental pollution and no added catalyst, so there is no environmental toxicity, and no need to use an oven, so it can achieve the role of energy saving and carbon reduction, and reduce emissions. Carbon footprint.

Hereby, the features of the present invention and the expected effects that can be achieved are stated as follows:

It is worth mentioning that the noodle 28 is bridged by the water and air of the air, and by controlling the temperature and thickness of the coating of the first mixture. At the same time, no solvent, catalyst or oven is used in the process of erecting overseas Chinese.
