Problems solved by technology

[0006] This kind of operation steps can only achieve simple bonding and superposition of rubber products and polyurethane products, but cannot solve the shortcomings of rubber use. The oil resistance and solvent resistance of rubber are still poor, and the glue brushing process not only increases the operation steps, Moreover, the labor cost is increased, which makes the production cost of the product higher; in addition, the soles made of traditional techniques, after being made into shoes, are prone to failure due to the glue, which affects the service life of the shoes
[0007] And the preparation device used in the preparation process of rubber-polyurethane composite products, such as the mixing device, also has the main problem of uneven mixing and stirring, and there is no extrusion mechanism, resulting in insufficient elasticity of the rubber-polyurethane material, which seriously affects Production quality; in addition, the preheating and cooling function of the mold used for rubber-polyurethane composite products is not obvious, which may easily lead to cracks on the surface of the product, resulting in poor product performance, and cracks on the surface are prone to affect the quality of the product. In addition, the mold is heated and cooled It takes up a lot of space, and the mold is easy to deform, which seriously affects the service life; after the rubber-polyurethane composite material is injected, the trimming device used in the process of trimming the rubber-polyurethane composite product has poor adaptability, and cannot adapt to the unevenness of the product surface. , resulting in a limited range of use

Embodiment 1

[0055] as attached figure 1 Shown, the invention provides a kind of preparation method of rubber-polyurethane composite product, comprises the steps:

[0056] The first step is to cut and crush the rubber raw material components. The crushed rubber raw materials are melted in a segmental temperature environment, and the additives are mixed and proportioned in the melted rubber raw materials by the drop method, and the rubber products are obtained by uniform stirring and extrusion. In the present invention, the specific mixing ratio of the additive and the rubber raw material is 3 / 20-3 / 10, and the additive is mixed and stirred with the rubber raw material by the drop method, which can improve the mixing uniformity between the additive and the rubber raw material, thereby improving the rubber product. the quality of.

[0057] It should be added that in the present invention, the additives include 10-15wt% accelerator, 15-30wt% pigment, 10-25wt% zinc oxide, 25-40wt% blowing agen...

Embodiment 2

[0078] Based on the above preparation method, the present invention also provides a rubber-polyurethane composite product preparation device, which is composed of a multifunctional mixing device, a product mold and processing and trimming equipment. The multifunctional mixing device is mainly to obtain rubber products and polyurethane products, and then mix and hammer the rubber products and polyurethane products to obtain rubber-polyurethane composite materials, extrude the rubber-polyurethane composite materials into the product mold for stamping and shaping, and shape The completed product is demolded and trimmed to obtain a complete rubber-polyurethane composite product.

[0079] as attached figure 2As shown, wherein, the multifunctional mixing device includes a rubber melting mechanism 1 and a polyurethane melting mechanism 2, and the rubber melting mechanism 1 and the polyurethane melting mechanism 2 are jointly connected with a secondary extrusion mechanism 3, that is ...

Abstract

The invention discloses a preparing method of a rubber-polyurethane composite product and a machining trimming device. The method comprises the following steps that a smashed rubber raw material is melted under the environment with the segmented temperature, during melting, a matching additive is mixed, and stirring and extrusion are carried out; a smashed polyurethane raw material is melted underthe environment with the segmented temperature, during melting, a matching accelerant is mixed, and stirring and extrusion are carried out; a rubber product and a polyurethane product are mixed according to the proportion, and a rubber-polyurethane composite material is stirred and extruded in a heat preservation cavity; the stirred and extruded rubber-polyurethane composite material is subjectedto heating sulphur treatment and stamping shaping; a grinding disc grinds the side faces and the surface of the rubber-polyurethane composite material product, and trimming precision processing is achieved; the products of different sizes can be clamped, the side faces and the surfaces of the products can be ground, the use range is widened, operation is easy, the grinding disc can achieve heightself compensation, and in the grinding process, concave and convex characteristics of the products can be prevented from being damaged.

Description

technical field [0001] The invention relates to the technical field of rubber-polyurethane composite products, in particular to a preparation method and processing and trimming equipment for rubber-polyurethane composite products. Background technique [0002] The biggest advantage of composite rubber products is the strength of various materials, such as high strength, light weight, high and low temperature resistance, corrosion resistance, heat insulation, insulation and other properties. According to the application purpose, select polymer materials and other materials with special properties. into a composite material that meets the needs. [0003] Rubber refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature, can produce large deformation under a small external force, and can return to its original shape after the external force is removed. Rubber is a completely amorphous polymer. Its glass transition temperature is ...
