Embodiment Construction

[0035] The present invention will be further described below through specific examples, but the examples do not limit the protection scope of the present invention.

[0036] The manufacturing method of the recyclable foaming material of the present invention comprises the following steps:

[0037] 1) Mixing

[0038] The foaming material that can be recycled and used, its chemical composition weight ratio is shown in Table 1; the chemical composition shown in Table 1 is mixed in the internal mixer, and the order of addition is to first mix PP elastomer, anti-shrinkage masterbatch , heavy calcium carbonate and stearic acid are added to the internal mixer and mixed once, and then the foaming agent, peroxide crosslinking agent, crosslinking aid, zinc oxide and pigment are added after the large materials are grouped together, and all the materials are mixed After uniformity, discharge. Moreover, during the feeding process, the temperature should be controlled below 110°C, and par...

Abstract

The invention provides a recyclable foaming material and a preparation method thereof. The recyclable foaming material is prepared from chemical components including, by weight, 70-80 Phr of PP elastomers, 20-30 Phr of anti-shrinking masterbatch, 1.0-4.0 Phr of a foaming agent, 3.0-5.0 Phr of zinc oxide, 1.0-1.5 Phr of stearic acid, 1.5-2.0 Phr of a peroxide cross-linking agent, 1-1.5 Phr of a crosslinking coagent, 1.0-3.0 Phr of pigments and 10-100 Phr of heavy calcium carbonate. Research finds that the foaming material has the 100% recycling property, the very good flexibility, the excellent handfeel and the very good slip resistance, elasticity and compression performance and provides a good direction for preparation of many foaming products such as shoe materials, packaging materials, yoga mats, bath mats, floor mats and outdoor mats.

Description

technical field [0001] The invention relates to a recyclable foam material and a manufacturing method thereof. Background technique [0002] Foaming material refers to the foaming material that can gasify inside the material to generate bubbles to make it a porous material, such as making foam plastic, foam rubber, foam resin and so on. Now that petroleum energy is decreasing, environmental protection and energy issues are becoming more and more concerned. Conventional foaming factories mainly use EVA foaming materials. EVA contains acetic acid, which has a strong odor, is not environmentally friendly, and has poor recycling performance. Contents of the invention [0003] The object of the present invention is to provide a recyclable foaming material and its manufacturing method, the foaming material can be 100% recycled, has high inorganic filling capacity, is conducive to the sustainable development of energy, and has a good It has excellent softness, excellent hand fee...
