[0025] 1. Formula and various materials:

[0026] Formula: The present invention provides an acetophenone-free EVA foaming material, which includes the following chemical components calculated by weight: EVA: 80-100 Phr, foaming agent: 2.0-6.0 Phr, zinc oxide: 2.0-5.0 Phr, stearin Acid: 1.0~1.5Phr, bis-tert-butylperoxydiisopropylbenzene: 0.6~1.0Phr, bis-25 (2,5-dimethyl-2,5-bis(tert-butylperoxy)hexane) : 0.3-0.7Phr, pigment: 1.0-3.0Phr, heavy calcium carbonate: 20-30Phr. See Table 1 for specific ratios.

[0027] Among them, EVA is the grade 18J3 produced by Yanshan Petrochemical, and the content of acetic acid is 18%.

[0028] The blowing agent is azodicarbonamide.

[0029] The filling material is heavy calcium carbonate with a mesh number of 1000-2500 mesh.

[0030] Zinc oxide is zinc oxide prepared by an indirect method with a zinc content of 99.7%.

[0031] 2. Process steps and conditions:

Abstract

The invention discloses an acetophenone-free EVA foam material and a manufacturing method thereof. The acetophenone-free EVA foam material comprises, by weight, 80-100 Phr of EVA, 2.0-6.0 Phr of a foaming agent, 2.0-5.0 Phr of zinc oxide, 1.0-1.5 Phr of stearic acid, 0.6-1.0 Phr of bis(1-(tert-butylperoxy)-1-methylethyl)benzene, 0.3-0.7 Phr of 2,5-dimethyl-2,5-bis(tert-butylperoxy)hexane, 1.0-3.0Phr of a pigment and 20-30 Phr of heavy calcium carbonate. The acetophenone-free EVA foam material is prepared from the bis(1-(tert-butylperoxy)-1-methylethyl)benzene and 2,5-dimethyl-2,5-bis(tert-butylperoxy)hexane, the method adopts a traditional EVA foaming technology, and a result of detection using a liquid chromatogram mass spectrometer / gas chromatograph mass spectrometer shows that the EVAfoam material contains no acetophenone.

Description

technical field [0001] The invention relates to rubber and plastic foaming (molding foaming), in particular to an acetophenone-free EVA foaming material and a manufacturing method thereof. Background technique [0002] Acetophenone, or acetophenone, is an organic compound with the molecular formula C6H5COCH3. It can be used as an intermediate in the manufacture of medicines, resins, flavorings, tear gas, and sleeping pills. At present, acetophenone is mostly obtained as by-products of phenol and acetone by oxidation of cumene, and it can also be obtained by acetylation of benzene with acetyl chloride. [0003] Swallowing acetophenone can produce anesthesia and analgesic effects, and the harm to humans is mainly the stimulation of eyes and skin, which can cause local skin burns and corneal damage. It is harmful to the environment and can cause pollution to the atmosphere. Acetophenone is flammable and has a pungent odor. [0004] EVA foam material is prepared by chemical f...
