Embodiment 1

[0033] Take the following raw materials: 2 kg of trans-isoprene, 8 kg of EVA, 45 kg of iron ore powder, 45 kg of barite powder, 0.5 kg of antioxidant 1010, 0.8 kg of dispersant silicone grease ST-1013, 2 kg of Joint agent A-151 (vinyl triethoxysilane), 5 kg of fumaric acid diester DOF.

Embodiment 2

[0035] Take the following raw materials: 4 kg of trans-isoprene, 5 kg of EVA, 60 kg of iron ore powder, 51 kg of barite powder, 0.6 kg of antioxidant 1010, 0.96 kg of dispersant silicone grease ST-1013, 2.4 kg of Joint agent A-151, 6 kg of fumaric acid diester DOF.

[0036] The preparation process flow chart of present embodiment 1 and 2 is as figure 1 shown. Take the following approach:

[0037] (1) Activate iron ore powder and barite powder, process iron ore powder into 150-300 mesh fine powder, water-select into particles containing 50-70% iron, dewater and dry; barite powder is processed into 200-300 The target powder is dried and dehydrated; the processed iron ore powder and barite powder are mixed, and a coupling agent is added to make active ore powder.

[0038] (2) Put TPI, EVA, and performance additives into the mixer in proportion, mix them evenly and add them to the extruder. High molecular polymer powder pellets are characterized by filling 900-1200% of the fil...

Abstract

The invention discloses a composition used for preparing dumbbells and a dumbbell preparation method using same. The composition comprises the following components according to the parts by weight: 2-4 parts of trans-isoprene, 5-8 parts of ethylene-vinyl acetate copolymer (EVA), 45-60 parts of iron ore powder and 45-60 parts of barite powder and performance additive. The invention also discloses a dumbbell preparation method using the composition. The invention is energy-saving and environmentally friendly; wherein, the preparation method can save more energy materials in the production process and generate no pollution to the environment, and the composition contains no toxic substance and can be recycled. The cast iron substitute prepared by the preparation method has bigger specific gravity with a density of 3-3.5g / m<3> and can satisfy the operating requirement of family fitness equipments.

Description

technical field [0001] The invention relates to a method for preparing fine chemicals, in particular, the invention relates to a composition for preparing dumbbells and a method for preparing dumbbells with the composition. Background technique [0002] At present, the weights of dumbbells and fitness equipment for fitness have been using cast iron materials for many years. Cast iron dumbbells require high-temperature smelting during the production process, which consumes a lot of energy and iron resources, seriously pollutes the environment, does not meet the current national policy requirements, and has a cumbersome manufacturing process and high cost. Contents of the invention [0003] The present invention overcomes the above-mentioned shortcomings, and proposes a composition for preparing dumbbells and a method for preparing dumbbells with the composition. [0004] The composition can also be used in place of other exercise equipment made of cast iron. [0005] The ...
