Problems solved by technology

At present, yoga balls made of soft PVC materials have the following defects: 1) the ball is thin; 2) the surface of the ball is not delicate; There are security risks
However, after the chemical foaming agent foams, the bubbles produced are many and uneven in size, which easily leads to uneven distribution of pores inside the sphere, resulting in uneven density of the sphere. affect its user experience

preparation example Construction

[0032] The preparation method of the medium-high temperature heat-expandable microspheres comprises the following steps:

[0033] The expandable substance and the polymerizable compound containing polymerizable monomers are kept in suspension by continuous stirring or adding a dispersion stabilizer, and after suspension polymerization, they are filtered, washed and dried to obtain the medium-high temperature thermally expandable microspheres.

Embodiment 1

[0035] A kind of composite material for fitness yoga ball, is made up of the following components in parts by mass: 50 parts of pasty PVC resin powder, 15 parts of TPU, plasticizer (dioctyl phthalate and dibutyl phthalate 30 parts of ester (1.5:1 compound), 1 part of stabilizer, 1 part of viscosity reducer, 2 parts of medium temperature expandable microspheres (particle size 20-30 μm), 5 parts of pigment.

[0036] Add the raw materials of each component into the mixer in proportion, and adjust the set temperature of the mixer according to the use temperature of the medium-temperature expandable microspheres, and the set temperature is 100°C. Then the uniformly dispersed raw materials were poured into the mold of the rotational molding machine, and the temperature in the mold was set to 140°C.

Abstract

The invention provides a composite material for fitness yoga balls and a preparation method thereof. The composite material for the fitness yoga balls is prepared from the following components in parts by weight: 50 parts of pasty PVC resin powder, 15-30 parts of a thermoplastic polyurethane elastomer (TPU), 30-50 parts of a plasticizer, 1-3 parts of a stabilizer, 1-3 parts of a viscosity reducer,2-10 parts of a moderate and high temperature thermal expansion microballoon and 5-10 parts of pigment. According to the composite material for fitness yoga balls and the preparation method thereof,through a TPU and pasty PVC alloying technology, the hardness of a formula product can be reduced, and the elasticity of the yoga balls is improved. The expandable microballoon is added, the dosage ofthe pasty PVC resin powder can be obviously reduced, meanwhile, the dosage of the plasticizer is further obviously reduced, the thickness of a ball body can be kept invariable or increased, the ballbody surface of the prepared fitness yoga balls is fine and smooth, bumps with uniformly distribution are formed in the surface, as the fitness yoga balls have higher buffering performance, when the fitness yoga balls touch sharp objects accidently, the yoga balls are in a slow staleness process, potential safety hazards do not exist, and the problem of explosion proofing is solved.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and in particular relates to a composite material for fitness yoga balls and a preparation method thereof. Background technique [0002] Yoga ball is a kind of ball sports tool for shaping and fitness. The material is mostly made of soft PVC material. When the human body is in contact with it, the inflated fitness ball inside will evenly touch the contact parts of the human body to produce a massage effect. Strong elasticity, good for promoting blood circulation. There are many benefits to using yoga balls, which can help people effectively strengthen their bodies, slim their bodies and shape, achieve weight loss effects, and perform a good massage on the human body to relieve tension. At present, yoga balls made of soft PVC materials have the following defects: 1) the ball is thin; 2) the surface of the ball is not delicate; There are security risks. [0003] At present, in the pr...
