preparation example Construction

[0044] A kind of preparation method as above-mentioned latex material, comprises the following steps:

[0045] Mix natural rubber latex, aromatic plant essential oil microcapsules, vulcanizing agent, accelerator and anti-aging agent, and stir evenly; and molding, vulcanization and setting, demoulding, chlorination, boiling, leaching and drying to obtain latex material.

[0046] Preferably, the stirring speed is 100-300rpm, such as 100rpm, 150rpm, 200rpm, 250rpm or 300rpm, etc.; the stirring time is 0.5-4h, such as 0.5h, 1h, 1.5h, 2h, 2.5h, 3h, 3.5 h or 4h etc.

[0047] Preferably, the vulcanization temperature is 60-110°C, such as 60°C, 70°C, 80°C, 90°C, 100°C or 110°C.

[0048] The drying described above further increases the degree of vulcanization. The drying is preferably hot air drying, and the drying temperature is 60-85°C, such as 60°C, 65°C, 70°C, 75°C, 80°C or 85°C.

[0049] It should be noted that sealing and packaging the latex material (such as rubber tube or fi...

Embodiment 1

[0052] (1) In terms of parts by mass, 5 parts of microencapsulated aromatic plant essential oils (the plant essential oils contain lavender essential oil and jasmine essential oil in a ratio of 2:1), 3 parts of sulfur, 5 parts of zinc oxide, and 3 parts of promoting Add agent ZDC and 3 parts of anti-aging agent to 100 parts of natural rubber latex together, use mechanical stirring, stir at a stirring speed of 300rpm for 0.5h, disperse it evenly in natural rubber latex, and set aside;

[0053] (2) According to the conventional method at room temperature, the square aluminum plate impregnated with a coagulant (its main components are calcium nitrate and bentonite) is immersed in the above-mentioned latex for a certain period of time, so that the latex is solidified and formed on the surface of the square aluminum plate to reach the required thickness. Then take it out, and then place the whole mold in a hot air oven at 110°C for 30 minutes to vulcanize and shape, and then go thro...

Abstract

The invention discloses a latex material capable of releasing fragrance, a preparation method and an application thereof. The latex material comprises the following raw material components in parts by weight: 100 parts of natural latex, 0.1-5 parts of fragrant plant essential oil microcapsule, 0.5-3 parts of vulcanizing agent, 1-5 parts of active agent and 0.5-3.0 parts of accelerants. A leisure fitness instrument which is prepared from the latex material provided by the invention can promote the nerve soothing and relieve the pressure because the fragrant plant essential oil microcapsule is contained and is capable of releasing the pleasant fragrant odor for a long time.

Description

technical field [0001] The invention relates to the technical field of latex material research, in particular to a latex material emitting fragrance and its preparation method and application Background technique [0002] In recent years, with the rapid improvement of people's living standards and the increasing awareness of health, the leisure and fitness equipment industry is ushering in a spring of vigorous development. Natural rubber latex has the characteristics of excellent tensile strength, super high elasticity, and elongation at break of more than 700%. It is the best elastic material for fitness equipment. A series of leisure and fitness equipment prepared from natural latex through various special processes, such as latex tensioners, yoga tension belts, etc., have bright and colorful colors, high tensile strength, high stretching multiples, excellent resilience, and good anti-aging properties. features. Compared with traditional spring-type tensioners or cotton ...
