Embodiment 1

[0026] A manufacturing process of scented rubber products of the present invention comprises the following steps:

[0027] S1. Add the fine rubber powder and softener to the polymer mixer and stir evenly and heat up to 120-220°C. The fine rubber powder and softener are desulfurized at 120-220°C; the particle size of the fine rubber powder is 60-120 mesh; the weight of the softener accounts for 3%-23% of the weight of the fine rubber powder;

[0028] S2, extracting the flue gas produced by the fine rubber powder and softener during the desulfurization process, and adding essence to the fine rubber powder and softener and stirring evenly to obtain scented regenerated rubber powder;

[0029] S3, adding scented reclaimed rubber powder and small chemical materials into the blender to prepare scented mixed rubber;

[0030] S4. Scented rubber products are produced after high temperature and high pressure molding of the scented mixed rubber.

[0031] The invention adopts a non-toxic...

Embodiment 2

[0033] Based on Example 1, the torque of the polymer mixer is 100-500 Nm, and the speed of the polymer mixer is 300-500 r / min. In step S2, a UV photolysis air purifier is used to extract the flue gas produced by the fine rubber powder and softener during the desulfurization process, and to process the flue gas. The rotating speed of the mixer is 100-300r / min. The present invention optimizes the torque and rotational speed of the polymer kneading machine to ensure uniform mixing of fine rubber powder and softener while improving production efficiency. The UV photolysis air purifier is a device that uses a special high-energy and high-ozone UV ultraviolet light beam to irradiate malodorous gas and crack the malodorous gas; the invention can process the malodorous smoke generated by rubber products with high processing efficiency.

Embodiment 3

[0035] Based on the foregoing embodiments, the softening agent includes the following components in parts by weight: 20-30 parts of cottonseed oil pitch, 10-30 parts of soybean oil pitch, 20-30 parts of tall oil pitch, 10-15 parts of palm oil, 5- 15 parts essential oils. The softening agent used in existing tire reclaimed rubber is coal tar, aromatic oil, pine tar, etc., and its disadvantage is that it contains toxic and harmful substances such as benzene, naphthalene, phenol, anthracene, pyridine alkyl aromatic hydrocarbons, etc., and has a strong irritating effect. Nasal odor; the present invention designs a non-toxic and tasteless softener to solve the serious problem of rubber product odor in raw materials. In addition, the present invention adds essential oils, which have fragrance and can improve the taste of rubber products. The total content of eight kinds of PAHs in the softener of the present invention is lower than 10 mg / kg.

Abstract

The invention discloses a scented rubber product manufacturing process. The process includes the following steps: adding fine rubber powder and a softener into a polymer mixing roll for even stirring,raising the temperature to 120-220 DEG C, and desulfurizing the fine rubber powder and the softener at 120-220 DEG C; extracting flue gas produced from the fine rubber powder and the softener in thedesulfurization process, adding essence into the fine rubber powder and the softener, and evenly stirring to obtain scented regenerated rubber powder; adding the scented regenerated rubber powder andchemical small materials into a stirring machine to prepare scented rubber mixture; and performing high temperature and high pressure molding on the scented rubber mixture to obtain the scented rubberproduct. The scented rubber product manufacturing process adds the essence into the mixture of the fine rubber powder and the softener. The essence can replace the odor of rubber power so as to solvethe problem of the odor of conventional rubber products.

Description

technical field [0001] The invention relates to a manufacturing process, in particular to a scented rubber product manufacturing process. Background technique [0002] Rubber products refer to the powdered rubber materials obtained by crushing and desulfurizing waste tires. After adding small chemical materials, after repeated tableting, they are sliced, put into vulcanizers and shaped, and become rubber products. Rubber products are widely used in sports plastic sports fields, playgrounds, rubber floor tiles, seals, auto parts, shoes and other fields. [0003] At present, rubber products are processed into rubber powder from waste tires, made into recycled rubber, added with small chemical materials to make mixed rubber, and made into rubber products after the temperature and pressure of the vulcanizer, because the technology in the recycled rubber process is backward, As a result, the rubber products produced generally have peculiar smell, especially in rubber products su...
