Embodiment 1

[0018] A durable vehicle-mounted sintered PE aromatherapy tablet is prepared by the following steps:

[0019] (1) Add baking soda to the 100-mesh ultra-high molecular weight polyethylene powder obtained by sieving, stir well and preheat the mold at 135 °C for 80 minutes in the first stage, then turn to 175 °C for sintering for 75 minutes, and then naturally cool after sintering. The mass ratio of soda to UHMWPE powder is 0.05:1;

[0020] (2) Put the sintered material into the dodecyl betaine solution with a mass fraction of 3% and completely soak it, and keep stirring the material. After soaking for 24 hours, take out and filter dry, and then bake at a constant temperature of 90 ° C for 24 hours , and seal the package after drying thoroughly.

[0021] When in use, open the airtight bag and put it into the fragrance card position and add the car fragrance to obtain the durable car sintered PE fragrance diffuser. It is measured that the volume of the durable vehicle-mounted si...

[0032] A durable vehicle-mounted sintered PE aromatherapy tablet is prepared by the following steps:

[0033] (1) Add baking soda to the 80-mesh ultra-high molecular weight polyethylene powder obtained by sieving, stir well and preheat the mold at 120°C for 100min in the first stage, and then turn to 150°C for sintering for 100min. The mass ratio of soda to UHMWPE powder is 0.01:1;

[0034] (2) Put the sintered material into a dodecyl betaine solution with a mass fraction of 1% and completely soak it, and keep stirring the material. After soaking for 24 hours, take out and filter dry, and then bake at a constant temperature of 80 ° C for 36 hours. , and seal the package after drying thoroughly.

[0035] When in use, open the airtight bag and put it into the fragrance card position and add the car fragrance to obtain the durable car sintered PE fragrance diffuser. It is measured that the volume ratio of the durable vehicle-mounted sintered PE aroma diffuser is 50%, and the fr...

Embodiment 3

[0037] A durable vehicle-mounted sintered PE aromatherapy tablet is prepared by the following steps:

[0038] (1) Add baking soda to the 120-mesh ultra-high molecular weight polyethylene powder obtained by sieving, fully stir it evenly, preheat the mold at 150°C for 60min in the first stage, then turn it to 200°C for 50min sintering, and then cool down naturally. The mass ratio of soda to UHMWPE powder is 0.1:1;

[0039] (2) Put the sintered material into the dodecyl betaine solution with a mass fraction of 5% and completely soak it, and keep stirring the material. After soaking for 24 hours, take out and filter dry, and then bake at a constant temperature of 100 ° C for 12 hours. , and seal the package after drying thoroughly.

[0040] When in use, open the airtight bag and put it into the fragrance card position and add the car fragrance to obtain the durable car sintered PE fragrance diffuser. It is measured that the volume ratio of the durable vehicle-mounted sintered PE...

Abstract

The invention discloses a durable vehicle-mounted sintered PE aromatherapy sheet. A long-lasting vehicle-mounted sintered PE aromatherapy tablet is prepared by the following steps: (1) adding a pore-enlarging agent or a bulking agent to ultra-high molecular weight polyethylene powder, fully stirring it evenly, heating up in stages, sintering and molding, and then cooling naturally; (2) ) Put the sintered material into the dodecyl betaine solution and completely soak it, and keep stirring the material, take out and filter dry after soaking, and then absorb the sesame oil after drying to obtain a durable vehicle-mounted sintered PE aromatherapy tablet. The oil absorption capacity of the PE sintered aromatherapy sheet proposed by the invention can reach 30%-60% by volume, which greatly increases the adsorption capacity and the effect of locking the fragrance and delaying the fragrance caused by the porous structure, and the average fragrance retention time can reach 20-60 days.

Description

technical field [0001] The invention relates to the technical field of aromatherapy sheets, in particular to a durable vehicle-mounted sintered PE aromatherapy sheet. Background technique [0002] With the development of the automobile industry, more and more users begin to use car aromatherapy to purify the air in the car and remove the peculiar smell in the car. There are many kinds of aromatherapy tablets on the market. Most of the traditional aromatherapy tablets are low-adsorption materials such as PVA, sponge, gypsum, and PP fiber cotton. The amount of absorbing sesame oil accounts for about 5%-40% of the oil absorption according to the volume of the fragrance tablets. Due to the characteristics of the material itself, traditional aromatherapy tablets cannot be used twice or will cause adverse reactions of peculiar smell, and the effect will gradually deteriorate 1-5 days after opening, which brings a lot of inconvenience to users. It is urgent to propose a new aromat...
