Embodiment 1

[0018] A long-lasting 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 then preheat the mold at 135°C for 80 minutes in the first stage, then sinter at 175°C for 75 minutes, and then cool naturally. The mass ratio of soda and 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 stir the material continuously, take it out after soaking for 24 hours, filter and dry it, and then bake it at a constant temperature of 90°C for 24 hours , airtight package after drying thoroughly.

[0021] When in use, open the sealed bag and put it into the fragrance card position and add car perfume to obtain a long-lasting vehicle-mounted sintered PE aromatherapy tablet. It is measured that the long-lasting vehicle-mounted sintered PE ar...

Embodiment 2

[0032] A long-lasting 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 then preheat the mold at 120°C for 100 minutes in the first stage, then sinter at 150°C for 100 minutes, and then cool naturally. The mass ratio of soda to UHMWPE powder is 0.01:1;

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

[0035] When in use, open the sealed bag and put it into the fragrance card position and add car perfume to obtain a long-lasting vehicle-mounted sintered PE aromatherapy tablet. It is measured that the long-lasting vehicle-mounted sintered PE aro...

Embodiment 3

[0037] A long-lasting 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, stir well, and then preheat the mold at 150°C for 60 minutes in the first stage, and then sinter at 200°C for 50 minutes. After sintering and forming, cool 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 stir the material continuously, take it out after soaking for 24 hours, filter and dry it, and then bake it at a constant temperature of 100°C for 12 hours , airtight package after drying thoroughly.

[0040] When in use, open the sealed bag and put it into the fragrance card position and add car perfume to obtain a long-lasting vehicle-mounted sintered PE aromatherapy tablet. It is measured that the long-lasting vehicle...

Abstract

The invention discloses a durable vehicle-mounted sintered PE aromatherapy sheet. The durable vehicle-mounted sintered PE aromatherapy sheet is prepared by the following steps: (1) adding a pore-enlarging agent or a swelling agent into ultra-high molecular weight polyethylene powder, fully and uniformly stirring, carrying out segmented heating, sintering and molding, and naturally cooling; and (2) completely soaking the sintered and molded material in a dodecyl betaine solution, continuously stirring the material, taking out the soaked material, draining, drying, and adsorbing sesame oil to obtain the lasting vehicle-mounted sintered PE aromatherapy sheet. The oil absorption amount of the PE sintered aromatherapy piece can reach 30%-60% of the volume ratio, the adsorption amount and the fragrance locking and delaying effect generated by the porous structure are greatly increased, and the average fragrance lasting time can reach 20-60 days.

Description

technical field [0001] The invention relates to the technical field of aromatherapy tablets, in particular to a durable vehicle-mounted sintered PE aromatherapy tablet. Background technique [0002] With the development of the automobile industry, more and more users have begun to use car aromatherapy to purify the air in the car and remove the peculiar smell in the car. There are many types of aromatherapy tablets on the market. Traditional aromatherapy tablets are mostly made of low-adsorption materials such as PVA, sponge, gypsum, and PP fiber cotton. The amount of absorbed sesame oil depends on the volume of the fragrance sheet. Due to the characteristics of the material itself, traditional aromatherapy tablets cannot be used twice or will cause adverse reactions of peculiar smell when used again, and the effect will gradually deteriorate within 1-5 days after opening, which brings a lot of inconvenience to users. It is urgent to propose new aromatherapy tablets to solv...
