Embodiment 1

[0040] Take materials according to the following ratio: 3% polyvinyl chloride (PVC) resin, 96.9% essence, 0% milky white oil and 0.1% butylated hydroxytoluene (BHT).

[0041] Fully mix 3% polyvinyl chloride resin with 96.9% essence to obtain material 1, without adding milky white oil, a transparent paste can be obtained; add 0.1% of butylated hydroxytoluene (BHT) to the material In one, stir until completely dissolved to obtain material two; stir and heat material two to 150°C until the polyvinyl chloride (PVC) resin is fully melted, then canned.

[0042] 20g of the finished product prepared from the above formula, at room temperature of 25°C, the strong fragrance can last for about 60 days depending on the type of fragrance. Compared with other products of the same weight, the fragrance is strong and the fragrance lasts for a long time.

Embodiment 2

[0044] The materials are taken in the following proportions: 10% polyvinyl chloride (PVC), 89.2% essence, 0.5% milky white oil and 0.3% butylated hydroxytoluene (BHT).

[0045] Fully mix 10% polyvinyl chloride resin and 89.2% essence to obtain material 1, then add 0.5% milky white oil to material 1, and mix well to obtain material 2; add 0.3% dibutyl Add hydroxytoluene (BHT) to material 2 and stir until completely dissolved to obtain material 3; stir and heat material 3 to 120-160°C until the polyvinyl chloride (PVC) resin is fully dissolved, then pack it in a can.

[0046] 30g of the finished product prepared by the above formula, at room temperature of 25°C, depending on the type of fragrance, the strong fragrance can last for about 90 days. Compared with other products of the same weight, the fragrance is strong and the fragrance lasts for a long time.

Embodiment 3

[0048] The materials are taken in the following proportions: 70% polyvinyl chloride (PVC) resin, 28% essence, 1% milky white oil and 1% butylated hydroxytoluene (BHT).

[0049] Fully mix 70% polyvinyl chloride resin and 28% essence to obtain material 1, then add 1% milky white oil to material 1, and mix well to obtain material 2; Add hydroxytoluene (BHT) into material 2 and stir until completely dissolved to obtain material 3; stir and heat material 3 to 150°C until the polyvinyl chloride (PVC) resin is fully melted, then pack it in a can.

[0050] 30g of the finished product prepared by the above formula, at room temperature of 25°C, depending on the type of fragrance, the strong fragrance can last for about 30 days. Compared with other products of the same weight, the fragrance is strong and the fragrance lasts for a long time.

Abstract

The invention relates to paste-like air fresheners, particularly to a paste-like air freshener with PVC (polyvinyl chloride) resin as a main gel raw material. According to the technical scheme, the air freshener comprises 2-70% of the PVC resin, 28-97.8% of essence, 0-1% of milky-white oil and 0.1-1% of BHT (butylated hydroxytoluene). A preparation method comprises the steps as follows: fully and evenly mixing 2-70% of the PVC resin with the 28-97.8% of essence to obtain a first material, adding the 0-1% of milky-white oil into the first material, and fully and evenly mixing the mixture to obtain a second material; adding the 0.1-1% of BHT into the second material, stirring the mixture until complete dissolution to obtain a third material; and stirring and heating the third material to the temperature of 120-160 DEG C until the PVC resin fully melts, and canning the mixture. The paste-like air freshener has the benefits as follows: the PVC resin is taken as the main gel raw material, no additional solvent is required to be used, the essence is directly used as a dissolution carrier, and the addition amount of the essence is up to 97.8%; the air freshener is strong in fragrance and long in fragrance duration; and the process is simple and convenient.

Description

technical field [0001] The invention relates to a paste-like air freshener, in particular to a paste-like air freshener with polyvinyl chloride (PVC) resin as the main gel material. As the amount of polyvinyl chloride (PVC) resin added increases, the paste-like air freshener increases in hardness, so that it becomes close to or directly solid. Background technique [0002] Existing pasty air freshener has following three kinds of defects: [0003] 1. Basically use water or some oily raw materials as the main solvent, the volume is relatively large, the weight of the paste is generally 50-200g, and the transportation cost is high; [0004] 2. Due to the limitations of raw materials and technology, the amount of essence added is small, generally 3%-7%, the fragrance is relatively light, and the duration of the fragrance is short. In summer, it usually lasts for 10-20 days; [0005] Three, due to the many raw materials used, the manufacturing process is complicated. [0006]...
