Embodiment 1

[0025] (1) Add deionized water dropwise to 35g carboxymethyl dextran sodium under stirring until it is completely dissolved, then use dilute nitric acid to adjust the pH value to 3-4, heat to 60-70°C and keep stirring, and check every 5 minutes Once the pH value exceeds 4, add dilute nitric acid to control the pH value at 3-4. When the pH value of the system continues to stabilize at 3-4 within 15 minutes, add 3g of N-methylolacrylamide and continue heating Keep stirring for 3 hours in the reflux state, then add 5g trimethylolpropane trimethacrylate and 0.05g potassium persulfate, keep stirring for 2 hours under reflux, and naturally cool the resulting mixture to below 50°C and send it to a spray dryer for drying The obtained granules are made into micropowder by ultrafine pulverizer to obtain the water-based dextran-acrylic resin complex;

[0026] (2) Mix 8g of cationic guar gum, 1g of food-grade γ-polyglutamic acid and 0.005g of tetrabutyl titanate, heat to a molten state an...

Embodiment 2

[0030] (1) Add deionized water dropwise to 30g carboxymethyl dextran sodium under stirring until completely dissolved, then use dilute nitric acid to adjust the pH value to 3-4, heat to 60-70°C and keep stirring, and check every 5 minutes Once the pH value exceeds 4, add dilute nitric acid to control the pH value at 3-4. When the pH value of the system continues to stabilize at 3-4 within 15 minutes, add 3g of N-methylolacrylamide and continue heating Keep stirring for 3 hours in the reflux state, then add 3g of trimethylolpropane trimethacrylate and 0.05g of potassium persulfate, and keep stirring for 2 hours under reflux again. When the resulting mixture is naturally cooled to below 50°C, it is sent to a spray dryer and dried. The obtained granules are made into micropowder by ultrafine pulverizer to obtain the water-based dextran-acrylic resin complex;

[0031] (2) Mix 10g of cationic guar gum, 2g of food-grade γ-polyglutamic acid and 0.005g of tetrabutyl titanate, heat to ...

Embodiment 3

[0035] (1) Add deionized water dropwise to 35g carboxymethyl dextran sodium under stirring until it is completely dissolved, then use dilute nitric acid to adjust the pH value to 3-4, heat to 60-70°C, keep stirring, and check every 5 minutes For one pH value, when the pH value exceeds 4, add dilute nitric acid to control the pH value at 3-4, and when the pH value of the system continues to stabilize at 3-4 within 15 minutes, add 3g of N-methylolacrylamide and continue heating Keep stirring for 3 hours in the reflux state, then add 5g of trimethylolpropane trimethacrylate and 0.05g of potassium persulfate, reflux and keep stirring for 2 hours, and the resulting mixture is naturally cooled to below 50°C and sent to a spray dryer for drying The obtained granules are made into micropowder by ultrafine pulverizer to obtain the water-based dextran-acrylic resin complex;

[0036](2) Mix 8g of cationic guar gum, 1g of food-grade γ-polyglutamic acid and 0.005g of tetrabutyl titanate, h...

Abstract

The invention discloses a long-acting gel-type in-car air refreshing agent, which relates to the technical field of refreshing agents. The long-acting gel-type in-car air refreshing agent is preparedfrom the following raw materials in parts by weight: 25 to 35 parts of carboxymethyl dextran sodium, 5 to 10 parts of cationic guar gum, 1 to 5 parts of trimethylolpropane trimethacrylate, 1 to 5 parts of cyclamen aldehyde, 1 to 5 parts of hydrogenated castor oil, 1 to 5 parts of polyaluminium sulfate, 0.5 to 3 parts of N-methylol acrylamide, 0.5 to 3 parts of gamma-polyglutamic acid, 0.5 to 3 parts of heliotropin, 0.5 to 3 parts of 4A molecular sieve activating powder, 0.01 to 0.05 part of potassium peroxodisulfate, and 0.005 to 0.01 part of tetrabutyl titanate. According to the long-acting gel-type in-car air refreshing agent, the self-made carrier is used for loading the spice cyclamen aldehyde and heliotropin so as to control the volatilizing speed of the spice and to play a role in sustaining the release of fragrance; and meanwhile, the prepared refreshing agent is kept at a gel state, and the slow release of the fragrance of the spice is kept, so that the in-car air quality is effectively improved.

Description

Technical field: [0001] The invention relates to the technical field of fresheners, in particular to a long-acting gel-type car interior air freshener. Background technique: [0002] Air freshener is a chemical product that has been used in the field of environmental sanitation since the 20th century. It purifies the air by covering up the peculiar smell in the air. At present, air fresheners sold on the market are mainly divided into liquid fresheners and solid fresheners. [0003] The liquid freshener sprays the air freshener into the air to cover up the peculiar smell in the air, but it is volatile in the air under high temperature, and accompanied by the oxidation of light, so that its effectiveness in the air is very short, and it needs to be cleaned by increasing the spraying frequency. To ensure the purpose of fresh air, this has caused troubles in use and requires the consumption of a large amount of fresheners. [0004] The most widely used solid fresheners are ge...
