Embodiment 1
[0023] First, use SEBS, PP and white mineral oil, mix according to the mass ratio of 30:21:49, add to the twin-screw extruder for granulation, the screw L / D of the twin-screw extruder is 21 / 1, and the processing temperature at 235°C to obtain TPE particles.
[0024] Then, 45g of the TPE particles obtained in the above steps, 75g of EVA particles, 65g of woody incense raw material and 15g of benzyl benzoate were added to a closed mixing tank and mixed for 15 minutes, and then adsorbed at room temperature for 12 hours to obtain a dry thermoplastic temperature-resistant fragrance. Masterbatch.
[0025] Finally, a ring-shaped mold is installed in the injection molding machine, and the fragrance masterbatch obtained above is added to the injection molding machine, and injected at a pressure of 45MP, a temperature of 135°C, and a processing time of 120s to obtain a vehicle-mounted temperature-resistant elastic fragrance release product. The fragrance content of this product is 40%,...
Embodiment 2
[0027] First, use EVA, SEBS, PP and white mineral oil, mix according to the mass ratio of 12:41:31:37, add to the twin-screw extruder for granulation, the screw L / D of the twin-screw extruder is 21 / 1. The processing temperature is 235°C to obtain TPE particles.
[0028] Then, add 100g of TPE particles obtained in the above steps, 50g of EVA particles and 65g of citrus essential oil into a closed mixing tank and mix for 15 minutes, then absorb at room temperature for 12 hours to obtain a thermoplastic temperature-resistant fragrance masterbatch with a dry surface.
[0029] Finally, install a cuboid-shaped mold on the injection molding machine, add the fragrance masterbatch obtained above into the injection molding machine, and perform injection molding at a pressure of 42MP, a temperature of 145°C, and a processing time of 120s to obtain a vehicle-mounted temperature-resistant elastic fragrance release product. The fragrance content of this product is 25%, the temperature resi...

Abstract
The invention discloses a vehicle-mounted temperature-resistant elastic fragrance-releasing product and a preparation method thereof, and belongs to the technical field of functional master batch preparation. The vehicle-mounted temperature-resistant elastic fragrance-releasing product solves the problems that an existing vehicle interior perfuming technology depends on liquid essence, essence overflows, pollutes surrounding objects, is inflammable and is not suitable for being applied to the environment with strict requirements for temperature. According to the invention, the TPE and EVA elastomer plastic particles with simple components are selected to be mixed with perfume and a stabilizer to prepare a perfume-holding solid which has the perfume absorption amount of 25-50% and is formed into various shapes through injection molding/hot pressing and other processes, the surface of the solid is dry and comfortable, and the shape of the solid is kept unchanged at the temperature of -20 DEG C to 110 DEG C (the conventional temperature of the vehicle-mounted solid perfume is required to be 0-90 DEG C); and the solid continuously releases fragrance outwards for 180 days or more (under the condition that the fragrance type can be identified when the fragrance intensity is greater than or equal to 2), and the temperature-resistant elastic fragrance release product is suitable for being used in the vehicle body.
Description
technical field [0001] The invention relates to a vehicle-mounted temperature-resistant elastic fragrance-releasing product and a preparation method thereof, belonging to the technical field of preparation of functional masterbatches. Background technique [0002] Fragrance not only has the effect of covering peculiar smell, but also has the effect of beautifying the environment. Products with fragrance releasing function in daily life have become personalized commodities that people demand. The existing perfuming technology relies on liquid essence, which has problems such as overflow of essence, contamination of surrounding objects, flammability, etc., and is not suitable for application in cars with large temperature changes. Moreover, the existing fragrance carriers are mainly environmentally friendly plastics. Conventional plastics have a relatively low fragrance absorption capacity, and as the fragrance absorption increases, the physical properties of the plastic carri...
