Embodiment 1

[0016] A preparation method for deodorant masterbatch, comprising the following steps:

[0017] Step 1, mix 10 parts by weight of PET, 5 parts of PP, 1 part of dimethyl methylphosphonate, 1 part of sodium carbonate and 0.5 part of sodium tripolyphosphate to obtain mixture 1, which is mixed uniformly and stirred The rotating speed is 180 rpm, and the mixing time is 20 minutes;

[0018] Step 2, put the mixture one in the reaction kettle, add 2 parts by weight of methyl tetrahydrophthalic anhydride, 1 part of butyl acrylate, 0.3 parts of sodium borohydride, and heat to Stir at 70°C for 20 minutes at a stirring speed of 60 rpm to obtain mixture 2;

[0019] Step 3, add 25 parts by weight of silica sol, 0.5 parts of barium stearate and 1 part of hypromellose to mixture 2, mix well, and extrude in a twin-screw extruder at a temperature of 180 -200°C to obtain a deodorant masterbatch.

Embodiment 2

[0021] A preparation method for deodorant masterbatch, comprising the following steps:

[0022] Step 1, mix 13 parts by weight of PET, 6 parts of PP, 2 parts of dimethyl methylphosphonate, 2 parts of sodium carbonate and 0.6 part of sodium tripolyphosphate to obtain mixture 1, which is uniformly mixed and stirred The rotating speed is 188 rpm, and the mixing time is 23 minutes;

[0023] Step 2, put the mixture one in the reaction kettle, add 3 parts by weight of methyl tetrahydrophthalic anhydride, 2 parts of butyl acrylate, 0.4 parts of sodium borohydride, and heat under the protection of argon to 75°C, stirring for 26 minutes at a stirring speed of 70 rpm to obtain mixture 2;

[0024] Step 3, add 3 parts by weight of silica sol, 0.6 parts of barium stearate and 2 parts of hypromellose to mixture 2, mix well, and extrude in a twin-screw extruder at a temperature of 180 -200°C to obtain a deodorant masterbatch.

Embodiment 3

[0026] A preparation method for deodorant masterbatch, comprising the following steps:

[0027] Step 1, mix 17 parts by weight of PET, 8 parts of PP, 2 parts of dimethyl methylphosphonate, 3 parts of sodium carbonate and 0.8 part of sodium tripolyphosphate to obtain mixture 1, which is mixed uniformly and stirred The rotating speed is 190 rpm, and the mixing time is 26 minutes;

[0028] Step 2, put the mixture one in the reaction kettle, add 3 parts by weight of methyl tetrahydrophthalic anhydride, 2 parts of butyl acrylate, 0.5 part of sodium borohydride, and heat to Stir at 78°C for 26 minutes at a stirring speed of 70 rpm to obtain mixture 2;

[0029] Step 3, add 4 parts by weight of silica sol, 0.8 parts of barium stearate and 2 parts of hypromellose to mixture 2, mix well, and extrude in a twin-screw extruder at a temperature of 180 -200°C to obtain a deodorant masterbatch.

Abstract

The invention discloses a method for preparing a deodorant master-batch. The method comprises the following steps: uniformly mixing PET, PP, dimethyl methylphosphonate, sodium carbonate and sodium tripolyphosphate to obtain a mixture I; then, putting the mixture I into a reaction kettle, adding tetrahydromethylphthalic anhydride, butyl acrylate and sodium borohydride, heating and stirring under the condition of inert gas protection to obtain a mixture II; and finally, adding silica sol, a lubricating agent and hydroxypropyl methylcellulose into the mixture II, uniformly mixing, and extruding in a twin-screw extruder to obtain the deodorant master-batch. The deodorant master-batch prepared by the method has an excellent deodorizing effect, and can be widely applied to the deodorization field.

Description

technical field [0001] The invention belongs to the technical field of chemical deodorant preparation, and in particular relates to a preparation method of a deodorant masterbatch. Background technique [0002] Polyethylene terephthalate, referred to as PET, is a high polymer, which is derived from the dehydration condensation reaction of ethylene terephthalate. Ethylene terephthalate is obtained from the esterification of terephthalic acid and ethylene glycol. PET is a milky white or light yellow, highly crystalline polymer with a smooth and shiny surface. It has excellent physical and mechanical properties in a wide temperature range. The long-term use temperature can reach 120 ° C. It has excellent electrical insulation. Even at high temperature and high frequency, its electrical properties are still good, but its corona resistance is poor. Creep resistance, fatigue resistance, friction resistance and dimensional stability are all very good. PET is widely used in vario...
