[0031] The preparation method of described superabsorbent resin, comprises the following steps:

[0032] S1. Mix methacrylate, inorganic alkali solution, acrylamide, 2-methylbenzenesulfonic acid, baking soda and ammonia water evenly, stir at 4000-6000r / min for 10-15min, then add xanthan gum and mix evenly. Heat up to 80-90°C, keep warm for 1-2h, stir at 650-850r / min for 1-2h, cool to room temperature to obtain the base material;

[0033] S2. After mixing polylactic acid, chitosan and silane coupling agent KH-570, heat up to 50-60°C, keep warm for 1-3h, keep stirring during the heat preservation process, and then add antibacterial modification additives and heat-resistant Mix the modified additives evenly, continue to heat up to 70-80°C, stir and disperse at 300-350r / min for 5-15min to obtain modified fillers;

[0034] S3. In a closed mixer, mix the base material and the modified filler evenly, heat up to 80-90°C, keep warm for 1-3h, then stir at 1500-2500r / min for 1-2h, cool ...

Abstract

The invention discloses super absorbent resin and a preparation method thereof. The super absorbent resin comprises the following raw materials: metacrylic acid ester, an inorganic alkali solution, acrylamide, 2-methylbenzenesulfonic acid, xanthan gum, sodium bicarbonate, ammonia water, polylactic acid, chitosan, an antibacterial modified aid, a heat-resistant modified aid and a silane coupling agent KH-570; and the super absorbent resin is prepared by steps, such as preparing base materials and modified fillers and then mixing the base materials and the modified fillers. The super absorbent resin has excellent antibacterial and heat-resistant properties.

Description

【Technical field】 [0001] The invention belongs to the technical field of resin preparation, and in particular relates to a superabsorbent resin and a preparation method thereof. 【Background technique】 [0002] Superabsorbent resin is a new type of functional polymer material developed in the past 30 years. It has a low degree of crosslinking or partially crystalline polymer with many hydrophilic groups. Therefore, it has the characteristics of general polymer compounds and has excellent Excellent water absorption and water retention properties, it can absorb water up to hundreds to thousands of times its own weight, and form a gel after absorbing water and swelling. At the same time, it has the advantages of functional polymer materials and can be used in agriculture, forestry, horticulture, medicine, medical treatment, physiological hygiene, petroleum, chemical industry, building materials, environmental protection, food, artificial intelligence materials, sensitive materia...
