Embodiment Construction

[0013] A polymer attapulgite composite gel, made of the following raw materials by weight (kg): acrylic acid 24, acrylamide 10, sodium alginate 8, guar gum 5, hydroxypropyl cellulose 4, ammonium persulfate 3. Calcium carbonate 4, sodium hydroxide 9, soybean protein powder 10, konjac glucomannan 7, β-cyclodextrin 5, Tween 80 0.6, modified attapulgite 8, appropriate amount of potassium dihydrogen phosphate, water Appropriate amount.

[0014] The preparation method of the modified attapulgite is as follows: a. Put the attapulgite raw ore into a hydrochloric acid solution with a concentration of 2mol / L, heat it in a water bath to 70°C, stir at 800r / min for 1.5h, filter, and filter the residue with deionized Wash with water to neutrality, dry, pulverize, pass through a 150 mesh sieve, and stand-by; % sodium hexametaphosphate, 1.5% polyvinyl alcohol, 0.8% sodium lauryl sulfate, 0.6% sodium polyacrylate, heated in a water bath to 80°C, disperse at high speed for 30min, centrifuge, a...

Abstract

The invention discloses polymer attapulgite plural gel and a preparation method thereof. The polymer attapulgite plural gel is prepared from the following raw materials in parts by weight: 20-25 parts of crylic acid, 8-12 parts of acrylamide, 5-10 parts of sodium alga acid, 4-6 parts of guar gum, 3-5 parts of hydroxy propyl cellulose, 2-4 parts of ammonium persulfate, 3-5 parts of calcium carbonate, 8-10 parts of sodium hydroxide, 10-15 parts of soyabean protein powder, 5-10 parts of konjac glucomannan, 4-6 parts of beta-cyclodextrine, 0.5-1 part of Tween 80, 5-10 parts of modified attapulgite, the proper amount of monopotassium phosphate and the proper amount of water. The polymer attapulgite plural gel plays a synergetic effect by the compositing of a plurality of polymer water-soluble matters and the modified attapulgite, and is significant in thickening effect, strong in adsorbability, good in water-retaining property, good in dispersibility, wide in application range, and applicable to the fields such as foods, pesticides, water treatment, textile printing, and coatings, can effectively keep the stability of a system, also has certain antibacterial activity and mildew resistance, and simultaneously can be widely applied under extreme conditions such as high temperature, meta-acid environments and alkali environments.

Description

technical field [0001] The invention relates to a polymer attapulgite composite gel and a preparation method thereof, belonging to the field of food thickeners. Background technique [0002] Polymer hydrogel is a gel with water as the dispersion medium. A part of hydrophobic groups and hydrophilic residues are introduced into the water-soluble polymers with network crosslinked structure. The hydrophilic residues combine with water molecules, and the water molecules A cross-linked polymer in which the hydrophobic residues swell when exposed to water, and are connected within the network. All water-soluble or hydrophilic polymers can form hydrogels through certain chemical cross-linking or physical cross-linking. These polymers can be divided into two categories according to their sources, natural and synthetic. Natural hydrophilic polymers include polysaccharides (starch, cellulose, alginic acid, hyaluronic acid, shell hydrogel, etc.) and polypeptides (collagen, poly-L-lysi...
