吸水树脂(Super absorbent Polymer，SAP)是一种新型功能高分子材料。它具有吸收比自身重几百到几千倍水的高吸水功能，并且保水性能优良，一旦吸水膨胀成为水凝胶时，即使加压也很难把水分离出来。高吸水性树脂是一种带有大量亲水基团的功能性高分子材料。以其高吸液能力、高吸液速度和高保液能力，广泛应用于生理卫生用品，如妇女卫生巾、纸尿裤、成人多功能护理垫、吸水纸、宠物垫等。使得此类产品大大轻度化、小型化、舒适化，给人们带来了福音，是卫生用品领域不可替代的理想产品。
Super absorbent Polymer (SAP) is a new type of functional polymer material.

直到80年代，吸水材料还是纤维素或基于纤维的产品，主要包括棉纸，棉花，海绵和绒毛浆。这些材料的保水率最多就是自重的20倍。
Until 80s, the absorbent material or cellulose or based on fiber products, including cotton, cotton, sponge and fluff pulp. The maximum water retention rate of these materials is 20 times the weight of self weight.
60年代早期，美国农业部进行改善土壤保水率的材料的研究。他们开发了基于聚合物嫁接到淀粉分子主链上的树脂。淀粉丙烯腈共聚物水解产品能够吸收自重400多倍的水。并且，这种胶不会像纤维基吸收材料那样释放水。
In the early 60s, the United States Department of agriculture conducted research on materials to improve soil water conservation. They developed resin based on polymer grafting to the main chain of starch molecules. The hydrolysate of the starch acrylonitrile copolymer can absorb more than 400 times the weight of water. And the glue does not release water as a fiber based absorption material.
这种高分子被称为“超级吸湿材料”。美国农业部将这种技术的内情转给一些美国公司，来寻求这一基本技术的进一步发展。尝试了大范围的组合，包括丙烯酸，丙酰胺和聚乙烯醇（PVA）。 "
This polymer is called "super absorbent material". The United States Department of agriculture has transferred this technology to some American companies to seek further development of this basic technology. A wide range of combinations, including acrylic acid, propanamide and polyvinyl alcohol (PVA), was tried. "
丙烯腈/丙酰胺共聚物曾被设计用来含高电解质/矿物质的条件下，并且在大量干/湿循环下的长期稳定性。主要用于农业和园艺业。和高强度的丙酰胺单体可以用做医用泄漏控制剂，电线电缆的防水。
Acrylonitrile / propanamide copolymers have been designed to contain high electrolyte / mineral conditions and have long term stability under a large number of dry / wet cycles. It is mainly used in agriculture and horticulture. And high - strength propylene amide monomer can be used as a medical leakage control agent, wire and cable waterproof.
吸水树脂 - 吸水树脂应用领域
Application field of absorbent resin water absorbent resin
1、在农业与园艺方面的应用
1. Application in agriculture and Horticulture
用于农业与园艺方面的高吸水性树脂又称为保水剂和土壤改良剂。我国是世界上缺水较严重的国家，因此，保水剂的应用就显得越来越重要，目前国内已有十几家科研院所的研制高吸水性树脂产品用于粮、棉、油、糖、烟、果、菜、林等60多种植物上进行应用试验，推广面积超过7万多公顷，并在西北、内蒙等地利用高吸水性树脂进行大面积防砂绿化造林。用于这方面的高吸水性树脂主要是淀粉接枝丙烯酸盐聚合交联物和丙烯酰胺-丙烯酸盐共聚交联物，其中盐已由钠型转向钾型。使用的方法主要有拌种、喷撤、穴施、或用水调成糊状后浸泡植物根部。同时，还可以利用高吸水性树脂对化肥进行包衣后施肥，充分发挥化肥的利用率，防止浪费和污染。国外还利用高吸水性树脂作为水果、蔬菜、食品保鲜包装材料。得米化工占地面积30000多平方米，专业从事吸水材料（SAP）的研发和生产，国内首家从事高吸水性树脂的高新技术企业。
Water absorbent resins used in agriculture and horticulture are also known as water retention agents and soil modifiers. China is the world of serious water shortage, therefore, SAP application becomes more and more important, currently has more than a dozen research institutes of the development of high water absorbent resin products used for test of grain and cotton, oil, sugar, tobacco, fruit, vegetables, forest and other 60 kinds of plants, promotion area of over more than 70 thousand hectares, and a large area of sand afforestation by using high water absorbent resin in the northwest, Inner Mongolia and other places. The super absorbent resin used for this aspect is mainly starch graft acrylic acid polymerization cross-linking material and acrylamide acrylic acid copolymer cross-linking material, and salt has changed from sodium type to potassium type. The use of methods mainly include dressing, spraying, fertilizing, or water into a paste soaking root. At the same time, the high water absorption resin can be used to fertilize the chemical fertilizer, make full use of the utilization rate of chemical fertilizer, prevent waste and pollution. The high water absorption resin is also used as the packaging material for fruit, vegetable and food. Demi chemical industry covers an area of more than 30000 square meters. It specializes in research and production of SAP, and is the first high-tech enterprise in China to engage in super absorbent polymers.
2、在医用、卫生方面的应用
2. Application in medical and health
主要用作卫生巾、婴儿尿布、餐巾、医用冰袋；用于调节环境气氛的胶状日用芳香材料。用作软膏、霜剂、擦剂、巴布剂等的基质医用材料，具有保湿、增稠、皮肤浸润、胶凝的作用。还可以制作成控制药物释放量、释放时间、释放空间的智能载体。
It is mainly used as sanitary napkins, baby diapers, napkins, medical ice bags, colloidal daily aromatic materials used to regulate environmental atmosphere. As a cream, ointment, liniment, Babu agent of the matrix materials, with moisturizing, thickening, skin infiltration, gel effect. It can also be made into an intelligent carrier to control the amount of drug release, release time, and release space.
高分子吸水树脂(简称SAP)是一种典型的功能高分子材料。SAP形似小珠子，直径只有约0.2mm，能吸收其自身重量数百倍、甚至上千倍的水，并具有很强的保水能力，所以它又被称为超强吸水剂或高保水剂。
Polymer absorbent resin (SAP) is a typical functional polymer material. SAP is like a small bead, only about 0.2mm in diameter. It can absorb hundreds of times its own weight and even thousands of times of water, and has strong water holding capacity. So it is also called super absorbent polymer or high water retaining agent.
SAP之所以有超强的吸水能力，是因为高吸水性树脂是具有许多亲水基团的低交联度或部分结晶的高分子聚合物。SAP粒径为100~120mesh(即0.212mm~0.254mm)时，吸收能力最佳;PH值6~8时，吸收速率最大。
The reason why SAP has super water absorbability is that high water absorption resin is a low degree of crosslinking or partially crystalline polymer with many hydrophilic groups. When the particle size of SAP is 100~120mesh (0.212mm~0.254mm), the absorption capacity is the best, and the absorption rate is the largest when the pH value is 6~8.
纸尿裤的吸收层的SAP是均匀地与绒毛纤维混合在一起的，SAP与绒毛纤维的均匀混合能够使吸液均匀，也避免了产生凝胶粘连和硬点扎穿纸幅表层，并且防止层间产生滑动。
The SAP of the absorbent layer of the diaper is evenly mixed with the wool fiber. The uniform mixing of SAP and wool fibers can make the liquid absorption even, and avoid gel sticking and hard spots piercing the surface of the paper, and prevent slippage between layers.
3、在工业方面的应用
