Problems solved by technology

[0002] After searching the patent literature, it is known that the composition of absorbing ammonium, potassium, calcium, magnesium and other nutrients with polyacrylic acid resin has been reported. It is used in agriculture and afforestation, but the main function is to maintain water and soil and resist leaching, and to increase fertilizer by absorbing water and retaining water. , cross-linked with small molecular compounds as plant growth regulators, it has not been reported that it can improve soil structure, absorb heavy metals and pesticide residues, improve the quality of agricultural products, especially the safety quality, and cannot meet the needs of safe agricultural product production

example 1

[0011] Example 1 Take 10kg of acrylic acid, 20kg of 20-45% sodium hydroxide, add 40kg of water to neutralize the heat of polymerization, adjust the pH of the aqueous solution to PH7-14, add free radical initiator potassium persulfate or ammonium persulfate at 0.1-0.6g per liter of acrylic acid , put the aqueous solution to polymerize and cool to room temperature to obtain the aqueous sol of sodium polyacrylate or ammonium salt, which contains 4-10% of sodium or ammonium polyacrylate and 90-85% of water.

example 2

[0012] Example 2 Take 10kg of acrylic acid, 20kg of 20-29% ammonia water, add 20kg of water to neutralize the heat of polymerization, adjust the pH of the aqueous solution to PH7-14, add free radical initiator potassium persulfate or ammonium persulfate at 0.1-0.6g per liter of acrylic acid, and statically Place the aqueous solution to polymerize and cool to room temperature to obtain the aqueous sol of polyacrylic acid sodium or ammonium salt, which contains 4-10% of sodium or ammonium polyacrylate and 90-85% of water.

Abstract

The invention is an earth-adjusting agent keeping water, earth and fertilizer and controlling pollution and the making technique. It uses 20-45% NaOH 1-2 shares or 20-29% ammonia 4-2 shares and 95-98% acrylic acid 1 share, adds in water whose bulk is 2-15 times acrylic acid's to get rid of polymerization heat, the polymeric water solution pH 7-14, and adds the free evocating agent, potassium persulphate or ammonium persulphate to get the hydrosol of polyacrylate sodium or ammonium salt.

Description
