Embodiment Construction

[0016] Below in conjunction with embodiment further illustrate the present invention.

[0017] The preparation method of inorganic mineral fiber modifier comprises the following steps:

[0018] (1) Add 7 parts by weight of basic aluminum chloride and 10 parts of water in a flask with a reflux device, fully stir until the aluminum chloride is completely dissolved, add 15 parts of methanol, and heat to reflux;

[0019] (2) Add 1 part of 1,2-propanediol, react under reflux for 60 minutes, extract methanol under reduced pressure, and dry the residue in an oven at 120°C for later use;

[0020] (3) Weigh 1 part of zirconium oxychloride, 4.5 parts of dodecyl dimethyl betaine and 10 parts of 1,2-propylene glycol by weight, and react in a water bath at 80° C. for 30 minutes;

[0021] (4) Add 1.5 parts of the product obtained in step (2), react for 50 minutes, and extract the solvent under reduced pressure to obtain the target product.

Abstract

The invention provides an inorganic mineral fiber modifying agent, which is characterized in that the chemical structure formula is as follow: [A1(OR1O)ac1b(OH)c]x[O C(R2)O]y[ZrCld(OH)e]z. In the formula, x, y, and z are equal to 1 to 100; 2a plus b plus c is equal to 4; d plus e is equal to z; -OR1O- is an organic dentate with homonymous energy cluster; -OR2O- is a dentate with positive ion radical. The invention can improve the plasticity of the mineral; improve the viscosity coefficient of the suspending liquid of the mineral fiber in water; and change the surface electric charge performance of the mineral fiber. The inorganic coupling radical is the molecule structure can be reacted with various function clusters on the surface of the mineral fiber so as to form strong and powerful chemical bonding; the other part of organic radical with positive ion capability can be chemically reacted with the plant organic fiber radical with negative electric charge so as to strengthen the combination force between the mineral fiber and the plant fiber, providing powerful guarantee for largely utilizing the inorganic mineral fiber in wet paper making.

Description

technical field [0001] The invention relates to a modifier and a preparation method thereof, in particular to a modifier for inorganic mineral fibers used in papermaking. Background technique [0002] Inorganic mineral fiber is a new material for active papermaking prepared by using modern technology to prepare white fibrous ore produced naturally through fiberization, superfine grinding, and surface composite modification, such as basalt fiber, wollastonite fiber, and fly ash fiber. , glass fiber, etc. Inorganic mineral fiber is different from plant fiber, the preparation process will not cause environmental pollution, and it is also different from traditional fillers such as calcium carbonate and talcum powder. It is a new type of papermaking material between short plant fibers and traditional fillers. Inorganic mineral fibers are used in the paper industry, which can save a lot of plant fibers, which is of great significance to reduce the cost of papermaking, protect for...
