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
The present invention relates to a kind of modifier and preparation method thereof, specifically, relate to a kind of modifier of paper grade (stock) inorganic mineral fiber.
Background technology
Inorganic mineral fiber is to adopt modern technologies, with the white fiber shape ore of natural output through the fibration ultra-fine grinding, surface recombination modified after the active paper grade (stock) new material of preparation, such as basalt fibre, wollastonite fibre, coal ash fiber, glass fibre etc.Inorganic mineral fiber is different from string, and preparation process can not cause environmental pollution, also is different from conventional filler---and calcium carbonate, talcum powder, it is a kind of novel papermaking material between short fiber of plant and conventional filler.Inorganic mineral fiber is used for paper industry, can save a large amount of strings, and this conserves forests and ecological environment to reducing the papermaking cost, and reducing paper-making pollution has important meaning.But inorganic mineral fiber fragility is big, rigidity strong, the surface polarity group is few, combines difficulty with organic fiber, uses paper strength will be descended significantly.How to improve the surface nature of inorganic mineral fiber, strengthen the adhesion of inorganic mineral fiber and string, thereby the consumption of increase mineral fibres becomes the focus of present research.
Summary of the invention
Technical problem to be solved by this invention provides a kind of easily synthetic, cost is low and modified effect is good inorfil modifier, can strengthen the adhesion between inorganic mineral fiber and other material, provide strong assurance for inorganic mineral fiber is used for wet papermaking in a large number.
Technical scheme of the present invention is as follows:
A kind of inorganic mineral fiber modifier is characterized in that its chemical structural formula is as follows:
