Description

Description
Preparation Method of Basalt Fiber Paper
Technical Field
The invention relates to the technical field of pulping and papermaking, in particular to a preparation method of basalt fiber paper. The invention claims priority to Chinese invention patent No. 201910369140.9, filed on May 5, 2019.
Background Art
Basalt fiber is a continuous fiber made by melting basalt stones at 1450’C to 1500'C and then subjecting the molten basalt stones to high-speed drawing with a platinum-rhodium alloy drain bushing. The basalt fiber is a newly-presented novel inotganic green high-performance fiber material made by melting basalt stones composed of silicon dioxide, alumina, calcia, iron oxide, titanium dioxide and other oxides, and then rapidly drawing the molten basalt stones with a bushing. The basalt continuous fiber has good stability, as well as various excellent properties, such as electrical insulation, corrosion resistance, burning resistance, and high temperature resistance. In addition, a small amount of waste is produced from the production process of the basalt fiber, low pollution is caused to the environment, discarded products can be transferred directly into eco-environment with no hazards posed. Therefore, the basalt fiber is an authentic green material. The basalt continuous fiber has been widely applied in various aspects including fiber-reinforced composites, friction materials, shipbuilding materials, insulation materials, automobile industry, high-temperature filter fabrics, and protection field.
At present, the basalt fiber composites are mainly applied on the basis of fabric structures. There are also techniques to prepare fiber paper by blending the basalt fiber with other fibers, e.g. Chinese invention patent publication No. 1948615, where a fiber paper is prepared from basalt fiber, aramid fiber and polyphenylene sulfide fiber by a wet process. The synthetic fiber paper has good mechanical properties, good resistance to high temperature, excellent tolerance to acids and bases, outstanding ultraviolet resistance, low hygroscopicity and better environmental resistance, i
2020100083 16 Jan 2020 and also features good insulating performance, high temperature filtering performance, radiation resistance, superior wave permeability and the like.
However, on one hand, the surface of basalt is well hydrophobic and has less water affinity than ordinary inorganic fibers, and therefore, dispersing is difficult for the basalt fiber. On the other 5 hand, the basalt fiber has a low content of surface active groups, a hydrogen bond and other bonds can hardly occur between the fibers, the finished paper has low strength and can hardly take shape. For the reasons listed above, related techniques of preparing thin paper-based materials solely with the basalt fiber have not been reported yet, and the applicable field and precision for the basalt fiber are thus limited.
Summary
In order to overcome the defects in the prior art, one object of the invention is to provide a preparation method of basalt fiber paper that can overcome the defects of basalt fiber such as low possibility of uniform dispersion and poor paper-forming strength, and thus produce the basalt 15 fiber paper having high uniformity and strength.
Another object of the invention is to provide basalt fiber paper obtained through the above-mentioned preparation method.
The third object of the invention is to provide application of the above-mentioned basalt fiber paper in temperature-resistant flame-retardant materials.
To achieve the above objects, the technical solution of the invention is provided as below.
Λ preparation method of basalt fiber paper comprises: performing alkali treatment on a pulp of a basalt fiber with an alkali treating agent to obtain an alkali-treated basalt fiber, performing acid treatment on a pulp of the alkali-treated basalt fiber with an acid treating agent to obtain an alkaliand acid-treated basalt fiber, adding a dispersing agent into a pulp of the alkali- and acid-treated 25 basalt fiber to allow for uniform dispersion, adding a mixture of an organic adhesive and an inorganic adhesive to allow for uniform dispersion, diluting, forming with inclined wires, and drying to obtain the basalt fiber paper.
According to the invention, the basalt fiber is imparted improved dispersibility after subjected to acid and alkali pretreatments, the strength of the basalt fiber under different service conditions is 30 also enhanced through adhesion of the organic adhesive and the inorganic adhesive, and the basalt
2020100083 16 Jan 2020 fiber paper having high uniformity and strength is prepared accordingly.
Preferably, the alkali treating agent is added in an amount of 2-4% by mass of the basalt fiber. The alkali treating agent is sodium hydroxide . Better results are obtained with the use of the sodium hydroxide.
