とする。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention is intended for use in plant fibers that are inherently flammable (pulp, cotton fibers, e.g.
tc. ), which has been rendered flame-retardant through skillful chemical treatment, and a manufacturing method that enables industrial mass production of such plant fiber materials, including asbestos, rock wool, and glass wool. As a technology to provide a new construction filler to replace such materials, as a technology to provide flame-retardant vegetable fiber boards and flame-retardant vegetable fiber chipboards, and as a technology to provide a variety of heat-insulating and sound-absorbing materials made of flame-retardant vegetable fibers. It can be widely used as a technology to provide new flame-retardant materials, and a technology to provide new materials for brake linings. [Conventional technology and technical issues to be solved] As is well known, asbestos and rock wool are widely used in various construction fields because they are fiber materials that exhibit excellent properties of nonflammability, heat resistance, heat insulation, and sound insulation. It is also widely used as a material for flame-retardant and fire-resistant paper and brake linings for automobiles, etc. However, recently it has been pointed out that there is a risk of lung cancer when inhaling airborne asbestos fibers and rock wool fibers into the lungs, and there is an urgent need for safer textile materials to replace them. ．． However, although it can be said that mineral fibers other than asbestos and rock wool are generally excellent in nonflammability and heat resistance, when considering the lightness, heat insulation, and soundproofing properties required in the construction field, It is not necessarily sufficient as a raw material for flame-retardant and fire-resistant paper, and has drawbacks in terms of feel, breathability, and lightness.On the other hand, it is difficult to use it as a brake lining material for automobiles in terms of its coefficient of friction. However, it is no exaggeration to say that there is no mineral fiber that has sufficient physical properties to replace asbestos, and if safety is required, there is no such thing. be. The present invention seeks to find a fiber material in plant fibers that can replace asbestos and rock wool, and has a high durability in which an insoluble, nonflammable inorganic compound is immovably fixed in the voids of the plant fibers. The technical problem is to provide a flame-retardant vegetable fiber material.

を用いる。That is, the present invention employs a method of bringing plant fibers whose voids are swollen with a phosphate aqueous solution into contact with a weak alkaline atmosphere, thereby converting the phosphate component, which is water-soluble and easily washed away, into an insoluble, nonflammable component. The main purpose is to obtain a flame-retardant vegetable fiber material by solidifying and fixing it in the voids of fibers as a phosphate. Therefore, the following notes are added regarding the specific contents of the means adopted in the present invention. First, plant fiber materials to which the present invention can be applied include wood (softwood and hardwood), straw, and espart.

utbery, linter, etc., or those that are further chemically processed and refined into chemical pulp or semi-chemical pulp, and furthermore, products obtained by loosening waste paper and paper waste. This applies to almost all plant fibers, including recycled pulp. Incidentally, the voids in these plant fibers reach a ratio of several tens of pores to the fiber cell tissue, and this ratio is even larger in chemical valves from which lignin has been removed. Next, the phosphate used in the present invention needs to be water-soluble because it needs to be prepared as an aqueous solution and infiltrated into the voids of the plant fibers, and it is necessary to make it water-soluble, such as barium phosphate, calcium phosphate, magnesium phosphate, etc. Use.

なく、防火上も非常に役立つ。In addition, in the method of the present invention, when the plant fiber containing the phosphate solution in a swollen state is treated with an alkali, (
# L) J P O. (Ammonium phosphorus) is dissolved in water to prepare an aqueous solution with a weak alkaline (pif 9 ) level, and the solution is immersed in the solution or brought into contact with ammonia gas or the like. [Example] The present invention will be described below with reference to Examples. A saturated aqueous solution of lJuLΩ fj (1 (HzPOa)
℃ and swollen to water-saturated pulp (mechanical pulp made by crushing deciduous pine) is immersed in the pulp for 5 to 30 minutes, then taken out and the impregnated liquid is squeezed out as appropriate, and then, Secondary phosphorous acid: (NH4)OHPO. Dip in a weak alkaline aqueous solution (pH 9) of
It was subjected to water washing and drying treatment. As a result, the pulp was 50% per 100% absolute dry weight.
The flame-retardant mechanical pulp contained a non-combustible and insoluble inorganic compound with a weight increase of ~90%. The pulp thus obtained was deposited and compression molded to form a ceiling board (12 am thick, 3 x 3
00mrI+X 300mra) and convert it to rJ
When the material was subjected to base material tests, surface tests, and additional tests in accordance with Is Standard A 1321 "Flame Retardant Test Methods for Building Interior Materials and Construction Methods," the results were equivalent to class 2 flame retardant in all tests. was gotten. From this fact, it can be seen that the deciduous pine mechanical pulp used in this example has been modified to be highly flame retardant and fire resistant. 11
Meng Calcium Phosphate Ca3CPOa>t and Phosphate HIP
O. A mixed saturated aqueous solution of 40-60%
Cotton fibers heated to 'C and swollen to water saturation were immersed in it for 10 to 30 minutes, then brought into contact with ammonia gas, and then subjected to drying treatment. 1
The weight increased by 90% compared to 00, and 90% of the weight was nonflammable components. A lit cigarette was placed on top of the cotton fibers obtained in this way until it burned out, but the cotton fibers did not change much overall except for some discoloration in the areas that were in direct contact with the cigarette flame. It exhibited excellent flame retardancy. The main cause of the discoloration is thought to be the carbonized tar component of the cigarette itself.
C. Effects of the present invention] As explained above using the examples, the method of the present invention can achieve flame retardancy by simply applying a process of expanding a phosphate solution into the voids of plant fibers and applying alkali treatment. This makes it possible to very efficiently produce plant fiber materials that are rich in strength and heat resistance, and the resulting flame-retardant plant fibers are somewhat heavier than normal plant fibers. It is much lighter than mineral fibers, and has the feel and breathability (breathability) unique to plant fibers, as well as bulkiness, restoring elasticity, and friction properties. ．． Therefore, if the plant fiber material obtained according to the present invention is used as a heat insulating material or a sound insulating material for heat insulating walls or sound proof walls of buildings, not only high quality heat insulating walls or sound proof walls can be obtained, but also fire prevention is achieved. very helpful.
