Problems solved by technology

In addition, since it is difficult to manufacture paper with a strength comparable to that of Japanese paper, especially when it is made into a concrete form, there is a problem that cannot be used due to insufficient strength.

no. 1 Embodiment

[0019] The 1st embodiment: this 1st embodiment is the concrete formwork, and the stem, stem, bark, core etc. of bamboo are pulverized into fragments, powder, and are copied into the slurry of powder slurry and paddle sheet, and get powder slurry, Add 3 kg of paddles to 5 kl of water and dissociate in a dissolving tank to become a suspension. Then, mix 5% of seaweed paste (relative to the weight ratio of the paddle) in the suspension, and after fully mixing, carry out papermaking with a dipping net of a set shape, and use 5kg / cm 2 Pressure extruding makes the concrete mold of the first embodiment. The paper weight of the concrete form base material is 0.1kg / m 2 .

no. 2 Embodiment

[0020] The 2nd embodiment: this 2nd embodiment is to make the plate-like processed product of paper shape with wall paste, partition fan paste etc. Add 2.1kg of slurry obtained from waste bamboo and 0.9kg of slurry obtained from coconut husk into 5kl of water and dissociate into mud in a dissolution tank to make a suspension. Then, mix 1% gelatin paste (relative to the weight ratio of the total pulp sheet) in the suspension, carry out papermaking after fully mixing, press and dry with hot rollers, and make thick 0.5mm, paper weight 0.1kg / cm 2 plate-shaped processed products. This embodiment fully has the effects of strength, anti-mildew, antibacterial effect, moisture regulating power, and no harmful gas generation as the plate-shaped processed product of the present invention. Adjust the feel or appearance of the material, so in addition to wall paste or partition paste. Of course, it can be widely used in curtains, other indoor surface materials, interior materials in cars...

no. 3 Embodiment

[0022] The 3rd embodiment: this 3rd embodiment is wall paste, partition fan pulp etc., but do not make the shape of wallpaper or partition paper but spread on the surface of the object to be mounted as muddy thick suspension and dry, It can be directly used as a mounting material for board-shaped walls or partitions in a slurry state. The weight per unit area depends on the thickness spread on the surface, but the thickness after drying is about 0.5mm. The feature of this third embodiment is that it not only has the same effect as the aforementioned second embodiment, but also has a better moisture regulating effect because it does not squeeze. The mixing of pulp fibers is the same as in the second embodiment.

Abstract

Constructional materials and interior materials produced by using non-wooden plant fibers as the main component. Namely, processed board-type products made of fibers which can be produced on a mass scale, are less expensive, have a high toughness and a high flexibility, are highly safe and nontoxic in case of using as housing materials, can be easily degraded by bacteria or enzymes when disposed by allowing to stand in soil as such, and generate no harmful substance in combustion. Concrete frames, wall pulp materials and fusuma (sliding paper door) pulp materials obtained by forming a sheet with the use of a pulp material comprising non-wooden cellulose obtained from cyclic plants of Gramineae, plants of Palmae, buckwheat of Polygonaceae or a mixture thereof, and heating under elevated pressure or drying.

Description

technical field [0001] The present invention particularly relates to a building material and a mounting material which are made by papermaking with non-wood fiber material as a main component. Background technique [0002] In the past, among the papers represented by plate-shaped processed products made of plant fibers, Japanese paper was made by collecting bast fibers from cultivated shrubs such as mulberry and mitsumata, and adding a binder (paste). On the other hand, coniferous trees and broad-leaved trees are mainly used as materials in order to manufacture office paper and packaging paper in large quantities at low cost, and the raw wood is crushed and boiled with alkali to obtain pulp. The prepared pulp is freed and beaten in water, and a sizing agent (fiber binder), filler, etc. are added to make paper. Paper-made thin paper is mainly used as interior decoration materials such as wallpaper or partition paper, and paper-made hard thick paper is combined with other aux...
