Abstract

PURPOSE:To obtain the title lightweight formula martial, outstanding in dryability, mechanical strength of the dried product therefrom, load bearing ability, sound insulation, etc., by mixing sandy pumice, pasty urethane resin, chopped straw or glass fiber and water in specified proportion. CONSTITUTION:Firstly, 60-70wt.% of sandy pumice, 20-25wt.% of a pasty urethane resin and 5-10wt.% of chopped straw or glass fiber are mutually mixed. Thence, the resultant formula material is incorporated with 10wt.% of water followed by kneading, thus obtaining the objective formula material. This material is suitable as a wall-backing material free to extend or contract or a formula material alternative to plasters to be applied on bamboo lathing walls, drying as many as 10-15 days faster than the case for the conventional clay for rough- coating walls, thereby enabling construction period to be shortened with the mechanical strength double that of the conventional plasters.

Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Applicability The present invention relates to a method for producing a construction compound material that can be used as a substitute for rough wall coating and intermediate coating of wall soil on expandable and contractible wall base materials or bamboo walls.

Conventional technology As a conventional technology, in plastering work, the clay applied to the bamboo wall during the construction of rough walls and intermediate coating is sand, red clay,
Natural products such as grass are used. Recently, it has become difficult to extract high-quality natural soil, and the production of bamboo, rope, etc., which are the constituent materials for earthen walls, has slowed down, resulting in a shortage of materials and a shortage of plasterers. Furthermore, during construction, there are many on-site construction processes such as mawatari bamboo (edge) hole drilling. There were problems such as the impossibility of construction on curved surfaces and the long construction period. The most suitable method for Japan's hot and humid climate is the ``earth wall'' construction method. Despite the excellent characteristics of the earthen wall, there were a number of drawbacks to the bamboo wall, as described above. In order to solve this problem, the present invention relates to the patent application No. 50346/1983 [Scalable wall base material] devised by the applicant.

The wall base material of this invention is equipped with a spoon-shaped bending part and a slide technology for adjusting the width, which allows both sides to be coated with a special steel plate of a predetermined thickness, and the steel plate base material is formed by electrodeposition coating. be. In order to use the above-mentioned "scalable wall base material," the applicant has developed a new wall soil to produce an artificial wall soil (compounded material for construction) that can replace natural sand, red clay, and sand. The patent application No. 1983-57380 was filed for ``Method for producing construction compound for rough walls and intermediate coating''. To summarize the manufacturing method, five types of compounding materials are mixed and produced at a predetermined ratio (the amounts and ratios are omitted). Mix the required amount of powdered pumice, the required amount of red clay (clay), the required amount of sizing (straw or glass fiber), and the required amount of powdered cement, and add water to the mixed materials. The gist of this invention was to provide an alternative manufacturing method to ``single wall soil,'' which is artificial by injecting and mixing the required amount. The inventor of the present invention relates to the above-mentioned manufacturing method, which was produced by blending five types of compounding materials and injecting and mixing water as described above. The invention has the following features as an alternative to wall clay. It has excellent strength, heat insulation, workability, hardenability, etc., but on the other hand,
Because it is made from a variety of mixed materials, it is heavy, which puts a load on the frame, and it has poor drying properties, which lengthens the construction period and makes it relatively expensive.

Problem to be solved by the invention In the prior art of the invention, the applicant has
It is a means of mixing and injecting water into a mixture of different types in a fixed ratio. Since the material compounded by this method is applied to the "wall base material," it is heavy, slow to dry and harden, and takes a long time to complete.As a result, it is costly. It had the disadvantage of being relatively expensive. The purpose of the invention is to eliminate the above-mentioned drawbacks, and the product of the present invention produced by the manufacturing method using the least amount of ingredients is lightweight, has quick drying and curing properties, and is light-sensitive. The object of the present invention is to provide an improved production method for construction materials for rough walls and intermediate coatings, which can industrially produce an alternative to wall soil that has good strength, heat resistance, and workability.

Means for Solving the Problems The present applicant has spent many years conducting intensive research into alternatives to wall base materials for the bamboo wall construction method, and has devised the patent application No. 1983-50346 entitled "Scalable and Scalable". We have successfully developed a new wall base material.

Furthermore, as a result of many years of research and development, the inventor succeeded in developing a method for industrially manufacturing "wall soil" for coating on the wall base material, and the present applicant
There is a patent application No. 63-57380 filed on May 12, 1983, concerning ``Method for producing construction compound for rough walls and intermediate coating''.

The present applicant provides the present invention as a technical means that further improves the drawbacks of the above-mentioned means. As mentioned above, the disadvantages are that it is slow to dry and harden due to the fact that it is made with a wide variety of compounded materials, and because it is made with a variety of compounded materials, it has a high specific gravity, which places a load on the frame, which means that it is not lightweight. There were some difficulties. The present invention completely solves the above problem. The present invention, which is the best means, involves a manufacturing method using three types of blended constituent materials and water in predetermined proportions. The gist of the means for solving the above problems is to use sand-like pumice E60-7 (), 20-25% glue-like urethane resin, and 5-10% cut straw or glass fiber. This is a method of mixing the ingredients in proportions and injecting and mixing 10% water into the ingredients.

What has been described above constitutes the present invention.

Function In the present invention, the three types of compounding materials have the following compounding ratios. As the first raw material, sandy pumice (60 to 70

20-30%) and the urethane resin is a polymeric substance used as a synthetic resin for soil stabilization, and it reacts with water, quickly consuming the water, and converting it into resin with the carbon dioxide gas generated, while at the same time forming particles of other substances. As the third raw material, cut straw or glass fiber (5 to 10%) is used as a reinforcing material for molding, and the third raw material is used as a reinforcing material for the rice. Use straw cut into 5-6 cm pieces. Moreover, when using glass fiber, the glass fiber is cut into 5 to 6 cm pieces. Both materials are lightweight and resist tensile forces well. In particular, glass fiber is a nonflammable material that is particularly resistant to fire heat. Water (10%
