JPH02215847A - Compound resin containing fallen volcanic ash - Google Patents

Abstract

PURPOSE:To utilize effectively volcanic ashes and to obtain the title compound resin with excellent heat insulating properties, moldability, noncombustibility, etc., which can be used as a molding material by mixing and kneading dried volcanic ashes with a synthetic resin under heat and pressure and grinding the mixture. CONSTITUTION:Volcanic ashes, obtd. by drying volcanic ashes (fallen volcanic ashes) and, if necessary, screening according to the particle size and drying the screened ashes, are mixed with a synthetic resin, and the mixture is kneaded under heat and pressure and ground.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a composite resin mixed with volcanic ash fall used as a raw material for any molding resin.

In the past, volcanic ash fall was rarely used, and instead was simply buried in landfills, thrown away, and treated as a nuisance to people. Landfill areas are a waste of time, with no plants growing and turning into debris flows.

However, as shown in the Sakurajima volcanic ash fall analysis table published by the Kagoshima Prefectural Industrial Research Institute published in September 1985, the chemical composition [%] Burning raw materials Silicon dioxide Aluminum oxide 1 Arsenic Iron oxide Titanium oxide Calcium oxide Magnesium oxide Sodium Potassium oxide Particle size <200M 200M 100M 100M 48M 48M 28M 28M 14M 4M 8M 8M< is shown.

Ox O40, OX θ ~ 3.0x The manufacturing process of the volcanic ash mixed composite resin is to fully dry and heat-treat the volcanic ash fall as a raw material using the sun or thermal power, and then sort the particle size into 4 types depending on the fl type of molding. To make a mixed composite resin, a homogeneous composite resin is added to the volcanic ash fall, heat treated, stirred under pressure, and the resulting mixture is pulverized to produce a uniform molding material for the mixed composite resin.

By molding using the composite resin material mixed with volcanic ash according to the present invention, the following effects can be obtained.

(1) A molding material with large bulk and specific gravity can be produced.

(2) A molded material with high heat retention can be produced.

(3) Since the particle size of volcanic ash fall is small, moldability is good.

(4) Can do both bottoms.

(5) It has good strength, and the bending strength can be increased by adding other additives.

(6) If you want a gray finish, you don't need any pigment, and if you want a pitch black finish, you don't need much black pigment.

(7) A highly nonflammable molding material can be produced.

(8) Cheap molding materials can be produced with less resin material.

(9) Japan is a volcanic country, and this is good news for regions that are suffering from volcanic ash, as any damage caused by volcanic ash will be covered by national taxes, which will go toward volcanic research costs.

(10) Volcanic ash fall does not change color because it is a natural product.

Claims (1)

[Claims] A molding material characterized by the fact that a uniformly mixed composite resin molding material can be produced by drying volcanic ash (volcanic ash fall), adding a synthetic resin, heat-treating and pressurizing, and crushing the kneaded material while stirring.
