Abstract

The present invention has an object to provide a heat insulating plate made of waste glass fibers.

To this end, the waste glass fibers are pulverized in an airtight space, and the crushed waste glass fibers are mixed with an adhesive to be compressed into a plate and adhered to a plastering material on the surface to provide a manufactured insulation plate.

The present invention has the effect of the waste glass fiber which is not disposed of by waste disposal as the current technology and the effect of pollution-free recycling of waste which is a pollutant.

Description

Nonflammable board using used glass fiber.}

An object of the present invention is to provide a heat insulating plate made of waste glass fibers with no pollution by producing a heat insulating plate using waste glass fibers as pollution.

In addition, to provide a heat insulating plate made of glued glass fiber as an adhesive material does not scatter.

Conventionally, various heat insulating materials have been provided using glass fibers, but there is no glass fiber laminate made of plates using glass fibers. When manufactured from plywood, it is economically less expensive than the manufacture and sale of sheets and other uses. In particular, the disposal of waste glass fibers relies on landfill because they cannot be disposed of by incineration.

However, there is a big problem that there is a problem of limitation in the landfill and the landfill, which is exposed to the ground and scattered and causes serious harm to the human body. There are many studies to solve this problem, but it is not solved. I'm doing it.

Accordingly, the present invention has been made in order to revive the above demands, and has an object to provide a heat insulating plate, which is a building material, in which waste glass fibers are safely crushed in a hermetic space and bonded to the waste glass fibers crushed with an adhesive to be recycled into plates.

Explanation of symbols on the main parts of the drawings

1: plasterer. 2: glass fiber.

3: adhesive material.

In order to achieve the object as described above, the subject innovation consists of a plate composed of waste glass fibers (2), adhesives (3), and a plaster (1).

The waste glass fibers 2 are crushed and adhered by the adhesive 3, compressed into a plate shape, and dried to form a plaster.

The construction method of the insulation board is described in detail as follows.

The waste glass fibers (2) are transported by a closed vehicle from a waste place to be unloaded in a closed stockyard, and the unloaded waste glass fibers are crushed by a grinder installed in an enclosed space and stored in a cyclone. The pulverization of the fibers is introduced into the mixer and at the same time adhesive is injected into the mixer from the glue reservoir. At this time, the waste glass fiber and the adhesive has a weight ratio of 95% -99%: 1% -5%. The mixture of the waste glass fiber pulverized powder and the adhesive mixed in the mixer is injected into the forming plate and compressed into a plate to form a plate.

The formed plate is transferred to a roller dryer in a drying chamber by a roller conveyer, dried with heat of 70 degrees Celsius to 200 degrees Celsius and solidified. And it is transferred to the roller to the plastering material adhesive to bond the plastering agent is made of glass fiber plywood of 2mm-50mm. The drying roller is a roller equipped with steam or electric heating wires inside the roller.

Mixers, injection machines, drying rollers, compressors, molds, etc. of the machines that make up the insulation plate using the waste glass fibers above, use the existing facilities. In addition, the non-combustible adhesive in the above uses a commercially available non-combustible oil-based or water-based resin adhesive.

Example 1.

1 is a cross-sectional view of a heat insulating plate made of waste glass fibers of the present invention.

According to the above drawing, the waste glass fibers are mixed by the adhesive and solidified into a plate shape, so that the waste glass fibers are composed of the waste glass fibers and the adhesive. The above construct is made by the following example.

0.9kg of waste glass fiber is put into a grinder and crushed into 0.5mm-20cm size, and 0.1kg of nonflammable adhesive is put into the above ground waste fiberglass. The mixture is stirred to be sufficiently mixed, injected into a plate mold, and compressed. The compressed waste glass fiber sheet is pushed with a roller heated at 90 degrees Celsius-120 degrees Celsius to be dried, and then transferred to a non-combustible plastering material adhesive to bond the plastering material to form an insulation board of 65 cm x 65 cm x 1 cm.

It has the effect of safely disposing of waste glass fiber, which is a malignant pollutant, as a building material.
