Abstract

The invention relates to a cover plate and a manufacturing method thereof, which includes the following steps: a perlite granule mixing step, a press molding step, and a baking step to complete at least one cover plate. This cover plate has the effects of sound absorption, heat insulation, fire prevention and heat preservation. Moreover, the invention adopts granular perlite, so its effect is much higher than that of traditional cover plates.

Description

Cover plate and manufacturing method thereof

The present invention relates to a cover plate obtained by processing granular perlite and a manufacturing method thereof.

In recent years, the disadvantages of decorative material sound-absorbing panels used in workshops are that they are fragile, deformed, and have poor sound insulation effects. Furthermore, in the production plants of various industries, it is often seen that there are various pipelines for conveying fluids. Some fluids to be conveyed must be conveyed smoothly in a specific high temperature range. When the pipeline is heated, the temperature outside the pipeline will also increase, resulting in the high heat of the surrounding environment outside the pipeline, which is really inappropriate. Furthermore, whether it is the noise generated when the fluid in the pipeline flows, or the sound of other equipment when it is running, materials that can be heat-insulated and sound-proof are required as barriers.

In order to overcome the above-mentioned problems, the present invention provides a method for manufacturing a cover plate, which includes the following steps: a stirring step of perlite particles, a pressing step, and a baking step.

Among them, the perlite particle mixing step involves mixing perlite particles with a particle size between 2 cm and 5 cm with water glass and a waterproofing agent for at least 1 minute and 30 seconds, wherein the perlite particles The weight ratio of granules, water glass and waterproofing agent is 120:18:1.

Press-forming step: Put the mixed perlite particles, water glass and waterproofing agent into a press-forming machine, and press-form at least one plate with a pressure higher than 150 tons.

Baking steps: put the plate in a roasting machine for about x hours, set the humidity below 5 degrees (please ask the unit), and the baking temperature between 120 degrees and 150 degrees Celsius to complete at least one cover.

Wherein, before the perlite particles are stirred, glue is sprayed on the perlite particles to increase their stability.

The cover plate manufactured by the above method has better sound insulation and heat insulation effects.

Hereinafter, the description will be made through embodiments and drawings.

Fig. 1 is a schematic flowchart of an embodiment of the present invention.

Please cooperate with the method of manufacturing the cover as shown in the figure. The method of this embodiment includes the following steps: a perlite particle mixing step S1, a compression molding step S2, and a baking step S3.

Wherein, the perlite particle stirring step S1 is to stir perlite particles with a particle size between 2 cm and 5 cm, water glass and water repellent for at least 1 minute 30 seconds or 2 minutes or 2 minutes 30 seconds. According to the current actual experimental results, 2 minutes is the best.

In addition, the weight ratio of the perlite particles, the water glass and the waterproofing agent is 120:18:1.

Press molding step S2: Combine the mixed perlite particles, water glass and waterproof The agent is placed in a compression molding machine, and at least one plate is molded by a pressure higher than 150 tons.

Baking step S3: Put the board in a baking machine for about x hours, set the humidity below 5 degrees (please ask the unit), and the baking temperature between 120 degrees and 150 degrees Celsius to complete at least one cover .

Furthermore, before the perlite particles are stirred, glue is sprayed. After stirring it with water glass and water repellent, it can bond with other materials more stably.

The cover plate made by the above method can achieve effective noise isolation and heat insulation, and can be applied to the wall surface of a factory or home to generate a good environment.

The perlite particle mixing step S1, a pressing step S2, and a baking step S3 are the method for manufacturing the cover plate as described in claim 1, wherein the cover plate has a mass of 250 to 280 kg/m3.

In the foregoing, specific embodiments of the present invention have been described with reference to the drawings. However, those of ordinary skill in the art can understand that various changes and substitutions can be made to the specific embodiments of the present invention without departing from the spirit and scope of the present invention. These changes and replacements fall within the scope defined by the claims of the present invention.
