Description

Insulation board

technical field

The invention relates to a thermal insulation board, which is used for sticking on the outer side of a building wall for thermal insulation.

Background technique

There are following defects in the thermal insulation board in the prior art:

1. As time goes by, insects and centipedes are easy to breed in the insulation board, which is very unhygienic, and they will crawl into the house of the residents, causing certain troubles;

2. Especially on the roof or where there is a design on the building, birds often inhabit and discharge feces on the roof or shape;

3. The sound insulation and thermal insulation effects of the thermal insulation board in the prior art are not ideal, and further improvement is needed.

Contents of the invention

In view of this, the technical problem to be solved by the present invention is to provide a thermal insulation board which is not easy to breed insects and can greatly reduce the number of birds.

In order to achieve the above object, the present invention adopts following technical scheme to realize:

A thermal insulation board, wherein, the thermal insulation board comprises a cement board decorative layer on the outer layer, a cement board base layer for connecting a building wall, and a sound insulation board connected between the cement board decorative layer and the cement board base layer The heat preservation middle layer, the cement board decorative layer is composed of the following components in parts by weight: 95 parts of cement, 4 parts of sarcocarpus powder and 1 part of neem bark powder.

As a preference: the sound insulation and thermal insulation middle layer includes components and parts by weight: 40 parts of building gypsum, 10 parts of plant fiber, 8 parts of lithium chloride sol, 3 parts of gypsum retarder, and 11 parts of white silicate Cement clinker; the chemical composition of the above-mentioned building gypsum is β-hemihydrate gypsum as the main component, without any pre-added powdery cement. The molecular formula of β-hemihydrate gypsum is βCaSO ₄ 1/2H ₂ O; The composition and weight percentage of the lithium sol are: 10% LiCl and 90% polyacrylic superabsorbent resin sol, and the plant fiber is reed stalk powder obtained by crushing reed stalks.

As can be seen from the foregoing technical scheme, the beneficial effects of the present invention are:

Compared with the prior art, the present invention adds the powder of the sarcocarpus and neem bark powder to the decorative layer of the cement board, and it has been proved by experiments that usually adult insects or moths are reluctant to approach the addition of the sarcocarpus. The cement board decorative layer of powder and neem bark powder can effectively reduce the probability that insects and moths etc. lay eggs and reproduce at the insulation board, thereby greatly reducing the breeding rate of insects. After the insulation board of the powder of the sarcocarpus, there are few birds stopping at the top of the building and the shape design, which effectively avoids the pollution of the building by bird feces. At the same time, by setting the sound-insulating and heat-insulating middle layer as the above-mentioned components and proportions in the present invention, the sound-insulating and heat-insulating middle layer produced has excellent sound-insulating effect and good heat-insulating effect.

detailed description

In order for those skilled in the art to further understand the features and technical content of the present invention, please refer to the following detailed description of the present invention.

The invention provides a thermal insulation board, wherein the thermal insulation board comprises a cement board decorative layer on the outer layer, a cement board base layer for connecting building walls, and a cement board base layer connected to the cement board decorative layer and the cement board base layer The middle layer of sound insulation and heat preservation between them, the cement board decorative layer is composed of the following components in parts by weight: 95 parts of cement, 4 parts of sarcocarpus powder and 1 part of neem bark powder.

Wherein, the manufacturing method of the decorative layer of the cement board is very simple. It only needs to mix the cement, the powder of the sarcocarpus and the powder of the neem skin, and stir it with water, put it into a mold to form a plate, and dry it to obtain the cement. Finished board decorative layer; then use cement to make the cement board base layer, that is, add water to stir the cement, put it into another mold to make a plate, dry, and get the finished cement board base layer; Add it to a small mixer and stir for 5 to 10 minutes, then add water and stir for 10 to 20 minutes to make a thick and uniform slurry, and then fill the slurry between the cement board decoration layer and the cement board base layer ( The decorative layer of cement board and the base layer of cement board can be put into a mold and fixed in advance, and then the slurry is filled between the two through the feeding port on the mold), and then dried and formed to obtain a thermal insulation board that meets the specifications. The insulation board is dried in an oven at about 50 degrees for 5 to 10 hours. Of course, this is just a processing method, and other methods in the prior art can also be used, which is not limited here. As long as the three can be made into a composite layer structure that meets the requirements.

Moreover, the sound-insulating and heat-preserving middle layer preferably includes components and parts by weight: 40 parts of building gypsum, 10 parts of plant fiber, 8 parts of lithium chloride sol, 3 parts of gypsum retarder, and 11 parts of white silicic acid Salt cement clinker; the chemical composition of the above-mentioned building gypsum is β hemihydrate gypsum as the main component, without any pre-added powdery cement. The molecular formula of β hemihydrate gypsum is βCaSO ₄ 1/2H ₂ O; the above chlorine The composition and weight percentage of the lithium chloride sol are: 10% LiCl and 90% polyacrylic superabsorbent resin sol, and the plant fiber is reed stalk powder obtained by crushing reed stalks. The present invention adopts the sound insulation and heat preservation middle layer of the above-mentioned components and proportions, not only the connection between the cement board decoration layer and the cement board base layer is more closely connected, because the traditional sound insulation and heat preservation middle layer is usually made of plastic foam material, which is not compatible with heat preservation The connection between the decorative panel and the base panel of the board is very loose, resulting in poor overall mechanical strength of the insulation board, and it is easy to be damaged by impact during use, but this problem does not occur in the present invention, and the connection between the three is not only more firm , and the middle layer of sound insulation is between the decorative layer of the cement board and the base layer of the cement board. The multi-layer design, as well as the ratio of components and weight parts, make its thermal insulation effect better than ordinary thermal insulation boards on the market, and has good mechanical strength and is not easy to damage, and its sound insulation effect is at least 2 times better than ordinary thermal insulation boards. 1.5 times better than ordinary insulation boards on the market.

The sound-insulating and heat-preserving middle layer of the present invention uses building gypsum as the main matrix cementing material, adds plant fiber and lithium chloride sol with good moisture absorption capacity, and simultaneously adds white Portland cement clinker and prolonging material solidification to improve the strength of the material. Time gypsum retarder processed.

The preparation process of lithium chloride sol of the present invention is as follows:

It is prepared by mixing 10% LiCl with 90% polyacrylic superabsorbent resin sol. The polyacrylic acid superabsorbent resin sol is made by mixing superabsorbent resin and distilled water at a ratio of 1:99 (mass ratio).

Examples of the middle layer of sound insulation and heat preservation:

However, the above descriptions are only preferred feasible embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Therefore, all equivalent structural changes made by using the content of the description of the present invention are also included in the scope of the present invention.
