Description

Insulating wall bricks for construction

technical field

The invention relates to the technical field of building materials, in particular to a heat-insulating wall brick for building.

Background technique

Due to environmental considerations, clay bricks have been gradually phased out. However, clay bricks have the advantages of lower cost and higher strength. How to combine clay with other materials in areas where clay is extremely rich in order to achieve better strength bricks is a research focus in the industry. At the same time, with the improvement of people's living standards, people expect more brick bodies with lighter weight and better heat insulation capacity. However, the strength and weight of bricks are often a pair of contradictions, and there is often a certain bottleneck in the heat insulation capacity. After reaching a certain level, it is often difficult to continue to improve.

Contents of the invention

The object of the present invention is to provide a heat insulating wall brick for building, which has the characteristics of better comprehensive performance.

The technical solution adopted in the present invention is: heat-insulating wall bricks for construction, including a brick body, at least 2 rows of left through holes arranged up and down on the left side of the brick body, and at least 2 rows of left through holes arranged up and down inside the brick body; 2 rows of right through holes are arranged up and down, the left side of the left through hole is vertically flat, the right side of the left through hole is in the shape of an arc with the middle protruding to the left and the upper and lower sides protruding to the right. The right side of the right through hole is in the shape of a vertical plane, the left side of the right through hole is in the shape of an arc with the middle protruding to the right, and the upper and lower sides are convex to the left. Meanwhile, the right side of the left through hole coated with a metallic paint layer, and coated with a metallic paint layer on the left side of the right through hole; and, between the left through hole and the right through hole, there is a socket with a rectangular section, and a heat insulating core is inserted in the socket, The heat insulation core body includes an extruded polyethylene material layer in the middle and a foamed resin layer fixed on the left side and right side of the extruded polyethylene material layer by means of glue.

The left through hole and the right through hole are filled with mullite particles, and the surface of the mullite particles is provided with a layer of foam particles.

The brick body is formed by firing the mixed material of silicon carbide and clay.

Compared with the prior art, the present invention has the advantages of better overall performance. The thermal insulation wall brick for building of the present invention uses the staggered distribution of through holes (including left through holes, right through holes, and jacks) to better cut off heat transfer, and the relevant sides of the left through holes and right through holes are uniform. The arc shape effectively reflects heat, and the reflective ability is better after being coated with metallic paint. At the same time, the heat insulation core is combined with extruded polyethylene material and foamed resin, which is not only easy to cut and then inserted into the socket, but also has good heat insulation ability. The left through hole and the right through hole are filled The addition of specially treated mullite particles further enhances the heat insulation capability. And, the silicon carbide material is used as the main material of the brick body, so that the brick body has higher strength.

detailed description

For an embodiment, see FIG. 1 : a heat insulating wall brick for building, including a brick body 10 .

Further speaking:

The left side inside the brick body 10 is provided with at least 2 rows of left through holes 11 arranged up and down, and the inside right side of the brick body 10 is provided with at least 2 rows of right through holes 12 arranged up and down. The left side of the left through hole 11 is a vertical planar shape, and the right side of the left through hole 11 is an arc shape in which the middle part protrudes to the left and the upper and lower sides protrude to the right; the right side of the right through hole 12 It is in the shape of a vertical plane, and the left side of the right through hole 12 is in the shape of an arc with the middle protruding to the right and the upper and lower sides protruding to the left. At the same time, the right side of the left through hole 11 is coated with a metal paint layer, and the left side of the right through hole 12 is coated with a metal paint layer (not shown in the figure). That is, both the right side of the left through hole 11 and the left side of the right through hole 12 have better heat reflection ability, ensuring better heat blocking ability. And, between the left through hole 11 and the right through hole 12 is provided an insertion hole 13 with a rectangular section. Apparently, the height of the insertion hole 13 in the vertical direction is greater than the width of the single left through hole 11 in the vertical direction, and is also greater than the width of the single right through hole 12 in the vertical direction. In this way, a staggered distribution of vias is formed.

As shown in FIG. 2 , a heat insulating core 20 is inserted into the socket 13 . The heat insulation core 20 includes an extruded polyethylene material layer 21 in the middle and a foamed resin layer 22 fixed on the left side and right side of the extruded polyethylene material layer 21 by means of glue. That is, the foamed resin can be prepared in granular form and then mixed with viscose to adhere to the extruded polyethylene material layer 21 . In this way, the thermal insulation capabilities of the extruded polyethylene and the foamed resin are combined, and the positions of the two are rationally allocated, so that the thermal insulation core 20 is convenient for cutting and forming and then for inserting into the insertion hole 13 .

optimized:

As shown in FIG. 3 , the left through hole 11 and the right through hole 12 are filled with mullite particles 31 , and the surface of the mullite particles 31 is provided with a layer of foam particles 32 . That is, the foam can be crushed into granules, and then the mullite particles 31 are bumped and rolled repeatedly in the foam particles after being mixed with viscose. In this way, not only the thermal insulation capability is further enhanced, but also the cost is low, and the metal paint layer will not be damaged.

The brick body 10 is formed by firing the mixed material of silicon carbide and clay. For example, after silicon carbide and clay are pulverized and stirred, added a conventional amount of water and mixed evenly, they are pressed into a mold, then dried naturally, fired in a kiln body at 800-1000°C for 5-8 hours, and then taken out to dry naturally. Just dry. In this way, the brick body is not easy to break and has sufficient strength.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process conversion made by using the description of the present invention and the contents of the accompanying drawings, or directly or indirectly used in other related All technical fields are equally included in the scope of patent protection of the present invention.
