Embodiment 1

[0053] see Figure 1-2 As shown, a glass fiber reinforced cement composite thermal insulation wallboard includes a thermal insulation core board 2 and an outer frame enclosed around the sides of the thermal insulation core board, and the outer frame includes a front side panel 3 made of glass fiber reinforced cement, The rear side plate 4 , the left end plate 5 and the right end plate 6 , the insides of the front side plate 3 and the rear side plate 4 are all embedded with galvanized steel wire mesh 1 . The front side board 3 and the rear side board 4 are aligned front and rear. For reliable and convenient connection, the left end surface of the left end plate 5 is concave relative to the left end surfaces of the two side plates, and the right end surface of the right end plate 6 protrudes relative to the right end surfaces of the two side plates.

[0054]In this embodiment, the thickness of the wallboard can be 200mm, the width can be designed in two specifications of 780mm ...

Embodiment 2

[0077] see Figure 3-4 As shown, the wallboard structure is the same as that of Embodiment 1.

[0078] The outer frame is made of glass fiber reinforced cement, and the insulation core board is made of modified concrete. The raw materials of the modified concrete include ordinary Portland cement, tailings sand, water, and modified corn stalks. , polystyrene foam particles, latex powder and water reducer. The modification treatment of corn stalks mainly refers to: first soak corn stalks with 3.5% sodium hydroxide solution for 8-12 hours to remove organic components in corn stalks; then use 1.0% sodium hydroxide solution The sodium silicate solution is uniformly sprayed on the surface of the above-mentioned corn stalks to perform chemical accelerated plugging to increase the bonding force between the corn stalks and the concrete.

[0079] In the modified concrete, the weight parts of ordinary Portland cement, tailings sand, water, latex powder and water reducing agent are as f...

Embodiment 3

[0099] see Figure 3-4 As shown, the difference from Embodiment 1 is that the left end surface of the left end plate 5 is flush with the left end surfaces of the two side plates, and the right end surface of the right end plate 6 protrudes relative to the right end surfaces of the two side plates.

[0100] The outer frame is made of glass fiber reinforced cement, and the insulation core board is made of modified concrete. The raw materials of the modified concrete include ordinary Portland cement, tailings sand, water, and modified corn stalks. , polystyrene foam particles, latex powder and water reducer. The modification treatment of corn stalks mainly refers to: first soak corn stalks with 3.5% sodium hydroxide solution for 8-12 hours to remove organic components in corn stalks; then use 1.0% sodium hydroxide solution The sodium silicate solution is uniformly sprayed on the surface of the above-mentioned corn stalks to perform chemical accelerated plugging to increase the b...

Abstract

The invention discloses a glass fiber reinforced cement composite thermal insulation wallboard and a manufacturing method thereof. The wallboard comprises a thermal insulation core board and an outer frame, wherein the outer frame is made from glass fiber reinforced cement; the thermal insulation core board is made from modified concrete; the modified concrete is prepared from ordinary portland cement, tailing sand, water, modified maize straws, polystyrene foam particles, emulsion powder and a water reducing agent; and the glass fiber reinforced cement is prepared from ordinary portland cement, fly ash, fine sand, coarse sand, glass fibers, a naphthalene-based superplasticizer and water. The manufacturing method comprises the following steps: preparing raw materials, manufacturing the thermal insulation core board, precasting the board in a mold and the like. The manufacturing and production process is simple, the construction procedures are reduced, the wallboard cost is reduced, the environmental pollution is reduced, and industrialized construction production can be realized. The glass fiber reinforced cement composite thermal insulation wallboard disclosed by the invention is applicable to structure enclosure, thermal insulation and decoration of frame structure building external walls.

Description

technical field [0001] The invention belongs to building components, in particular to a novel glass fiber reinforced cement composite thermal insulation wallboard and a manufacturing method thereof. Background technique [0002] For frame structure buildings, the envelope itself does not need to bear a large load, but only needs to meet the functions of the main structure of the envelope. The usual way is to use lightweight blocks to build the wall of the enclosure structure first, and then carry out the construction of the insulation layer on the outside of the wall. This method of pasting the insulation layer on the outer wall of the enclosure structure has a long construction period, great environmental pollution, high overall cost, and especially has defects such as short service life, poor fireproof performance, and external decoration being greatly affected by the outside world. There is also the use of light steel skeleton insulation system or polyurethane foam techn...
