Abstract
The utility model relates to the technical field of a heat insulation product outside an external wall of a building, in particular to a mineral wool composite wood cement board. The mineral wool composite wood cement board comprises a surface layer and a core layer, wherein the surface layer is made of a wood cement board; and the core layer is made of a mineral wool strip board. Since the structure that the surface layer is made of the wood cement board and the core layer is made of the mineral wool strip board is adopted, fireproof performance of a heat insulation system outside the external wall can be improved, service life can be prolonged by more than 50 years, and living comfort is improved.
Description
Technical field
The utility model relates to the outer insulating product technical field of skin, refers in particular to a kind of mineral wool complex cement woodwool board.
Background technology
Energy saving building is the developing direction of current builing industry, and wherein, the outer insulation of exterior wall is to implement one of important content of building energy conservation.Current, the widely used external wall outer insulation product of China is based on the heat-insulation system of EPS (expanded polystyrene plate), and its advantage is a high insulating effect, and the coefficient of thermal conductivity of EPS only is 0.04W/mK, and supporting construction technology is ripe relatively.But along with popularizing of EPS system, people also recognize its deficiency gradually, show:
(1) fire-protection rating of EPS is not enough, and its fire-protection rating is B2, has serious potential safety hazard when the building breaking out of fire;
(2) be lower than application life of building service life; The cementing agent life-span of using in the EPS outer heat preservation system, the life-span of the cementing agent that quality is higher also was no more than 30 years at 20-25, and after adhesive failure, heat-insulation system can come off;
(3) residence comfort is poor; Poor because of the water vapor permeability of intrasystem EPS and polymer mortar, cause indoor steam and extraneous unbalance, reduced the comfort level of human body;
(4) cementing agent of EPS system use is strongly professional, and general construction company is difficult to grasp, and causes final effect uneven in each engineering.
The construction of tradition sound insulation system is to carry out the keel construction earlier at body of wall or top, in cavity, add rock wool then, on keel, impose damping material again, form good soundproof effect, based on the defective of single sound-absorbing material and the complexity of construction technology in such sound-absorbing system, need make improvements.
Therefore, based on the defective of above-mentioned existing external wall outer insulation product, need improve existing external wall outer insulation product.
The utility model content
The purpose of this utility model is to provide a kind of mineral wool complex cement woodwool board at the deficiencies in the prior art, and this mineral wool complex cement woodwool board can solve the defective of EPS outer heat preservation system in the existing external wall outer insulation product.
For achieving the above object, the utility model is achieved through the following technical solutions:
Mineral wool complex cement woodwool board comprises surface layer and sandwich layer, and surface layer is a wood wool cement board, and sandwich layer is a mineral wool slitting plate.
The thickness of described surface layer is 5mm-15mm.
Described sandwich layer is that unit weight is 120Kg/m
3-150Kg/m
3Mineral wool slitting plate.
The thickness of described sandwich layer is 25mm-100mm.
The beneficial effects of the utility model are: the employing surface layer is that wood wool cement board, sandwich layer are the structure of mineral wool slitting plate, can improve the fireproof performance of external thermal insulation system, increases to reach more than 50 years service life, improves residence comfort.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Element and Reference numeral:
1---surface layer;
2---sandwich layer.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
See Fig. 1, the utility model mineral wool complex cement woodwool board comprises: surface layer 1 and sandwich layer 2, and surface layer 1 is a wood wool cement board, sandwich layer 2 is a mineral wool slitting plate, also can be rock wool slitting plate.Folder is established mineral wool slitting plate in two wood wool cement boards, cement is cementing agent, former wood wool is an aggregate, make sheet material through the high pressure one-shot forming, compound by with the cement wood wool, make mineral wool overcome the unsettled intrinsic problem of its physical arrangement, make sheet material and obtained favorable rigidity, also obtained excellent affinity simultaneously with cement mortar.
The thickness of described surface layer 1 is 5mm-15mm.Described sandwich layer 2 for unit weight is: 120Kg/m
3-150Kg/m
3Mineral wool slitting plate.
The thickness of described sandwich layer 2 is 25mm-100mm.
As shown in FIG., the thickness of surface layer 1 is 5mm, and sandwich layer 2 is 120Kg/m3 for unit weight, and the thickness of sandwich layer 2 is 30mm.
The utility model can also can be used as abatvoix and be widely used in all kinds of fields, shop, office, life area as the sound insulation functional material.
Advantage of the present utility model has: (1), fire protecting performance are good, and fire-protection rating is the A level; (2), service life is long, can substantially identical with building service life; (3), the water vapor diffusion performance is better than EPS, residence comfort is good; (4), belong to general construction techniques based on the outer heat preservation system construction method of this product, quality is convenient to control; (5), applied range: have insulation, sound insulation, mildew-resistant, the function such as termite-proof; (6), belong to general construction techniques based on the sound insulation system construction method of this product, quality is convenient to control, and sound insulation system is easier; (7), environmental protection, environmental protection reaches the E level, several unmatchful human harmful substances' discharging.
