Description
Technical field
The invention belongs to building element, more particularly to a kind of novel glass fiber enhance cement composite heat preserving wallboard and its
Production method.
Background technique
For frame structure building, building enclosure itself does not need to bear very big load, it is only necessary to which satisfaction is gone along with sb. to guard him
The function of main structure.Common practice is first to be puzzled the wall of building enclosure using light block etc., then in wall
The construction of insulating layer is carried out outside body.The method of this outer patch insulating layer on building enclosure exterior wall, long construction period, environment are dirty
Dye is big, and overall cost is high, is particularly present the defects of service life is short, fire protecting performance is poor, external decoration is influenced by the external world.Also adopt
With light steel skeleton heat-insulation system or polyurethane foam technology, although light steel skeleton heat-insulation system solves above-mentioned defect,
But due to cost height, it is difficult to promote the use of；The problems such as polyurethane foam technology is inconvenient there is also construction simultaneously, promote the use of by
To certain limitation.
In addition, the straw refuse quantity that China's agricultural generates is very big, but its utilization rate is very low.In many regions, people
Stalk is burned in the ground directly, the waste of stalk resource had both been caused in this way, and also seriously polluted environment.
Polystyrene products are also seen everywhere, but the utilization rate of poly styrene wastes is extremely low, polystyrene products
It is completely degraded in nature and needs long time, while can also cause secondary pollution to natural resources such as soil, water sources.
In recent years, with the rapid development of our country's economy, required resource also increased severely therewith, especially the mine of industry pair
Producing resources requirement is even more to greatly increase, and which results in excess load minings, has in turn resulted in a large amount of tailing accumulation.Tail
For mine as a kind of mine solid waste, utilization rate is very low.The accumulation of tailing, occupies a large amount of arable land, and the heavy metal of discharge has
Malicious harmful substance etc. causes serious pollution to natural resources such as soil, water sources.
Therefore how asking for building enclosure external thermal insulation is solved by waste utilizations such as stalk, polystyrene, tailings and simultaneously
Topic, becomes urgent problem to be solved.
