Abstract
The invention relates to a building exterior wall heat insulation plate made of reeds and a production method thereof. The heat insulation plate comprises a core layer and an outer layer. The core layer comprises reeds and the outer layer is a polyurethane layer. The core layer consists of reed stalks and at least one bag-like object wrapping the reed stalks inside. The polyurethane layer and the core layer are bonded into a whole. Bag-like objects with reed stalks arranged therein side by side, and bag-like objects with reed stalks arranged therein disorderly are arranged adjacent to each other on the core layer with gaps therebetween. The gaps are filled with polyurethane foaming material and the polyurethane foaming material and the outer layer are integrated as a whole. According to the invention, the natural raw material is utilized fully, while the heating up and pressurization operations are not required during the whole production process. Thus, the energy is saved. Furthermore, due to the adoption of an ordinary die, the manufacturing cost is saved. The reed raw material can be degraded by 100%, and the used polyurethane foaming material can also be recycled. Therefore, the building exterior wall heat insulation plate is a environment-friendly product which meets environment-friendly requirements both in raw material and in production process. Moreover, the building exterior wall heat insulation plate can be produced in large scale.
Description
Technical field
The invention relate to build that the house parts use than the thin type member, relate in particular to the prefabricated units that utilize fiber, wood chip, plant bar or similar item to make, particularly a kind of is raw-material building exterior wall heat preserving plate and production method thereof with reed.
Background technology
In recent years; The building energy conservation project that with energy-saving and emission-reduction is purpose emerges in an endless stream, and field of thermal insulation outside exterior wall utilizes string or cane after oven dry and the preservative treatment quite a few for the example of primary raw material making Outwall thermal insulation board; For example; Notification number is the disclosed a kind of insulating light wall slab of the utility model patent of CN2440871Y, and the skin of warming plate is a screed, and sandwich layer is made up of straw or shrub branch; Reinforcing bar passes the silk screen of burying underground in sandwich layer and two skins and is connected, and Polypropylence Sheet is wrapped in the outside of sandwich layer.The structure that can find out this warming plate is very complicated, and outer field screed easy of crack is damaged, has a strong impact on heat insulation effect, can not degrade after the Polypropylence Sheet of internal layer is discarded and cause environment pollution.Another notification number is the disclosed wheat straw light thermal insulation board that is a kind of with the polyurethane coverlay of the utility model patent of CN2384766Y; To wheat straw be cut into the bar of about 50CM length with hay mover earlier, wheat straw carried out applying glue and stirring, mat formation into the slab of certain specification size after evenly with special-purpose glue mixer; In a special mould, add two component polyurethane then; Put into the slab that makes again, pour polyurethane again into, in the special dies of sealing, foam; Just to have obtained liner be the wheat straw slab in the demoulding after certain density, and skin is the warming plate of polyurethane foam material.We also can find out; Though this warming plate has utilized so good environment-friendly materials of wheat straw and polyurethane to combine; But very loaded down with trivial details aspect the making of slab, and need special-purpose glue mixer and special-purpose mould, increased production cost; Discarded in addition reed is a lot, causes a large amount of raw-material wastes.Another publication number be the patent of invention of CN85108738A disclosed be a kind of be the method that primary raw material is made building prefabricated components with reed and reed rod, laudable here is the raw material that made full use of reed, bits and the reed section pulverized from the reed rod to the reed; Such as, first floor is the precast plate that is formed with the polyurethane bonding by one or more layers reed rod of denuding leaf, precast plate adopts the mode of mold pressing; Because mechanical pressure is big; This one deck can be used as decorative cover, and the second layer is very thin, processes with bitumeniferous compound; The 3rd layer by the reed section of pulverizing in advance, adopts the hot adhesion method to process precast plate.We can see that such three layers of precast plate that is composited are mainly used in the member of doing building, have that in light weight, intensity is big, hard durable; Be used for the building central sill, wallboard, floor; Roof panel etc.; But because starting point is not to make heat-insulation plate for external, so many articles have been done in this invention on the intensity of structure, the mode that adopts mold pressing is exactly in order to control intensity well; And in hot adhesion and mold pressing, all can not avoid having adopted too much adhesive, operation is more loaded down with trivial details in process of production.
Several kinds of above-mentioned methods that adopted string or cane to make warming plate or building unit as primary raw material; On performance, there is not good heat-insulating property; Be difficult to meet the technical standard requirement of country for building heat preservation sheet material, too loaded down with trivial details on the technology of producing, and also manufacturing process still exists too much energy consumption and pollution; Do not utilize the raw material of plant well, caused raw-material a large amount of waste.
Summary of the invention
The policy of the relevant energy-saving and emission-reduction of active response country of the present invention provides a kind of technology simple, makes full use of the reed raw material; Reduce the use amount of adhesive in the whole process of producing; Reduce energy consumption and pollution in the manufacturing process, and the product of most materials degradable or recycling and method, when good heat insulation effect is provided; Comparing with existing product and to reduce the influence that causes in the production phase effectively, is real Life cycle environment-friendly products.
Technical scheme provided by the invention is; A kind of is raw-material building exterior wall heat preserving plate with reed, comprises sandwich layer and skin, and described sandwich layer comprises reed; Skin is a layer of polyurethane; It is characterized in that, described sandwich layer comprise reed rod with at least one with reed rod be wrapped in the inside satchel, described layer of polyurethane and described sandwich layer are bonded to one; The satchel that inside is arranged side by side reed rod is placed next to each other on the position of sandwich layer with the inner mixed and disorderly satchel of placing reed rod; Between the described satchel that reed rod is housed spacing is arranged, described spacing is filled with polyurethane foam material, and said polyurethane foam material and said outer polyurethane layer are an integral body.
