Description

A kind of environmental-friendly walling dalle and preparation method thereof
Technical field
The present invention relates to architectural decoration material fields, are related to a kind of environmental-friendly walling dalle and a kind of environment-friendly type wall The production method of body dalle.
Background technique
Stalk is the general name of mature crops cauline leaf (fringe) part.It is often referred to wheat, rice, corn, potato, rape, cotton Flower, the remainder of sugarcane and other crops (usually coarse food grain) after harvesting seed.The photosynthetic product of crops has More than half is present in stalk, and stalk is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter etc., be it is a kind of have it is multiduty can be again Raw living resources, stalk are also a kind of roughage.
Chinese farmers have long history to the utilization of crop material, only because the low, yield from preceding level of agricultural production Low, stalk quantity is few, and stalk is outer except partially making compost for heap on a small quantity for washer, pasture, most of all to make fuel burn-up ?.With the development of agricultural production, since the 1980s, grain yield is greatly improved, and stalk quantity is also more, adds for China Firewood-saving and coal-saving technology popularization, burn coal and using the universal of liquefied gas, make have largely stalks more than needed in rural area.Scientific skill simultaneously The progress of art, the raising of level of farming mechanization make compost the utilization of stalk by original heap and are changed into straw directly returning to field.In The numerous scientific workers of state have carried out fruitful research to straw-returning.Straw-returning has stack retting returning to the field, crosses abdomen returning to the field, The various ways such as direct returning to farmland.
Currently, the stalk of crops is also less as the use of construction material, in the field of building materials, application is more Some chromatic steel sandwich plates, it be it is a kind of integrate load-bearing, heat preservation, waterproof, finishing novel space enclosing structure material, can be extensive It is needed applied to different buildings, including a variety of building fields such as industrial premises, public building, assembled house, cleaning project.It is color For steel sandwich board using color painted steel strip as plane materiel, self-extinguishing type polystyrene, polyurethane, mineral wool, rock wool etc. are core material, use thermosetting Change the ultralight building board that glue is pressurized in continuous forming machine, be heating and curing, deburring, fluting, the processes such as blanking are combined, Thickness is generally in 25-250mm.But it there is no in conjunction with stalk, the feature of environmental protection still has deficiency, farming this for China For the very big national conditions of object stalk yield, the innoxious process for treating of stalk is still that current scientific worker is needed to need to exert The direction of power research.
China Patent Publication No. is that CN206707169U discloses a kind of heat-preserving decorative wall plate, the heat-preserving decorative wall plate Sandwich layer is no glue stalk board；The lateral surface of the sandwich layer is bonded outer compoboard, the top end face and bottom face point of the outer compoboard Not Xing Cheng inclined-plane, it is tight that the top end face and bottom face of the outer compoboard of two pieces of heat-preserving decorative wall plates pass through the bevel angle matched Fitting；The outer compoboard is bonded fire retardant material plate far from the one side of the sandwich layer；The medial surface adhesive rubber layer of the sandwich layer, The rubber layer has interior compoboard far from the side bonds of sandwich layer, and one end of the interior compoboard is provided with tenon, and the other end is set It is equipped with the groove with tenon cooperation.But this kind of wallboard is bonded using multilayer material, rear is easy with long The phenomenon that now layering falls off.
China Patent Publication No. is that CN107540971A discloses a kind of novel fire retardant exterior wall decorative panel and its preparation side Method, preparation method prepare flame-retardant expanded plate first, while in plate upper surface co-extrusion uvioresistant resin surface layer, formula packet Include following component: polyvinyl chloride (PVC), foaming agent, bio-based materials or inorganic filler, inorganic fire retardants, uvioresistant resin.It should Kind decorative plate of outer wall, under the premise of guaranteeing energy-saving heat preserving, the performances such as flame retardant property, lightweight, sound insulation, anti-aging, heat preservation It is promoted, cost can be reduced and meets the ecological requirements of sustainable development.But its major part used is all some chemistry Substance, the feature of environmental protection are bad.
