Abstract

The invention relates to a method for producing integrated wall whose inner core is the thermal-insulated materials as rice/wheat straw. Said method comprises: adjusting the water content of rice/wheat straw; using chaff-cutter to process them into units; removing fine one and the dust and sending them to the storehouse; feeding them into glue mixer to be plated with glue; packing and molding, then thermal compressing in the thermal compressor; the thermal-insulated material that has been thermal compressed is sliced, to be composed with directional flakeboard into composite rice/wheat straw thermal-insulated mateirla as the inner wall of integrated wall. The invention has the advantages of simple process and lower cost, while it can save infield and protect environment.

Description

Rice/rice/wheat straw thermo-keeping material is the method for manufacturing combined wall of inner core
Technical field
The present invention is that a kind of rice/rice/wheat straw thermo-keeping material is the method for manufacturing combined wall of inner core.Belong to the man-made board technology field.
Background technology
Hundred million tons of stalk 6-7 are produced in the whole nation per year, and wherein 60% is rice wheat straw, is about 400,000,000 tons, be used for also field simultaneously, the stalk of biogas and feed accounts for 30-40%, and the 60-70% of total amount (about 2.5 hundred million tons) does not obtain utilizing, to such an extent as to the peasant at autumn harvest crop straw burning in season, causes public hazards and remains incessant after repeated prohibition.Yet, with rice/wheat straw stalk be raw material to make body of wall be the basic outlet that solves the stalk problem because with rice/wheat straw stalk be raw material manufacturing body of wall not only consumption is big, technical feasible, economically feasible, market also can be accepted.With rice/wheat straw stalk is that raw material are made the use that body of wall substitutes the part clay brick, and what meet country develops a circular economy the policy of building a conservation-minded society.In order to protect farmland, protect environment, national policy limits the use of clay brick energetically, encourage growth lightweight wall material.At present, be not the combined wall of inner core as yet with rice/rice/wheat straw thermo-keeping material.
Summary of the invention
The objective of the invention is to protect farmland and protect atmospheric environment, development lightweight wall material, proposing a kind of is the method for manufacturing combined wall of inner core with rice/rice/wheat straw thermo-keeping material.With rice/wheat straw stalk is that raw material are made the use that body of wall substitutes the part clay brick, and it is in light weight to be with rice/wheat straw stalk that the body of wall of raw material manufacturing has, insulation, characteristics such as easy for installation.
Technical solution of the present invention: its technological process: rice/wheat straw stalk → cut-out → feed bin → applying glue → mat formation → hot pressing → saw → with surfacing compound → check.Specifically, processing step branch
One, carries out moisture content adjustment (moisture content 10-15%) to purchasing the rice/wheat straw stalk that comes;
Two, be processed into the long unit of 50-100mm with chaffcutter;
Three, remove thinner particle and dust.Rice after the processing/wheat straw stalk is sent to feed bin and stores;
Four, the rice that comes out from feed bin/wheat straw stalk need be sent into and carry out applying glue the glue mixer, because rice/wheat straw stalk outer surface has one deck wax, the conventional adhesive that uses in wood-base fibre and particle panel material is not suitable for this type of sheet material.For this reason, need select isocyanate adhesive (resin added accounts for the 2-3% of rice/wheat straw stalk weight) for use;
Five, the rice after the applying glue/wheat straw stalk unit be carried out mat formation, moulding, send into press, during hot pressing temperature 140-160 ℃, hot pressing time is 0.5-0.8min/mm, the hot pressing maximum pressure is 0.2Mpa.
Six, after the rice after the hot pressing/wheat straw stalk wall heat insulation material jagsaw is cut out, again with hard plasterboard, or the oriented wood chipboard material is compound, and (thickness of rice/wheat straw stalk wall heat insulation material is 50-100mm, and the thickness of hard plasterboard or oriented wood chipboard is that 8-20mm one-tenth rice/rice/wheat straw thermo-keeping material is the combined wall of inner core.The thermal conductivity factor of this combined wall is 0.20-0.40w/mk.
Advantage of the present invention: technology is easy, easy to operate, small investment, instant effect, and the basic outlet of solution stalk problem is that raw material manufacturing body of wall is technical feasible, economically feasible with rice/wheat straw stalk, market also can be accepted.With rice/wheat straw stalk is that raw material are made the use that body of wall substitutes the part clay brick, saves and ploughs, and the protection environment meets national encourage growth lightweight wall material policy.
The specific embodiment
Embodiment 1
One, the wheat straw stalk is carried out moisture content and be adjusted into 10%;
Two, be processed into the long unit of 50mm with chaffcutter (model ZCQ3);
Three, remove thinner particle and dust.Wheat straw stalk after the processing is sent to feed bin and stores;
Four, the wheat straw stalk that comes out from feed bin need be sent into the glue mixer (model BB2868) and carry out applying glue, selects isocyanate adhesive (resin added account for wheat straw stalk weight 2%) for use;
Five, the wheat straw stalk unit after the applying glue be carried out mat formation, moulding, send into press (model NBY-1), temperature is 140 ℃ during hot pressing, hot pressing time is 0.5min/mm, the hot pressing maximum pressure is 0.2Mpa.
Six, after the rice straw wall heat insulation material jagsaw after the hot pressing is cut out, be combined into the combined wall that the rice straw insulation material is an inner core with the oriented wood chipboard material again; The thickness of rice/wheat straw stalk wall heat insulation material is 50mm, and the thickness of hard plasterboard or oriented wood chipboard is 8mm, and the rice straw insulation material is that the thermal conductivity factor of the combined wall of inner core is 0.20w/mk.
