Description
Technical field
The invention belongs to wooden boards production technical field, particularly a kind of is raw-material application timber with medium density fibre board (MDF).
Background technology
Medium density fibre board (MDF) is with the plant fiber material of small diameter grade log, felling, industrial wood waste and non-wood, through section, boiling, fiber separation, dry after-applied Lauxite or other adhesive be suitable for, more a kind of artificial board made after hot pressing; Its thickness is not less than 1.5mm, density generally 500-880 kilogram of/cubic metre of scope, and thickness is generally 2-30 millimeter.
The surface fiber of medium density fibre board (MDF) is all for exposed state, and wood-fibred can suck moisture in timber as suction pipe, causes lumber fibre to expand, occurs the muscle phenomenon that rises, and makes the surface of fiberboard that projection occur, destroys material.
Summary of the invention
Technical problem to be solved by this invention is: for the deficiencies in the prior art, adopt a kind of coating process, the fiber painting charging being exposed to outer surface is wrapped up, fiber so just can be made to avoid contact wetting, avoid the muscle that rises, keep the quality of medium density fibre board (MDF).
For solving the problems of the technologies described above, the technical solution adopted in the present invention is a kind of medium density fibre board (MDF) application timber, and by batching, sand milling, preheating, painting medium material, first application, overcoating fills and totally seven large steps of spraying paint complete, and it is characterized in that concrete grammar is as follows.
(1) prepare burden: getting granularity according to weight portion is 1200-1500 object wood powder 6-7 part, wheat flour 3-4 part, the rear mashing off of clear water 7-8 part mixing, obtains wood powder medium material; Granularity is 800-1000 object heavy carbonic calcium powder 100-120 part, solids content is 30%-35% white glue with vinyl 30-40 part is got in addition and wheat flour 7-8 part mixes according to weight portion, and then add ethyl acetate 8-12 part and be fully uniformly mixed, obtain rendering charging; Get granularity is 800-1000 object heavy carbonic calcium powder 100-120 part, solids content is 20%-25% white glue with vinyl 40-50 part in addition again and wheat flour 7-8 part mixes, then add ethyl acetate 8-12 part and be fully uniformly mixed, obtain overcoating charging.
(2) sand milling: by smooth for the sand papering of medium density fibre board (MDF) surface 400#-500#.
(3) preheating: by medium density fibre board (MDF) preheating 6-8 minute at the temperature of 95-105 DEG C, and make top layer water content between 5%-8%.
(4) be coated with medium material: wood powder medium material is put into coating machine, brush on medium density fibre board (MDF) after preheat equably, then medium density fibre board (MDF) is directly put into flowing baking box to toast, baking temperature is 75-80 DEG C, baking time is 10-12 minute, then take out natural curing 15-18 hour, then polish with sand mill.
(5) just application: coating machine is put in rendering charging, by coating machine by rendering charging be equably coated be contained on medium density fibre board (MDF), then the baking of flowing baking box is directly put into, baking temperature is 75-80 DEG C, baking time is 10-12 minute, then take out natural curing 15-18 hour, then use the sand papering of 800#-1000#; Repeat 3 times.
(6) overcoating dress: coating machine is put in overcoating charging, by coating machine by overcoating charging be equably coated be contained on medium density fibre board (MDF), then the baking of flowing baking box is directly put into, baking temperature is 60-65 DEG C, baking time is 25-30 minute, then take out natural curing 15-18 hour, then use the sand papering of 1600#-1800#; Repeat 3 times.
(7) spray paint: by the medium density fibre board (MDF) appearance use environmental protection paint even application after sand milling, then maintenance 18-24 hour, namely obtains medium density fibre board (MDF) application timber.
The contact medium that to the invention has the beneficial effects as follows with superfine wood powder be sheet material and coating, more easily makes painting charging and medium density fibre board (MDF) combine together fully; Be coated with charging with appropriate calcium bicarbonate, white glue with vinyl, wheat flour and curing agent manufacture simultaneously, make to be coated with charging exquisiteness, to moisten, strong adhesion; Painting charging point two kinds of proportionings are made rendering charging and overcoating charging, the low rendering of water content can be made to feed and be first attached on medium density fibre board (MDF), rendering be feeded and fast medium density fibre board (MDF) is sealed and solidify; Then application overcoating charging, can make application timber keep smooth in appearance fine and smooth; Medium density fibre board (MDF) is carried out sand milling and preheating and drying before application, make to be coated with above charging is more easily attached to, be coated with charging not containing pollutants such as formaldehyde; Through inspection; this product coating tissue is fine and smooth fine and close; fire resistance is strong; application is even, and impact resistant capability is strong, good water-proof effect; do not rise muscle phenomenon; substantially increase performance and the scope of application of medium density fibre board (MDF) like this, its due economic worth can be given full play to, and for protecting wild timber and forest to create conditions.
