A kind of preparation method of nano edging material
Technical field
The present invention relates to a kind of preparation method of finishing material, relate to a kind of preparation method who is applicable to the nano edging material that furniture, kitchen tools, house decoraton, vehicle aircraft train are decorated more specifically.
Background technology
China is the country that timber lacks, and at present, except a small amount of top-grade furniture used the solid wood manufacturing, furniture adopted medium density fiber, wood shavings, wood particle board etc. more usually.These sheet materials are when being divided into the small-sized sheet material of different size by the needs of making furniture, and side promptly exposes fiber, wood shavings, sawdust etc., and is very not attractive in appearance.In recent years, being in great demand of furniture, the edge sealing process during it is produced is finished by special-purpose bag sealer with hot melt adhesive usually.When producing this hot melt adhesive, control fusing point, melt viscosity, set time and the cohesive strength etc. of product.
At present as edging material, how based on polyvinyl chloride (PVC) and material modified.For example Chinese patent CN101176598A discloses the preparation method of a kind of edge sealing of furniture and decoration plastic glue strip; this method of manufacturing technology may further comprise the steps: 1, with PVC or the extrusion moulding of ABS material; 2, cooling and shaping; 3, drying up the substrate backside gluing handles; 4, printing pattern layer and protective layer, 5, rolling vanning.Because base material adopts extrusion equipment to make, the output of edge sealing of furniture and decoration plastic glue strip improves greatly, and quality product is guaranteed.
Chinese patent CN101042016A discloses a kind of making method of novel PVC edge banding strip; this making method is earlier PVC, CaCO3, toughner etc. to be made into base material; pattern-making layer and transparent protective film because base material adopts extrusion moulding, make manufacturing speed fast again.
But these adhesive tape easy-weatherings, and uvioresistant not, the hard fugitive color of variable xanthochromia, the angle that easily collapses not easy to operate on the production technique, cutting unfairness; Product can not be used on the car and boat production; Be used for right angle or acute angle surface curve variation product greatly, adhesive tape is easily lost.
Summary of the invention
In order to overcome the above-mentioned defective of traditional adhesive tape, the invention provides a kind of nano edging material, its raw material comprises:
The PVC powder: the 40-60 weight part,
The ACR:0.4-1.2 weight part,
The CPE:1-3 weight part,
PE wax: the 0.1-0.3 weight part,
Stablizer: the 2.5-3.5 weight part,
The DOP:2-3 weight part,
Nano-calcium carbonate: the 20-30 weight part,
Stearic acid: 0.2-0.6 weight part.
Preferred prescription is:
The PVC powder: 50 weight parts,
The ACR:0.8 weight part,
The CPE:2 weight part,
PE wax: 0.2 weight part,
Stablizer: 2.8 weight parts,
The DOP:2-3 weight part,
Nano-calcium carbonate: 25 weight parts,
Stearic acid: 0.4 weight part.
Wherein stablizer can be an oxidized polyethlene wax.
Can add titanium dioxide 0.2-0.3 weight part or other an amount of toner as required.
The present invention also provides the preparation method of nano edging material.Comprise the steps: 1, PVC powder, ACR, CPE, PE wax, stablizer, DOP, nano-calcium carbonate, stearic acid are directly put into stirrer according to said ratio, 1000-1400 rev/min of stirring is heated to 145-150 ℃ simultaneously; 2, the powder after will stirring is put into tablets press, carries out granulation, produces micelle; 3, micelle is cooled to 50-60 ℃ rapidly through blower fan, inserts storage hopper; 4, the micelle in the storage hopper is dropped into plastics extruder, extrusion moulding, the width and the thickness of the mould control product by different model in the extrusion machine; 5, by cooling tank, utilize cold water to cool off, obtain nano edging material.
Each proportion of raw materials is just found through the big quantity research of technician, only under proportioning of the present invention, just can obtain nano edging material, if the add-on of change one or more raw materials wherein possibly can't obtain nano edging material, for example: the amount of nano-calcium carbonate increases, and this edging material may be burnt in the stirring heating process; If do not add stearic acid, then this edging material can't be extruded.
Adopted nano-calcium carbonate as the raw material of making nano edging material among the present invention, more abundant with material mixing such as PVC, so this nano edging material compares with traditional edging material, and the surface is more smooth, and wear resistance is better, nor easily loses.
In addition, nano edging material of the present invention has durable wear, and moulding is flexible and changeable, smooth and beautiful appearance, and envelope clings advantages such as close, is that indispensable material is decorated by manufacturers such as top-grade furniture, car and boat.Market response is respond well, and supply falls short of demand for product, and economic outlook is considerable.This series products is progressively replacing traditional edging material at present, is the once innovation of edge sealing product.
Embodiment
The nano-calcium carbonate that adopts among the embodiment is the nano-calcium carbonate that Huaming, Jiangxi nano-calcium carbonate company limited produces.
