Abstract
A high-filled hard PVC floor tile is made up of PVC (18-22 wt.%), stabilizer (1-1.35), plasticizer (7-9), filler (60-72), additive (1-2) and lubricant through mixing and extruding.
Description
The invention provides a kind of high filling rigid polyvinyl chloride wood floor bolck and process equipment.
There is the flexible wood floor bolck of two kinds of polyvinyl chloride in China at present, first kind is multiple film PVC floor tile, thickness is 1.25～1.5 millimeters, be three layer construction, basic unit is the soft layer of polyvinyl chloride and filler blend, and the middle level is color printing paper or plastics patterned layer, thick 0.08～0.1 millimeter, the top layer is the rigid polyvinyl chloride transparent sheet, thick 0.08～0.1 millimeter, above-mentioned multiple film floor tile essence is the plastic sheet with soft basic unit, and its surface easily produces permanent indentation, and easily because of the multiple bonding not firm aliquation of film, second kind is quartz floor brick, and thickness is about 1.2 millimeters, and the mechanical strength of quartz floor brick is low, color is single, does not have reveal the exact details decorative pattern and zyklopisch decorative pattern etc.
The equipment of the above-mentioned flexible wood floor bolck of present known production has high-speed mixer and plastic extruder, the said equipment is when the big raw material of mixing proportion of filler, because of filer content big, compound melt the refining viscosity too big, material easily takes place in mixing process to be decomposed, burn phenomenon, and extrudate can produce " melt fracture " and " squeezing the limit breaks " phenomenon inevitably, thereby all adopt device fabrication rigid polyvinyl chloride wood floor bolcks such as banbury, mill, calender abroad, but the structure of the said equipment is extremely complicated, costs an arm and a leg.
The objective of the invention is to overcome above-mentioned deficiency and a kind of high filling rigid polyvinyl chloride wood floor bolck and process equipment are provided.
The invention provides a kind of high filling rigid polyvinyl chloride wood floor bolck, with the polyvinyl chloride is raw material, through adding stabilizing agent, behind plasticizing agent, sliding agent, filler and the additive, batch mixing in cold blending machine, send into that mixing extruder is mixing to be extruded, be pressed into sheet products at last, the proportioning of each component following (weight % than):
Stabilizing agent 1～1.35
Plasticizing agent 7～9
Filler 60～72
Additive 1～2
Raw material can directly add cold blending machine and the mixing extruder from powder among the present invention, obtains mixingly uniformly under controlled shear rate, makes " infiltration " between its resin and filler, " coating " good, promptly obtains wood floor bolck by the tablet press machine compression molding again.
Above-mentioned each component also can adopt following proportioning (weight % ratio):
Stabilizing agent 1～1.35
Plasticizing agent 7～9
Filler 60～72
Additive 1～2
The product that blowing agent 1～11 is made by above-mentioned prescription is applicable to as the inner wall decoration plate.
Above-mentioned polyvinyl chloride adopts polyvinyl chloride 3 types and polyvinyl chloride 5 type blending; Stabilizing agent is three salt, disalt, hard barium or heat stabilizer; Plasticizing agent is a chlorinated paraffin wax; Additive is a polyethylene---the blend of vinyl acetate, chlorinated paraffin wax and haloflex.Adopt chlorinated paraffin wax to replace expensive dibutyl ester or dibutylester or epoxy soybean wet goods plasticizing agent and expensive coupling agent among the present invention,, can reduce the cost of wood floor bolck greatly as organic metatitanic acid fat etc.
