Flame-retardant board and flame-proof PVC stool, however due to the formula of flame-retardant board production and production method and do not conform in the prior art
Reason, especially because the collocation problem of formula makes product stability poor, uses the longevity so that flame retardant property is limited to
Order especially short, waterproofness is also poor, is usually easy by rain erosion and spreading or is scattered scaling-off, affects normal use.
Summary of the invention
The technical problem to be solved in the present invention is to provide the resistances of a kind of properties of product stabilization, flame retardant property height and good waterproof performance
Fire plate and preparation method thereof.
In order to solve the above-mentioned technical problem, flame-retardant board of the invention is made of the following raw material ingredient and formulation by weight ratio: poly-
85~100 parts of ethylene, 60~85 parts of polyurethane, 35~55 parts of nano powder, 25~35 parts of ammonium polyphosphate, wood fibre 20~30
Part, 20~25 parts of resin, 12~18 parts of stabilizer, 10~15 parts of graphene, 7~10 parts of zinc borate, 5~7 parts of chlorinated paraffin, resistance
Fire 4~6 parts of agent, 3~5 parts of antiaging agent, 2~3 parts of foaming agent.
The fiber is staple glass fibre and long glass fiber.
The antiaging agent is triphenyl phosphate or triethyl phosphate.
The fire retardant is diammonium hydrogen phosphate or boric acid and borax.
A kind of preparation method of such as above-mentioned flame-retardant board, comprising the following steps:
A, it weighs by weight such as above-mentioned raw materials, is added in high-speed mixer, is heated to 90-100 DEG C, is cooled to 70-85 DEG C of progress
It is uniformly mixed；
B, uniformly mixed raw material is sent in double screw extruder and is foamed, then squeezed out, control the temperature of double screw extruder
Degree is 210-220 DEG C；
C, fused materials are placed in after vacuum drying oven is dried and cools down, are formed using calender press polish to get flame-retardant board.
The mixing time is 0.3-0.6 hours.
The screw speed of the double screw extruder is 110-130 revs/min.
The drying temperature of the vacuum drying oven is 50-60 DEG C, 2-3 hours cooling time.
After above-mentioned formula and production method, due to being rationally added to nano powder, wood fibre, graphene, chlorine
Thus the ingredients such as fossil waxes and necessary auxiliary agent not only make it have very high intensity, anti-flammability, and manufactured product
With extraordinary waterproof performance, in addition, during the preparation process by the control mode of heating and cooling during high-speed mixer with
And the techniques such as the extrusion of Reasonable Parameters, drying, cooling and sizing make product degrees of fusion especially high in subsequent technique, whole one
Cause property is high, is not in scaling-off the problems such as falling off, substantially prolongs service life.
