Description
Technical field
The present invention relates to a kind of sheet material and preparation method thereof, especially, a kind of macromolecular material sheet material and preparation method thereof with flame retardant properties.
Technical background
Existing ultrahigh molecular weight polyethylene(UHMWPE) (UHMW-PE) is the viscosity-average molecular weight that is polymerized under the effect of catalyzer by ethene, divinylic monomer greater than 2,000,000 thermoplastic engineering plastic.This product has the excellent comprehensive performance, and wear-resistant, low temperature resistant, corrosion-resistant, self-lubricating, anti-adhesive, shock resistance are good.
Although ultrahigh molecular weight polyethylene(UHMWPE) has aforesaid many excellent properties, it also exists some weakness, and easy firing for example is so its use range is restricted.
Summary of the invention
First purpose of the present invention is that the contriver has overcome above-mentioned shortcoming through concentrating on studies, and has developed alloy composite combustion-proof plate.
Another object of the present invention is the preparation method who has proposed alloy composite combustion-proof plate.
For realizing above goal of the invention, the present invention adopts the technical scheme of following its technical problem of solution:
The prescription that alloy composite combustion-proof plate of the present invention adopts comprises following component in percentage by weight: 69～78.0wt% ultrahigh molecular weight polyethylene(UHMWPE); 0.5～1.0wt% molybdenumdisulphide; The 8.0-10.0wt% weisspiessglanz; 0.5～1.0wt% bromine; 10.0～12.0wt% liquid crystal plastics; 2.7～7.0wt% red phosphorus; 1.0～2.0wt% silica gel.
Described liquid crystal plastics is a kind of novel high-performance engineering plastics that grow up at the initial stage eighties, and English by name: Liquid Crystal Polyester abbreviates LCP as.
In each component, ultrahigh molecular weight polyethylene(UHMWPE) is a body material, and weisspiessglanz, bromine and red phosphorus are the fire retardant with synergistic effect, and silica gel is lubricant.
The preparation method of alloy composite combustion-proof plate of the present invention is as shown in Figure 1: prepare material by said ratio, high-speed stirring is sent into the vibration of stone platform after evenly earlier and is mated formation and enter thermocompressor then and carry out hot pressing, sends into chilling press again and colds pressing, last demoulding moulding.
When material is sent into thermocompressor, can use thermal oil to heat.
Specifically, preparation method of the present invention is after preparing material by said ratio, mixes with homogenizer, and whipping temp is 75～85 ℃; Send into after stirring and enter thermocompressor after the vibration of stone platform is mated formation, be heated to the compound fusing then, be forced into 12～18MPa, pressurize after 45 minutes～10 hours (according to the difference of thickness, dwell time is also different) basic forming, send into the chilling press cooling again, enter stripper apparatus at last, the demoulding moulding.
The prepared alloy composite combustion-proof plate of the present invention has self-lubricating, corrosion-resistant, shock resistance, wear-resisting, fire-retardant and extremely low premium propertiess such as water-intake rate, fully solved the bonding in the material processing, sticking stifled problem, and sheet material self has good flame retardancy.
