Abstract
The invention discloses a kind of flyash modified imitative basalt fibre, raw material compositions are as follows: flyash 85%-93%, heat stabilizer 5%-15%, plasticizer 0.8%-1%, dispersing agent 0.3%-0.6%, impact modifier 0.4-0.7%, total amount 100%, the percentage are mass percent.The present invention adds dispersing agent, heat stabilizer, plasticizer and impact modifier in right amount according to demand, it interacts during by coal ash for manufacturing fiber, make coal ash for manufacturing at the formation preferable network former of the structure i.e. nuclear structure of sial skeleton when fiber, guarantee the chemical stability and excellent mechanical property of fiber, contribute to form long fibre, and the thermal stability and water resistance of fiber can be improved, basalt fibre is substituted to reach the characteristic that basalt fibre has.
Description
Technical field
The present invention relates to a kind of preparation methods of flyash modified imitative basalt fibre.
Background technique
Basalt ore by magma formation basic ore.High temperature, hyperbaric environment and eruption during magma formation
When ambient pressure fall sharply, cause a large amount of ablations volatilization of the unstable component of magma, final magma condensation is in the ore of earth's surface.With pole
High chemical stability and thermal stability.
Continuous basalt fiber using pure natural basalt ore as raw material, be prepared by melt drawing technique one
Kind novel high-performance inorfil.High specific strength and specific modulus, excellent high temperature resistance and corrosion resistance.In aviation, boat
It, build, build the road, the fields such as auto industry, electronics industry have broad application prospects.
Due to basalt mine limits throughput, basalt ore can largely be substituted by, which being badly in need of now, does basalt fibre
Raw material.Currently, most suitable alternative materials are flyash.Flyash is the wastes such as thermal power plant and heat supply factory, has fire
Mountain ash active particle, main component be SiO2 and Al2O3, with basaltic ingredient very close to, be the three wastes important composition it
One.About 80,000,000 tons of China's annual output or more, except 30% in addition to producing cement or porous brick building materials, remaining to become solid waste
Object causes significant damage to environment.So replacing basalt manufacture basalt fibre both to can protect the Black Warrior for flyash modified
Rock mineral products, which can also recycle Ash Utilization, turns waste into wealth, and reduces environmental pollution.
Summary of the invention
