Abstract
The invention discloses a composite insulation mica plate and a manufacturing method thereof, and relates to an electro-technical mica plate with heat insulation and insulation functions and a manufacturing method thereof. High-temperature insulation fibers and glass fibers are mixed and carded into loose mat type and soaked into adhesive, the mat is dried, the double surfaces of the mat are stuckwith a mica material to be compounded, and the whole is extruded at high temperature to form the plate. Through the composite structure, the composite insulation mica plate integrates the advantagesof various materials such as the insulation fibers, the glass fibers, the mica material and the like, makes up for the deficiency of a single material, remarkably improves the properties such as integral high temperature resistor, insulation, mechanical strength and the like, and can be widely applied in fields such as electric heating equipment, electromechanical protection and the like.
Description
Technical field:
The present invention relates to a kind of electrician's micarex and manufacture method thereof, especially composite insulation mica plate and preparation method thereof that has insulation and insulation function concurrently.
Background technique:
Electro-heat installation is that assurance equipment is safe in utilization, often need to use materials such as insulation board, simultaneously, also need to use heat preserving and insulating material for energy-conservation, yet in the known technology, the sheet material that has insulation or insulating property respectively separately is more common, general insulating material, though have the good insulation performance as micarex etc., but it is heat insulation, resistance to high temperature is limited, and thermal waste is big, and consumed power is too much, and the thermal insulation of thermal insulating material such as ceramic fiber etc. and resistance to high temperature are outstanding, but its insulating property are not ideal enough again, and this influence and restricted the safety and the energy-saving effect of electro-heat installation is if use insulating material and thermal insulating material simultaneously, increase the cost expenditure undoubtedly, and made small product size bigger.
Few open material that has insulation and thermal insulation property simultaneously as Chinese patent 92111289.0 electric and thermal insulating composite material for industry frequency furnace, does not contain asbestos in the known technology, is a laminal composite material that is bonded together and is formed by several layer materials.But its withstand high temperatures and insulating property are unsatisfactory.
Summary of the invention:
Objects of the present invention are to propose a kind of composite structure electrician plate and the making method of this sheet material, i.e. composite insulation mica plate and preparation method thereof of better taking into account heat insulation high temperature resistant and electrical insulation capability.
The measure that realizes objects of the present invention is: high-temperature-resistant thermal-insulation fiber, glass fibre mix and are carded to loose felt type and flood the adhesive drying, and two-sided card closes mica material and carries out compoundly, and high temperature is squeezed into plate.
The invention has the advantages that: pass through composite structure; concentrated the advantage separately of multiple materials such as insulation fibre, glass fibre and mica material simultaneously; remedied the deficiency of homogenous material mutually; significantly promote performances such as whole high temperature resistant, insulation and mechanical strength, can be widely used in various fields such as electric heating equipment, mechanical and electrical protection.
Description of drawings:
Fig. 1 is a production process sketch of the present invention
Embodiment:
Embodiment 1: high-temperature-resistant thermal-insulation fiber, glass fibre mix and are carded to loose felt type and flood the adhesive drying, and two-sided card closes mica material and carries out compoundly, and high temperature is squeezed into plate.
The high-temperature-resistant thermal-insulation fiber comprises ceramic fiber, aluminum silicate fiber, rock wool.
Adhesive is an organic adhesion agent.Mica material is mica paper or micarex.
High-temperature-resistant thermal-insulation fiber, glass fibre mix the resistant to elevated temperatures loose felt of insulation that has that is carded to and enter the tunnel drier bake drying, and the retarder thinner volatilization in the Dry run in the adhesive is removed, and dry back material forms the insulation fibre layer.At this moment, because glass fibre has increased insulation fibre layer and integrally-built combination force, improved mechanical strength.
After dried insulation fibre layer was crossed the two-sided card of complex machine and closed mica material, adhesive oozed out with surperficial mica material bonding, solidified last moulding through the extruding of hotpress high temperature.
The embodiment of the invention is passed through composite structure; concentrated the advantage separately of multiple materials such as insulation fibre, glass fibre and mica material simultaneously; remedied the deficiency of homogenous material mutually; significantly promote performances such as whole high temperature resistant, insulation and mechanical strength, can be widely used in various fields such as electric heating equipment, mechanical and electrical protection.
