Method for manufacturing insulating plate from basalt fibers

Abstract

The invention provides a method for manufacturing an insulating plate from basalt fibers, which comprises the following steps of: fully soaking the front and back surfaces of single-layer basalt fibercloth by a mixture, dehydrating and flattening for the first time after soaking for multiple times, changing a soft state into a flat hard state, cutting into a cloth plate with a set length, stacking a plurality of layers of cloth plates, and repressing into a high-density whole plate; and meanwhile, heating, drying and dehydrating for the second time, cutting the whole plate again, carrying outdouble-sided grinding and polishing, sending out of the plate making machine, and arranging. The method for manufacturing the insulating plate from the basalt fibers is simple in step and flexible tooperate, and the manufactured insulating plate is reliable in quality, firm and durable and has obvious advantages in high-temperature stability, low-temperature stability, moisture resistance, deformation and overall fatigue resistance.

Description

technical field [0001] The invention relates to a method for an insulating board, in particular to a method for making an insulating board from basalt fiber. Background technique [0002] Fiberglass insulation board is a relatively mature technology. There are dozens of methods and formulas for making fiberglass insulation boards. It is also a common insulation board for circuit boards. Usually, glass fiber materials are made of pyrophyllite, quartz sand, and limestone. Six kinds of ores, dolomite, boronite, and boronite, are made by high-temperature melting, wire drawing, winding, weaving and other processes, which is very complicated. However, the material used in glass fiber is too complicated. Although it is widely used, because the material used is too complicated and the processing and production are laborious, it is not suitable for some high-end fields, such as new energy vehicles, aircraft, aviation fields, some materials such as pyrophyllite, limestone, Dolomite i...

[0002] Fiberglass insulation board is a relatively mature technology. There are dozens of methods and formulas for making fiberglass insulation boards. It is also a common insulation board for circuit boards. Usually, glass fiber materials are made of pyrophyllite, quartz sand, and limestone. , dolomite, boronite, and boronite are made of six kinds of ores as raw materials through high-temperature melting, wire drawing, winding, weaving and other processes, which are very complicated.

However, the material used in glass fiber is too complicated. Although it is widely used, because the material used is too complicated and the processing and production are laborious, it is not suitable for some high-end fields, such as new energy vehicles, aircraft, aviation fields, some materials such as pyrophyllite, limestone, Dolomite is not as good as a single pure natural and impurity-free basalt fiber insulation board in terms of high temperature resistance and flame retardancy
