Title:
A PROCESS FOR PRODUCING GM-SIDING WITH WOOD GRAIN
Document Type and Number:
WIPO Patent Application WO/2008/148261
Kind Code:
A1
Abstract:
Disclosed is a process for producing composite board, and the said board is glass
fiber reinforced magnesium cement board with wood grain. The process comprises
two steps of preparing a mold with wood grain and preparing glass fiber reinforced
magnesium cement board using the mold. The first step comprises forming film
bearing wood grain, copying the wood grain onto mill rolls, and rolling the formwork
with the mill rolls. The second step comprises steps of preparing MgCl2
solution, agitating the mixed raw materials to obtain slurry, conveying the
molds, scratching the slurry, disposing the raw materials, rolling, separating,
shelving, curing, impregnating the board into water to remove free MgCl2,
cutting, spraying protecting-paint, and so on. The process can produce the board
with three-dimensional appeal, wood grain similar to that of log, and beautiful
appearance. The board produced by the process has advantages of fire proof, water
proof, vermin proof, light weight, compression and bending resistant, high
strength, no moss growing, and so on.
