Composite board for high temperature mixture product mold and production process

Abstract

Belonging to composite boards for molds and production processes, the invention provides a composite board for a high temperature mixture product mold and a production process. The composite board is composed of an outer wall structural layer and an inner wall structural layer which are an ordinary plate, a pyrophillite and high temperature glue mix, a mica plate, and a flame retardant polycarbonate film respectively. The ordinary plate is steel plate, high strength rigid plastic plate or wood plate. The production process includes: stirring pyrophillite and high temperature glue fully, then laying the mix on the surface of the ordinary plate, covering the pyrophillite and high temperature glue mix with the mica plate, and performing compression moulding, bonding the flame retardant polycarbonate film on the mica plate surface by high temperature glue, and carrying out vacuum bubble removal treatment, thus forming the four-layer structure composite board. The composite board for the high temperature mixture product mold can eliminate the influence of a high temperature mixture to the product mold, ensures the mold temperature stability, balances the mixture internal and boundary temperature gradient, effectively guarantees each direction homogeneity and surface smoothness and finish of test pieces, greatly improves the product success rate, and saves material and time cost.

Description

technical field [0001] The invention relates to a composite plate for a mold and a production process, in particular to a composite plate for a high-temperature mixture product mold and a production process. Background technique [0002] At present, in the field of civil engineering, similar simulation materials are mostly used in indoor physical test research. Among them, many materials need to be poured under the hot melt state of the binder, and there are also many materials that need to be stirred and poured under high temperature. It is poured in a liquid state and cooled and solidified to form a rock-like material that meets the required physical and mechanical indicators. The test research is based on "Engineering Rock Mass Test Method Standard" (GBT50266-2013) and "Highway Engineering Rock Test Regulations" (JTG_E41-2005) using standard specimens (Φ50×100mm, 50×50×50mm, 50×50×100mm , 70×70×70mm, 100×100×100mm, 150×150×150mm), and some non-standard size test pieces a...
