Expanded perlite heat-insulation plate modified by early strength agent

Abstract

The invention discloses an expanded perlite heat-insulation plate modified by an early strength agent. The expanded perlite heat-insulation plate is prepared from the following raw materials in partsby weight: 10-30 parts of cement, 1-10 parts of the early strength agent, 20-80 parts of expanded perlite, 10-70 parts of other raw materials, and 10-30 parts of water in a mixed pressing mode, and the early strength agent is tobermorite. By introducing the early strength agent, strength development is fast in the manufacturing process of the heat-insulation plate, and the production efficiency ishigh; and the plate is high in strength and good in durability.

Description

technical field [0001] The invention belongs to the technical field of building materials, and relates to an expanded perlite insulation board modified by an accelerator. Background technique [0002] Expanded perlite insulation board is an insulation board made of expanded perlite as aggregate, supplemented with glue, binder and other auxiliary materials for pressing and curing. With the increasing awareness of energy conservation, expanded perlite insulation boards are increasingly used. However, expanded perlite insulation boards are often damaged, broken, and peeled off during the process of production, packaging, transportation, construction, and service, which is one of the key problems that restrict its application. Contents of the invention [0003] The purpose of the present invention is to provide an expanded perlite thermal insulation board modified by an early strength agent. The modified thermal insulation board has the characteristics of high strength and go...
