Abstract

The invention aims at the shortcomings that the current culture stones are heavy in weight, high in cost or poor in thermal insulation properties and have poor bondability with the building blocks, masonries and the like, are easily spalled, have short service lives and the like, and provides a rigid polyurethane foam (RPUF) culture stone and a production method thereof. The RPUF product with goodbondability, good thermal insulation property, light materials and long service life is obtained by improving the culture stone raw materials, production steps and technological conditions, which issuitable for the indoor and outdoor decoration in various environments.

Description

technical field [0001] The invention relates to a cultural stone suitable for indoor and outdoor decoration and a production method thereof. Background technique [0002] Cultural stone refers to the plate used for indoor and outdoor decoration, which is divided into natural cultural stone or artificial cultural stone. Natural cultural stones are stones mined in nature, among which slate, sandstone, and quartz stone are processed to become a kind of decorative building materials. Although natural cultural stone has the most natural color and texture, due to the limitation of materials, it is generally heavy in weight, and its production cost is high, so its application range is limited. Artificial cultural stone is generally made of silicon-calcium, gypsum and other materials. It imitates the shape and texture of natural stone, and has the characteristics of light texture, no mold, no combustion, and easy installation. However, the thermal insulation performance of artific...
