Polyurethane culture stone mold raw materials and polyurethane culture stone processing technology

Abstract

The invention discloses polyurethane culture stone mold raw materials and a polyurethane culture stone processing technology, and relates to the field of rigid polyurethane foam application and culture product preparation processes. The processing technology comprises the steps of preparation of molds, specifically, various natural stones are selected and spliced into a certain pattern, special materials are used for pouring, demolding is conducted after curing, and three molds are prepared for standby for each style; and the polyurethane culture stone production procedure, specifically, raw materials are injected, a procedure is set, a release agent is sprayed, the molds are put into mold cavities, a robot casting machine automatically performs casting, a track operates, the molds are automatically opened after reaching the positioning point, demolding is conducted, trimming and slotting are conducted, and color complementation is conducted. By the adoption of the rigid polyurethane foam board materials, energy conservation and environmental protection are achieved, the rigid polyurethane foam board materials replace nonrenewable natural stone materials, a large number of mountain stone materials do not need to be mined, and the original ecology natural landscape is protected; and the polyurethane culture stone building decorative materials produced by the process integrate heat insulation and decoration, and construction is convenient.

Description

technical field [0001] The invention belongs to the field of polyurethane hard foam application and cultural product preparation technology, and in particular relates to a polyurethane cultural stone mold raw material and a polyurethane cultural stone processing technology. Background technique [0002] The full name of polyurethane is polyurethane, which is a general term for macromolecular compounds containing repeated carbamate groups on the main chain. It is formed by addition polymerization of organic diisocyanate or polyisocyanate and dihydroxy or polyhydroxy compound. In addition to carbamate, polyurethane macromolecules can also contain groups such as ether, ester, urea, biuret and allophanate. Polyurethane materials are very versatile and can replace rubber, plastic, nylon, etc., and are used in airport stores, building materials, automobile factories, coal mines, cement factories, high-end apartments, villas, landscaping, colored stone art and parks, etc. [0003...

Problems solved by technology

When using simple polyurethane boards as insulation materials, the polyurethane boards need to be fixed with mortar, and decorative materials, such as ceramic tiles and marble, are also required. The construction is cumbersome, difficult, time-consuming and material-consuming; the composite polyurethane board is a secondary process The product requires large investment and low efficiency. It needs anchoring and dry hanging for building insulation decoration. The operation is complicated, the cost is high, and the variety and color are single
