Manufacturing process of flame-retardant rubber-plastic sponge insulation board

Abstract

The invention belongs to the technical field of insulation boards, and particularly relates to a manufacturing process of a flame-retardant rubber-plastic sponge insulation board. The manufacturing process comprises the following steps of 1, preparing a rock wool fiber pile: carrying out high-temperature melting on basalt ore to form a liquid, forming rock wool fibers through blowing of a centrifuge, and stacking on a conveying belt of a settling chamber to form the rock wool fiber pile; step 2, pressing the flame-retardant insulation board: pressurizing the stacked rock wool fiber piles through a pressurizing roller, feeding the rock wool fiber piles into a curing oven, mixing the rock wool fiber piles with a binder, a dust-proof agent and a water repellent to generate the flame-retardantinsulation board, and then cooling and curing the flame-retardant insulation board; and step 3, attaching a rubber-plastic sponge layer: attaching the rubber-plastic sponge layer to the surface of the flame-retardant insulation board prepared in the step 2, wherein the step 3 is completed by cooperation with a manufacturing device for the flame-retardant rubber-plastic sponge insulation board. Rubber-plastic sponge can be tightly attached to the surface of a rock wool board, glue is evenly distributed on the surface of the rock wool board, and the attaching effect of the rubber-plastic spongeis improved.

Description

technical field [0001] The invention belongs to the technical field of rubber-plastic insulation boards, and in particular relates to a preparation process of flame-retardant rubber-plastic sponge insulation boards. Background technique [0002] The thermal insulation board is a flat plate fixed on the outer wall of the building to play a thermal insulation effect. The rock wool board is a common thermal insulation board. The rock wool board is processed by high-temperature melting. flame retardant. Rubber sponge is a porous structure material with holes all over the material; it has low density, excellent elasticity and flexibility, and has high shock absorption, sound insulation and heat insulation performance. A layer of rubber is usually attached to the flame retardant insulation board. sponge. At present, the rubber and plastic sponge is mainly attached to the surface of the rock wool board manually. In the actual production process, the artificial rubber and plastic ...

AI Technical Summary

Problems solved by technology

[0004] The invention provides a preparation process of a flame-retardant rubber-plastic sponge insulation board, aiming to solve the following problems of artificially attaching the rubber-plastic sponge: (1) During the continuous transportation of the rock wool board, it is difficult to manually attach the rubber-plastic sponge Attached to the wavy surface of the rock wool board, which reduces the attachment effect; (2) During the process of gluing the surface of the rock wool board, the glue is easy to form a blockage at the glue outlet, resulting in uneven glue output from each glue outlet , which in turn leads to uneven adhesion of the rubber-plastic sponge on the rock wool board, which also reduces the effect of attachment
