Embodiment

[0032] An easy-to-install polyurethane foam insulation material, characterized in that: it uses a warp-knitted spacer fabric as the skeleton, and the warp-knitted spacer fabric has an upper layer, a lower layer and a connecting layer, and both the upper layer and the lower layer have mesh holes, wherein the yarn of the lower layer The spacer yarns of the connecting layer and the connecting layer are arranged intermittently in the width direction of the fabric, and the spacer yarns are regularly passed through the lower bar and the connecting layer bar, so that the warp-knitted spacer fabric has an open hollow section that runs through the longitudinal direction. Insert a heat-insulating connector on this section, bond its bottom to the top surface of the open hollow section (that is, the inner surface of the upper layer of the warp-knitted spacer fabric), inject the reactive mixture of polyurethane foam into the warp-knitted spacer fabric, and react The mixture is injected thro...

Abstract

The invention relates to an easy-to-install polyurethane foam insulation material and its preparation method and installation method. A warp-knitted spacer fabric is used as a skeleton, and the warp-knitted spacer fabric has an upper layer, a lower layer and a connecting layer, wherein the yarns of the lower layer are separated from the connecting layer. The yarn is arranged intermittently in the width direction of the fabric, so that the warp-knitted spacer fabric has an open hollow section that runs through the longitudinal direction, and a heat-insulating connector is inserted in this section, and the snap-fitting piece is installed on the wall to connect with the heat-insulating parts to snap together. By utilizing the double-needle bed warp knitting process to weave warp knitted fabrics with open hollow sections as the skeleton of polyurethane foam insulation materials, it can effectively solve the problem that the connection between polyurethane insulation materials and fixing parts is not stable enough, the installation steps are cumbersome, and the foam insulation materials and The technical problem that the combination of the wall surface is not tight enough.

Description

technical field [0001] The invention relates to thermal insulation materials, in particular to an easy-to-install polyurethane foam thermal insulation material and a preparation method thereof. Background technique [0002] At present, there are mainly the following ways to fix building insulation materials on building walls: pasting on the wall, such as using partial nylon expansion nails, organic compound or inorganic foam insulation materials, or mixed mineral expansion Particle insulation board; apply metal skeleton on the wall first, and then fill it with insulation material; use multi-layer foam insulation material to embed installation parts; set protrusion-shaped connectors or grooves on the surface of the foam material and the wall to connect. However, the connection effect of the above-mentioned fixing method is not good, the installation steps are cumbersome, and the combination of the foam insulation material and the wall surface is not tight enough.
