Novel fiberboard with heat storage function

Abstract

The invention discloses a novel fiberboard with a heat storage function, and relates to the technical field of fiberboard processing. A method comprises the following steps that (1), sodium alginate and chitosan are adopted as wall materials, pretreated flaky aluminum oxide particles obtained after stearic acid surface treatment are introduced, and an outer wall material solution is obtained; (2), the pretreated zirconium oxide nanoparticles modified by benzoic acid are introduced into a polyacrylate emulsion, and a polymerization reaction is carried out with a phase change material, an initiator and an aqueous solution containing a dispersant and a surfactant to form a suspension; (3), the outer wall material solution is dropwise added into the suspension, and a glutaraldehyde solution is added to obtain a capsule phase change material; and (4), the plant fiber, the capsule phase change material, solid paraffin, urea-formaldehyde resin adhesive, carboxymethyl cellulose and methyl tetrahydrophthalic anhydride are evenly mixed and then laid, and the fiberboard with the heat storage function is obtained. The fiberboard is excellent in performance, and the heat release time is prolonged by 85% or above compared with a common fiberboard.

Description

technical field [0001] The invention belongs to the technical field of fiberboard processing, and in particular relates to a novel fiberboard with heat storage function. Background technique [0002] With the development of society, energy and environmental problems are becoming more and more serious, and single-function building structures and decorative materials can no longer meet the requirements of building energy conservation. Although multi-layer structure walls and multi-layer structure decoration materials achieve the effect of heat preservation and heat insulation by adding thermal insulation materials, general decoration materials have small heat capacity and low heat storage capacity, which cannot delay room temperature changes and excellent heat preservation effects. The development of building energy-saving and thermal insulation composite materials with high heat storage capacity is of great significance for improving the comfort of the living environment and ...

For example, Chinese patent CN2016111540407 discloses a phase change energy storage honeycomb panel and its preparation method. The phase change energy storage honeycomb panel uses ternary fatty acid eutectic / expanded graphite composite phase change energy storage The honeycomb structure is a core board, medium density fiberboard or solid wood veneer is used as the surface board, the phase change unit is filled into the honeycomb of the honeycomb board, and epoxy resin is used as the binder to prepare by cold pressing; but the phase change The energy storage honeycomb panel is based on aluminum honeycomb structure as the core panel, medium density fiberboard or solid wood veneer as the surface panel, and the phase change unit is filled in the honeycomb of the honeycomb panel. structure, so that the phase change energy storage honeycomb panel is not only heavy, but also the surface plate will form additional thermal resistance to the phase change unit, resulting in a low utilization rate of phase change heat
