Bamboo fiber plate for internal wall thermal insulation and preparation method thereof

Abstract

The invention relates to a bamboo fiber plate for internal wall thermal insulation and a preparation method thereof. The bamboo fiber plate is prepared from the following raw materials in parts by weight: 60 to 70 parts of bamboo fiber, 10 to 25 parts of modified basalt fiber, 5 to 10 parts of epoxy resin, 3 to 5 parts of polyurethane resin, 1 to 10 parts of diluent, 1 to 10 parts of curing agent,and 0.05 to 0.1 part of p-hydroxybenzoic acid. The preparation method comprises the steps of firstly adding the epoxy resin and the polyurethane resin into the diluent, fully stirring and uniformly dispersing, adding into uniformly mixed bamboo fiber and modified basalt fiber, adding into the epoxy resin, and fully stirring to obtain a premix compound; adding the curing agent, and fully stirringagain to obtain a material preparation; then pouring the material preparation into a mold, and hot-press molding; and finally demolding after natural cooling to obtain a finished product. The bamboo fiber plate prepared through the method provided by the invention not only is good in heat storage, heat insulation and sound insulation, but also has excellent mechanical performances such compressionresistance and bending fracture resistance.

Description

technical field [0001] The invention belongs to the field of board materials, and in particular relates to a bamboo fiber board for interior wall heat preservation and a preparation method thereof. Background technique [0002] Bamboo fiber is a kind of cellulose fiber extracted from naturally growing bamboo. It is the fifth largest natural fiber after cotton, hemp, wool and silk. The constituent units of bamboo fiber products can be single fiber cells or fiber bundles. Due to the concave-convex deformation of the cross-section of the bamboo fiber, it is covered with approximately oval-shaped pores and is highly hollow. It can store heat, keep warm and soundproof, and at the same time have natural antibacterial, antibacterial, mite, deodorant and anti-ultraviolet functions. The houses built with this material have the characteristics of warm in winter and cool in summer, so it is more and more used in new environmentally friendly decorative building materials, which is in l...

AI Technical Summary

Problems solved by technology

Due to the concave-convex deformation of the cross-section of the bamboo fiber, it is covered with approximately oval-shaped pores and is highly hollow. It can store heat, keep warm and soundproof, and at the same time have natural antibacterial, antibacterial, mite, deodorant and anti-ultraviolet functions. The houses built with this material have the characteristics of warm in winter and cool in summer, so it is more and more used in new environmentally friendly decorative building materials, which is in line with the development trend of quick assembly of the whole house; however, the bamboo fiberboards currently on the market are mainly divided into two types , the first kind of plywood is made of bamboo fiber glued together, which preserves the excellent characteristics of bamboo fiber, but it is indeed insufficient in performance such as compression resistance and bending resistance, and the other is bamboo fiber glass magnesium board, which is made of powder Inorganic materials such as coal ash and bamboo fiber are mixed and bonded by cement. Due to the use of materials such as fly ash and cement, the compressive and bending fracture resistance of the product is significantly improved, but the bamboo fiber is greatly reduced. Therefore, it is necessary to develop a bamboo fiber board with good thermal insulation and sound insulation performance, excellent hardness and wear resistance and its preparation method.
