Problems solved by technology

Because the high-density glass wool board is made of glass fiber resin wool by heating and pressing, and the bonding resin is phenolic resin, with a content of 8-10%, the high-density glass wool board is brittle and has low flexural strength. , especially containing 8~10% organic resin, which reduces the non-combustible performance of the material, and will release the harmful substance formaldehyde for a long time, pollute the indoor environment, and is not conducive to safety and environmental protection

Abstract

The invention relates to a high-density glass fiber board and a production method thereof which are used for reinforcing and protecting surface layers of soft heat-insulating materials of shipboard cabins and belong to the technical field of inorganic materials. The preparation method comprises the following steps of: preparing alkali-free glass fibers into an alkali-free glass fiber blanket; and taking a bonding agent, a thickening agent and a water repellent agent to prepare a bonding agent; centrifugally drying, rolling, compounding and setting alkali-free glass fiber cloth and the alkali-free glass fiber blanket to obtain the high-density glass fiber board. The high-density glass fiber board is formed by needling continuous fibers, so that the fiber blanket has a three-dimensional network structure and has strong tensile strength; and in addition, the bonding agent is used for compressing and setting, so that the strength of the product can be greatly improved. After the surface is impregnated with the alkali-free glass fiber cloth and is integrally formed with a fiber board, the product has functions of reinforcing boards and fireproof boards; and a heat insulating layer is integrated with a protecting layer, so that the construction procedure is simplified and the construction cost of projects is reduced.

Description

technical field [0001] The invention relates to a high-density glass fiber board and a preparation method thereof, which are used for strengthening and protecting the surface layer of soft heat-insulating materials in ship cabins, and belong to the technical field of inorganic materials. Background technique [0002] At present, the cabin thermal insulation layer of various ships, due to the particularity of the structure, generally uses soft thermal insulation materials as the thermal insulation layer, such as rock mineral wool, glass wool, ceramic wool, etc. Two methods are generally adopted in the design of the outer sheath. One is to install the outer protective fireproof board after installing the heat insulation layer. The advantage is that the surface is smooth and the decoration effect is good. The disadvantage is that the structure is complex, no sound absorption, and the cost is high. The other is to apply two layers of flame-retardant white cloth on the surface a...
