Abstract
Description
Technical Field
[0001] The present application relates to the technical field of building materials, and in particular to a resin composition and a basalt continuous fiber lightweight board. Background Art
[0002] Due to the house fires and other accidents that have occurred in recent years, people are paying more and more attention to the fire resistance of house materials. At present, the common fireproof boards are inorganic insulation boards. Although they have good fireproof effects, they have poor toughness and are difficult to construct. The other is organic insulation materials. However, the combustion level of organic insulation materials is far from meeting the standards, and they are prone to produce harmful gases that cause suffocation in the event of a fire.
[0003] At present, the main problems faced by fireproof panels on the market include complex processes, difficult construction, and poor three-dimensional effects. Specifically, the production process of fireproof panels is complex and inefficient; fireproof panels have shrinkage properties, and if the process is not paid attention to during construction, they are easy to debond, and the requirements for adhesive glue are high. In addition, traditional fireproof panels cannot be used alone, and usually need to be pasted on the surface of artificial boards and wood. Because the characteristics and shrinkage ratio of the base material are quite different from those of the fire-resistant veneer material, thermal expansion and contraction may cause delamination, cracking, or deformation of the door panel. These problems increase the difficulty and complexity of production and construction, and affect the use effect and safety of fireproof panels.
[0004] A document reportedly discloses a homogeneous fireproof insulation board and a preparation method thereof, and the specific steps are as follows: accurately take each component, first add the fire-resistant flame-retardant inorganic material to the fire-resistant flame-retardant binder, then add the dispersant, coupling agent, and flame retardant to fully stir and disperse; then put the obtained mixture into a mixer, inject a foaming agent to foam; then mix the above-obtained mixture with expandable polystyrene particles and fully stir and disperse, then inject the foamed homogeneous slurry into a mold, place it on a drying rack for natural curing for 10-15 hours, stack it for 10-15 hours after demolding, and finally cut, polish and level it. The fireproof board has the problems of insufficient strength and complicated preparation process. Summary of the invention
[0005] In order to solve the above technical problems, the present application provides a resin composition and a basalt continuous fiber lightweight board.
[0006] In a first aspect, the present application provides a resin composition for preparing a basalt continuous fiber lightweight board, specifically comprising the following components in parts by weight: 12-20 parts of YKCR-1 resin, 95-110 parts of basalt chopped fibers, 5-10 parts of foaming material, 1.1-2 parts of an auxiliary agent, and 1.1-2 parts of a dispersant; The basalt chopped fibers are mixed with 0.2-0.5 mm basalt chopped fibers and 1-2 mm basalt chopped fibers in a weight ratio of 20-28:1-3.
[0007] The present application utilizes specific weight portions of resin, basalt chopped fibers, foaming materials, additives, and dispersants as raw material components to obtain a resin composition for preparing a basalt continuous fiber lightweight board, thereby obtaining a basalt continuous fiber lightweight board with excellent mechanical properties and good flame retardant properties.
[0008] In the technical solution provided in this application, resin is used as the matrix material, which can provide strong bonding force to firmly bond the basalt chopped fibers together to form a solid board structure; this structure not only has high compressive and tensile strength, but also can effectively resist external impact and vibration, ensuring the stability and durability of the fiberboard. The addition of foaming material can significantly reduce the density of the fiberboard, achieve lightweight, and facilitate transportation and installation. The addition of additives can improve the fluidity and processing properties of the resin, making it easier to operate and control during the preparation process; this can not only improve production efficiency, but also reduce energy consumption and raw material waste in the production process, thereby reducing costs. The use of dispersants can ensure that the basalt chopped fibers are evenly dispersed in the resin to avoid agglomeration and sedimentation; this helps to improve the overall performance and product consistency of the fiberboard, ensuring that each fiberboard has the same high-quality characteristics.
[0009] Among them, by using basalt chopped fibers of different lengths and mixing them in specific proportions, a resin composition with a multi-level reinforcement effect is prepared, which can achieve balanced reinforcement in different stress directions and improve the comprehensive mechanical properties of the final product; at the same time, it improves the interfacial bonding performance between the fibers and the resin matrix, which will help to improve the mechanical strength, durability and environmental aging resistance of the resin composition.

[0011] Preferably, the basalt chopped fibers are mixed with 0.2-0.5 mm basalt chopped fibers and 1-2 mm basalt chopped fibers in a weight ratio of 22-25:1.5-2.5.
[0012] The basalt chopped fibers are composed of a mixture of 0.2-0.5 mm basalt chopped fibers and 1-2 mm basalt chopped fibers in a weight ratio of 23:2.
[0013] Preferably, the auxiliary agent is selected from one or more of ANTEKA-6161A auxiliary agent, ANJEKA6110 auxiliary agent, and Anjeka6182 auxiliary agent.
[0014] Preferably, the dispersant is selected from one or more of AG-42 dispersant, AG-46 dispersant, and AG-316 dispersant.
[0015] In a second aspect, the present application provides a basalt continuous fiber lightweight board prepared using the above-mentioned resin composition.
[0016] In a third aspect, the present application provides a method for preparing the above-mentioned basalt continuous fiber lightweight board, which specifically comprises the following steps in sequence: feeding the continuous fiber cloth into the resin composition for pre-impregnation; Then, the basalt continuous fiber lightweight board is obtained after rolling, 150-250° C. curing treatment and cutting.
[0017] Preferably, the continuous fiber cloth is basalt fiber cloth, the fiber cloth type is twill or plain cloth, and the gram weight is 100-200g / m 2 .
