Problems solved by technology

Although this method can prepare a foamed core material, the foamed body is large and uneven, which affects the strength of the foamed core material.
At the same time, due to the strict temperature control of the foaming agent, it cannot be foamed at a higher temperature, otherwise it will cause foaming failure, so the extrusion temperature will need to be strictly controlled, which will reduce the extrusion efficiency and affect the extrusion process. The speed of the plate

Abstract

The invention discloses a novel fire-proof material. The novel fire-proof material is characterized by comprising matrix resin, a foaming agent and a flame retardant, wherein the novel fire-proof material comprises the following constituents by weight percent: 15% to 60% of polyolefin, 0.5% to 30% of foaming agent and 20% to 80% of flame retardant. The novel fire-proof material provided by the utility model has the characteristics of stronger processing fluidity, easiness in processing, lightness, fire resistance, heat preservation, thermal insulation, cheapness and so on.

Description

technical field [0001] The invention relates to a fireproof material and a preparation method thereof, which is a lightweight fireproof aluminum-plastic board. Background technique [0002] Casualties and property losses caused by building fires have risen sharply in recent years, and the country has also increased the flame-retardant and fire-resistant requirements for building materials. The decorative materials for the exterior walls must meet a certain fire rating. Due to the advantages of light weight, corrosion resistance, and heat insulation, aluminum-plastic panels have been rapidly developed as a building decoration material. In order to meet the requirements of flame retardancy, low-smoke and halogen-free flame-retardant aluminum-plastic panels have also been developed. For example, patent CN02113998. The core material of the flammable polyolefin aluminum composite panel. This kind of material is the main product of flame-retardant aluminum-plastic panel in the ...
