Embodiment 1

[0022] Embodiment 1: A kind of flame-retardant and fire-proof insulation material based on boron mud uses boron mud composite flame retardant, PE pellets and carbon dioxide gas as raw materials, and the quality of each composition raw material is respectively: Boron mud composite flame retardant: 7kg, PE Granules: 3kg, carbon dioxide: 0.3kg. Among them, the boron mud composite flame retardant is processed according to the following steps:

[0023] In the first step, 10 kg of 1250-mesh boron slime is calcined at 700°C, and then the solid-liquid mixture of calcined boron slime and water is reacted at 100°C for 1 hour, and dried at 105°C to obtain boron slime after physical and chemical treatment;

[0024] In the second step, the boron mud after the treatment obtained in the first step is mixed with 0.5kg800 purpose organic montmorillonite according to the mass portion ratio, and the high-speed mixer is used to stir and mix for 10 minutes to obtain a composite flame retardant;

Abstract

The invention discloses a flame-retarding heat-insulating material based on boric sludge and a preparation method of the flame-retarding heat-insulating material, belonging to the technical field of functional materials. The raw materials for preparing the flame-retarding heat-insulating material based on boric sludge comprise a boric sludge compound flame retardant, polymer granules and a foaming agent, wherein the boric sludge compound flame retardant is treated according to the following steps: (1) carrying out physicochemical treatment on boric sludge; (2) mixing the boric sludge subjected to physicochemical treatment in the step (1) with other flame retardants in proportion; and (3) adding a surfactant into a flame retardant mixture obtained in the step (2). The preparation method of the flame-retarding heat-insulating material based on boric sludge comprises the following steps of mixing the boric sludge compound flame retardant, the polymer granules and the foaming agent in proportion, melting, mixing, foaming and extruding to obtain the flame-retarding heat-insulating material based on boric sludge. The raw materials for preparing the boric sludge based flame-retarding heat-insulating material are easily available, the preparation method of the flame-retarding heat-insulating material based on boric sludge is suitable for large-scale production and cost is low.

Description

technical field [0001] The invention relates to a boron mud-based flame-retardant, fireproof and thermal insulation material and a preparation method thereof, belonging to the technical field of functional materials. Background technique [0002] As early as 2005, with the "Guo Ban Fa [2005] No. 33 Document" issued by the General Office of the State Council, various places have promoted energy-saving wall materials and energy-saving buildings, and promoted the development of wall insulation materials in the direction of light weight and energy saving. Polymer The use and development of thermal insulation materials have aroused the attention of the society. Polymer insulation materials have good insulation effect and light weight, but are easy to burn. In recent years, there have been many fire accidents in thermal insulation projects at home and abroad. The fire and flame retardant performance of polymer thermal insulation materials has attracted people's attention and has ...
