Abstract
The invention belongs to the technical field of new materials, and discloses a composite cross-linkable ceramic low-smoke halogen-free heat-insulating polyolefin material, the specific raw material formula comprises a base material, an inorganic flame retardant, an inorganic ceramic forming composite additive, a composite cross-linking agent, a lubricant, an antioxidant and a silane coupling agent, and the weight ratio of the silane coupling agent to the composite cross-linking agent is 100: (2-10). According to the invention, the compatibility of the base resin and the inorganic powder can be improved through a silane grafting technology on the base resin; through blending pretreatment of the powder, the compatibility of the powder can be improved; by mixing inorganic powder in different proportions, the ceramic forming effect is achieved in high-temperature combustion, the expansion rate of combustion residues is controlled to be 100 + / -5%, the expansion rate of 1: 1 can be kept, cracking or crushing of the combustion residues can be avoided, and the integrity of the combustion residues is kept; through composite crosslinking, the material has certain mechanical properties and heat resistance.
Description
technical field [0001] The invention belongs to the technical field of new materials, in particular to a composite cross-linkable ceramic low-smoke and halogen-free heat-insulating polyolefin material and a preparation method thereof. Background technique [0002] Vulcanized silicone rubber ceramic refractory material is mainly composed of silicone rubber and ceramic powder (a compound inorganic powder), which is mixed by equipment and extruded to granulate. Advantages: good refractory effect, environmental protection. Disadvantages: slow extrusion speed, slow vulcanization speed, can not be used as a sheath layer alone, can only be used as a refractory filler, because the material has no mechanical strength and the material is not scratch-resistant, and the price is expensive. [0003] Thermoplastic low-smoke halogen-free ceramic flame-retardant materials are mainly composed of polyolefin, metal hydroxide and other inorganic fillers, and are granulated through equipment fo...
