Problems solved by technology

Phenolic foam also has serious disadvantages: unsatisfactory physical properties, poor overall cohesion, and extremely low compressive and flexural resistance; phenolic itself is very brittle, easy to pulverize, and is not suitable for exterior walls, and needs to be reprocessed and constructed. The loss is relatively large
[0004] CN106496540A discloses a kind of synthetic method for the phenolic polyether polyol of flame-retardant type polyurethane rigid foam plastics, and is applied in polyurethane rigid foam, can improve the oxygen index of foam, make it have flame-retardant performance, this technology Introducing phenolic structure into polyether polyol, and then using it in polyurethane products, the preparation process is cumbersome, the process is complicated, the technical requirements are high, and the actual promotion is difficult; CN105218782B discloses a kind of expandable graphite modified high flame-retardant polyurethane rigid foam The preparation method of this technology improves the oxygen index of rigid polyurethane foam by compounding graphite, etc., and the combustion performance can reach the non-combustible level. This technology improves the flame retardancy of polyurethane products by compounding graphite, but the expanded graphite is a solid particle. It will affect the fluidity of the product and reduce other properties of the product, and there are many limitations
[0005] Phenolic thermal insulation foam has been widely used in the field of industrial building thermal insulation, and the product has excellent flame retardant performance and low price. Flame retardants improve the flame retardancy of products, but the cost is higher

Description

technical field [0001] The invention relates to a pentane-type multi-component highly flame-retardant polyurethane composite phenolic continuous board composite material and a preparation method thereof, belonging to the technical field of polyurethane composite modification. Background technique [0002] Traditional polyurethane rigid foam has the advantages of light weight, low density, high strength, low thermal conductivity, etc., but there are many deficiencies in the existing technical conditions, such as high price of polyurethane foam, flammable plastic, poor heat resistance, and it will produce toxic gases after burning. Smog, which seriously restricts the application and widespread promotion of polyurethane thermal insulation materials, thus more and more researchers have targeted the development of polyurethane thermal insulation materials with strong flame retardant properties. With the pressure of the environmental protection situation, the foaming agent replace...
