Description
Technical Field
The invention belongs to the technical field of composite materials, and particularly relates to a fireproof smoke-suppressing modified anti-inflammation cloth for a building and a preparation method thereof.
Background
The anti-inflammation cloth for the building is a safety protection net material widely used in construction sites and engineering sites, is used for preventing objects from falling from the high altitude, plays a role in safety protection, has fireproof and flame retardant properties, and can prevent fire caused by electric welding, smoke and fire and short circuit of electric wires in the construction process.
The anti-inflammation fabric for building is made up by using high-strength polyester yarn to make warp-knitted net, impregnating it with PVC resin, high-temp. heating, high-pressure punching, cooling, making mesh fabric, and making it into various products with different sizes by means of edge-covering and fastening processes. The anti-inflammatory cloth for the building is generally pursued to have good flame retardant property, high strength, durability, light weight, attractive appearance and easy cleaning.
The national standard GB8624-2012 classifies the combustion performance of the building material into the following grades: a level: incombustible building material: a material that burns little. B1 level: flame-retardant building materials: the flame-retardant material has better flame-retardant effect. It is difficult to ignite in the air when meeting open fire or under the action of high temperature, is difficult to spread quickly, and stops burning immediately after the fire source is removed. B2 level: combustible building materials: the combustible material has a certain flame-retardant effect. When meeting open fire in the air or burning under the action of high temperature, the fire can spread easily, such as wood columns, wood roof trusses, wood beams, wood stairs and the like. B3, level: flammable building materials: has no flame retardant effect, is extremely easy to burn and has great fire hazard.
In order to prevent fire caused by electric welding, fire and fire, and short circuit of electric wires during construction, a proper amount of flame retardant is usually added into the PVC resin of the anti-inflammation cloth, and the currently used flame retardants mainly comprise antimony compounds, such as antimony trioxide, antimonate and the like. The flame retardant mechanism of antimony trioxide is that when the anti-inflammation cloth is burnt, antimony compounds and polyvinyl chloride generate antimony oxychloride and antimony trichloride, which can capture free radicals and isolate air, so that polyvinyl chloride is promoted to carbonize to play a flame retardant role, and the flame retardant role is usually carried out in a gas phase. However, although antimony compounds have excellent flame retardant effect, a large amount of harmful smoke is inevitably generated in the combustion process of polyvinyl chloride (PVC), which brings harm to human beings and ecological environment, so that an appropriate amount of smoke suppressant is added while antimonide is added to reduce the amount of smoke generated.
Molybdenum compounds are known to be flame retardant and smoke suppressant, and in the early stage of thermal decomposition of PVC, molybdenum compounds promote intermolecular crosslinking reaction to form carbides which cover the surface of the polymer to thereby exert flame retardant and smoke suppressant effects. The synergistic flame-retarding and smoke-inhibiting effect can be displayed by adding a proper amount of molybdenum compound and other flame retardants into the PVC resin.
However, the composite use of the antimony trioxide and the molybdenum compound has the disadvantages that the flame retardant effect is poorer and the smoke suppression effect is not ideal under the lower use amount compared with the same use amount of the antimony trioxide, and the cost is increased, the strength of the anti-inflammation cloth is reduced and the weight of the anti-inflammation cloth per unit area is increased under the higher use amount although the flame retardant effect and the smoke suppression effect are good.
The polymer material filled with the inorganic nano powder can improve the performances of the polymer material such as rigidity, hardness, wear resistance and the like, and the strength and toughness of the polymer material can be reduced while the performances are enhanced by the common polymer material filled with the inorganic powder filler. The nanometer inorganic powder has small grain size and large specific surface area, so that the nanometer inorganic powder has strong binding force with a matrix in the polymer composite material, thereby not only improving the rigidity and the hardness of the material, but also playing a toughening role. The nano particles are uniformly added into the resin, so that the aim of comprehensively improving and enhancing the resin performance (improving the strength and the elongation, improving the wear resistance, improving the surface roughness of the material and improving the ageing resistance) can be fulfilled.
Known as nano CaCO 3 The nano-composite with the PVC resin can obtain the mechanical properties or heat resistance with high hardness, high modulus, high scratch resistance and the likeThe nano inorganic powder is filled with polymer materials. However, the use of a large amount of nano-powder will further increase the production cost of the product.
