Abstract
The invention discloses a solid buoyancy material. The solid buoyancy material consists of the following components in parts by weight: 50 parts of brominated epoxy resin, 50 parts of novolacepoxy, 100-120 parts of curing agent, 0.2-0.4 part of accelerator, 30-90 parts of hollow glass beads, 1-5 parts of coupling agent, 5-8 parts of fire retardant and 10-25 parts of flexibilizer. According to the solid buoyancy material, compound epoxy resin combined with the curing agent is used as a matrix resin system; the hollow glass beads with high intensity and low density are used as light filler; the fire retardant and the flexibilizer with high efficiency and low density are added and the densities of the fire retardant and the flexibilizer are controlled to be 0.42-0.45g/cm<3>; meanwhile, by adding the fire retardant, the flame-retardant performance of the solid buoyancy material is improved, the velocity of the compound epoxy resin can be reduced, the flowability of the compound epoxy resin is improved and the density of the material is reduced; by adding the flexibilizer, the combinability of the hollow glass beads and an epoxy resin matrix can be improved; the compressive strength of the obtained material reaches Im30K, 205MPa.
Description
Technical field
The present invention relates to a kind of solid buoyancy material, be specifically related to a kind of fire-retardant anti-impact high tenacity solid buoyancy material.
Background technology
Solid buoyancy material (Solid buoyancy material), is by inorganic light weight packing material, is filled in organic polymer material the solid compounds obtaining through physical-chemical reaction.From macroscopic view, this material is the polymer-based carbon solid material of a kind of low density, high strength, few water suction, has the low (0.20～0.7g/cm of density
3), water-intake rate low (being not more than 3%), physical strength high (compressive strength 1～100MPa), corrosion-resistant, can carry out the features such as secondary mechanical processing, meet different application requiring under water.
But solid buoyancy material is easy to be collided and impact after producing in the process of carrying, use, and therefore the erosion-resisting characteristics of material need to improve.Simultaneously, along with China's expanding economy, the continuous progress of ocean science, oceanology level, the frequency of the activities such as ocean scientific research, investigation, measurement increases substantially, solid buoyancy material is adopted in a large number, and the fire hazard that thereupon carries the place such as boats and ships and warehouse of storage solid buoyancy material also increases greatly.The horizontal fire preventing of depending on science and technology, reduces the loss of fire, and one of important measure is exactly to adopt the solid buoyancy material with flame-retarding characteristic.The use of fire-retardant solid buoyancy material is for effectively putting out initial fire disaster and reducing fire losses and created favourable condition.
Summary of the invention
For addressing the above problem, the invention discloses following technical scheme:
A kind of solid buoyancy material, is made up of by weight following component:
50 parts of brominated epoxy resins, 50 parts of novolac epoxys, solidifying agent 100-120 part, promotor 0.2-0.4 part, hollow glass micropearl 30-90 part, coupling agent 1-5 part; Fire retardant 5-8 part, toughner 10-25 part.
Further, described solidifying agent is that diaminodiphenylmethane or this addition polyamine curing agent of modified multicomponent amine hardener 593 and Manny T-31 mix with mass ratio 1:2.
Further, described promotor is dimethyl benzylamine, 2,4,6-tri-(dimethyl amine ylmethyl) phenol or 2-ethyl-4-methylimidazole.
Further, the median size of described hollow glass micropearl is 20-50 μ m, and ultimate compression strength is greater than 25MPa, and density range is 0.13-0.5g/cm
3.
Further, described coupling agent is Silane coupling agent KH550.
Further, described fire retardant adopts heterocyclic phosphorous-nitrogen system bittern-free fire retardant.
Further, described fire retardant adopts FR-FMV302.
Further, described toughner adopts POE8200.
Positively effect of the present invention is: adopt composite epoxy resin in conjunction with solidifying agent as basic resin system, take the hollow glass micropearl of high-strength low-density as light filler, add efficient low-density fire retardant and toughner, its density is controlled to 0.42-0.45g/cm
3simultaneously fire retardant add the flame retardant properties that has not only increased solid buoyancy material, also can reduce the viscosity of composite epoxy resin, improve its mobility, reduce density of material, adding of toughner can improve the associativity between glass microballon and epoxy resin-base, and the ultimate compression strength of resulting materials reaches Im30K, 205MPa.
