Description
Technical field
The present invention relates to a kind of FRP plate and preparation method thereof, particularly a kind of Filled With Hollow Bead FRP plate and preparation method thereof.
Background technology
FRP plate is commonly called as glass epoxy, is a kind of matrix material, forms primarily of two sections of material.A part is called strongthener, plays skeleton function in the composite, mainly glass fibre; Another part is called body material, plays cohesive action in the composite, mainly various types of resins, comprises epoxy resin, unsaturated polyester resin etc.Glass fibre can strengthen the mechanical property of FRP plate, therefore the resistance to compression of FRP flat board and bend resistance performance outstanding, in addition FRP plate is from heavy and light, smooth surface, easy to clean, ageing-resistant, corrosion-resistant, is widely used among the engineerings such as architectural lighting roof, decorative curtain wall and exterior wall, superior automobile, refrigerated vehicle carriage plate and purification, medical treatment, food sanitation.
Along with energy dilemma is on the rise; the concept of energy-conservation especially building energy conservation is rooted in the hearts of the people; in building trade, people have taken various measures to strengthen the heat preservation and insulation of architectural exterior-protecting construction, improve the utilising efficiency of building to the energy, reduce the energy consumption of buildings.But from the situation of FRP plate in the market, FRP plate product for lighting roof and decorative curtain wall, these purposes of exterior wall does not go to improve its heat insulating ability especially, make to adopt FRP plate not have the effect of building energy conservation as the architectural exterior-protecting construction of the forms such as lighting roof, curtain wall, exterior wall, do not meet the development trend of building energy conservation.
Hollow glass micropearl is a kind of glass microballon through special processing treatment, and its principal feature is that density is less compared with glass microballon, and thermal conductivity is lower.Hollow glass micropearl is a kind of micron order novel light material grown up in twentieth century five sixties, and its main component is borosilicate, and general particle diameter is 5 ~ 250 μm, and wall thickness is 2 ~ 50 μm; Hollow glass micropearl has that ultimate compression strength is high, fusing point is high, resistivity is high, thermal conductivity coefficient and the feature such as Thermal Contraction Coefficient is little, there is obvious weight reduction and sound-insulating effect, make goods have good freedom from cracking performance and cycling processability, be widely used in fields such as the matrix materials such as glass reinforced plastic, artificial marble, artificial agate and petroleum industry, aerospace, Novel high-speed train, automobile steamer, thermal insulating coatings.
At present, study and prepare Filled With Hollow Bead FRP plate, not yet having report at present to make the work of its architectural exterior-protecting construction that can meet as heat insulating in building energy conservation.
Summary of the invention
The invention discloses a kind of Filled With Hollow Bead FRP plate and preparation method thereof, this FRP plate compares traditional F RP plate, has the advantage that quality is light, thermal and insulating performance is good.
For achieving the above object, the technical scheme that the present invention takes is: a kind of Filled With Hollow Bead FRP plate, and raw material is by 55 ~ 75wt% resin, 15 ~ 35wt% glass fibre, 0.2 ~ 1.0wt% promotor, 0.5 ~ 1.5wt% solidifying agent, 3 ~ 15wt% hollow glass micropearl forms.
Described resin is unsaturated polyester resin.
The diameter of described glass fibre is 0.05 ~ 0.3mm, and length is 30 ~ 50mm.
Described solidifying agent is methylethylketone.
Described promotor is cobalt water.
Described hollow glass micropearl, its outside diameter is 10 ~ 50 μm, and interior diameter is 8 ~ 45 μm.
The preparation method of above-mentioned a kind of Filled With Hollow Bead FRP plate, mainly includes following steps:
(1) weigh: weigh described resin, glass fibre, promotor, solidifying agent and hollow glass micropearl for subsequent use;
(2) stir: by load weighted described resin injection reaction vessel, and stir with agitator, and in reaction vessel, add hollow glass micropearl, glass fibre successively successively, continue to stir;
(3) react: while keeping stirring, in reaction vessel, first inject promotor, reinject solidifying agent, treats that it reacts;
(4) shaping: the reaction mixture in reaction vessel to be poured into previously prepd board slot shape mould, leave standstill shaping;
(5) demoulding: the FRP plate demoulding complete for board slot shape die for molding is taken out.
The churning time of described step (2) is 10 ~ 30min.
The reaction times that described step (3) is injected after promotor is 5 ~ 10min, and the reaction times of injecting after solidifying agent is 5 ~ 10min.
In above-mentioned preparation method, the stir speed (S.S.) of described agitator is 200 ~ 400 r/min.
The present invention utilizes the hollow glass micropearl that density is little, thermal conductivity is low to add among the manufacture raw material of FRP plate, Filled With Hollow Bead FRP plate is obtained by reacting shaping, the density of FRP plate can be reduced on the one hand further, thus reduce the deadweight of FRP plate, thus be convenient to transport, installation and use; On the other hand, the hollow glass micropearl of lower thermal conductivity can reduce the thermal conductivity of FRP plate effectively further, thus improves its thermal and insulating performance, makes its use as a kind of energy-saving building space enclosing structure material become possibility; In addition tiny hollow glass micropearl helps the mechanical property strengthening FRP plate.
The production cost of this FRP plate increases (2 ~ 10%) to some extent with the raising of the addition of hollow glass micropearl, but after interpolation hollow glass micropearl, the thermal conductivity of FRP plate can reduce that the thermal conductivity of 10 ~ 35%(Filled With Hollow Bead FRP plate is after tested minimum reaches 0.186 W/m
-1k
-1, relatively do not add hollow glass micropearl sample and reduce 35%), therefore the present invention is feasible economically.Meanwhile, preparation is simple for the Filled With Hollow Bead FRP plate in the present invention, improves existing FRP plate production technique, can realize the scale operation manufacture of this Filled With Hollow Bead FRP plate completely by limited.
