Abstract
The glass fibre reinforced plastic heat-insulating plate material is mainly formed from glass fibre reinforced plastic plate and polyurethane hard foam, and its production method adopts the prodction process of glass fibre reinforced plastic plate, including proportioning polyurethane hard foam and injection moulding. Said invented production method is simple and easy to implement, and its cost is low, and its finished product features good sound-insulating effect, high heat-insulating property, large strength and light weight.
Description
The present invention relates to the sheet material technical field, particularly a kind of heat preservation plate material and manufacture method made from fiberglass thereof.
Existing various sheet material can't be unified on adiabatic heat-insulation and intensity, the sheet material that adiabatic heat insulating effect is good, and intensity difference, strong high sheet material, adiabatic heat insulating effect is poor.In a lot of fields, often need existing intensity, utmost point material that again can adiabatic heat-insulation, and require in light weight, easy carrying, easy-formation, and general sheet material can not satisfy the demands.

The object of the present invention is achieved like this:
The present invention is hard bubbled by glass epoxy and polyurethane and is formed.
Manufacture process of the present invention is: the making of glass epoxy, the polyurethane metering of hard bubbling, injection molding, moulding.
Concrete manufacturing process of the present invention is as follows:
A. the making of glass epoxy:
Select 33#, 34#, 38# gel coat or food-grade gel coat for use, density is 30-50g/m
2Glass mat make surfacing, selecting specification for use is that the middle alkali glass cloth of 0.4mm, 0.2mm is made reinforcing material, select for use the saturated alkyd resin of 196# to make stock, select for use peroxide initiator and cobalt class promoter to be cured, at normal temperatures and pressures, make glass epoxy, and the edge stretches, single face is bright and clean;
B. the polyurethane metering of hard bubbling
Select PAPI isocyanate compound and polyether polyols for use, by metering in 1: 1; The color and luster of the different poly-sour fat compound of PAPI is a dark brown, and little have fragranced, NCO content 31.8%, viscosity (10
-3Handkerchief. second/25 ℃) be 200, hydrolysis chlorine 0.1%, total chlorine 0.5%, freezing point is less than-20 ℃; The molecular weight of polyether polyols is below 1300, and hydroxyl value is that degree of functionality is between 3-8 below 700;
C. casting
Be on the metal die of 3cm with pin fixing metal panel at thickness, two blocks of glass epoxies are put into metal die, there is the demoulding wax metal die inboard, form the abdominal cavity in the middle of two blocks of glass epoxies, the smooth surface of glass epoxy is respectively towards metal die inner face place, behind matched moulds, bore a hole on the corresponding glass epoxy of metal tool material hole, then, PAPI isocyanate compound and polyether polyols stir evenly mixed in metal bucket rapidly, in one minute, inject die cavity with funnel, when treating that material hole has minority bubble material to occur, with movable stopper material hole is clogged, after 2-3 hour, die sinking gets glass fiber reinforced plastics insulating board.
The technical indicator of glass fiber reinforced plastics insulating board of the present invention is as follows:
Density 〉=100Kg/m
