In Fig. 1: bathtub casing 1; Fiber adhesive linkage 2; Foamed polyurethane material layer 3; Fiber adhesive linkage 4; Bathtub shell 5.
In Fig. 2: mold 6; Bed die 7.
The specific embodiment
In conjunction with Fig. 1, composite bathtub mainly is made up of bathtub casing 1, bathtub shell 5 and the foamed polyurethane material layer 3 as packed layer that is in 5 of bathtub casing 1, bathtub shell, the panel of moulding of its bathtub casing 1 and bathtub shell 5 utilizations is acrylic sheet material (PMMA/FRP), is provided with fiber adhesive linkage 2,4 as the acrylic sheet material and 3 of the foamed polyurethane material layers of bathtub casing 1 and bathtub shell 5.Fiber adhesive linkage 2,4 can be the glass fibre adhesive linkage, also can be the string adhesive linkage.
The manufacture craft of composite bathtub mainly comprises: the making flow process of mould, the setting-out flow process of bathtub casing 1 and bathtub shell 5, the making flow process of bathtub casing 1, the making flow process of bathtub shell 5, bathtub moulding flow process.
In the making flow process of mould, adopt the shape of fire resistant resin material according to bathtub, be made into the mould of bathtub casing 1 and bathtub shell 5, the mould of bathtub shell 5 is mold 6 and bed die 7 (with reference to Fig. 2), mold 6 has the shape of bathtub shell 5, bed die 7 does not have the bottom surface, can allow the bottom of mold 6 pass.
In the setting-out flow process of bathtub casing 1, bathtub shell 5, according to the shape of bathtub acrylic sheet material is carried out setting-out and cut out, make the acrylic sheet material that meets bathtub casing 1 and bathtub shell 5 processing specifications.
In the making flow process of bathtub casing 1, the acrylic sheet material that will meet bathtub casing 1 processing specification is put into baking oven, under the condition of 150-180 degree celsius temperature, heats 5-10 minute; Acrylic sheet material after will heating is again put on bathtub casing 1 mould limit is pressed, the placement of acrylic sheet material will make the one side with rete make progress, simultaneously to the mould extracting vacuum, to the vacuum (vacuum meter reading) of mould extracting vacuum be-0.06~-0.09M Pascal, and pressurize 2 minutes, the stretching action of the acrylic sheet material after utilizing atmospheric pressure to heating, make bathtub casing 1 moulding, after bathtub casing 1 moulding finishes, air-cooled 3-10 minute, the demoulding; Like this, can keep the inner face of bathtub casing 1 that fineness is preferably arranged through processing.
In the making flow process of bathtub shell 5, the acrylic sheet material that will meet bathtub shell 5 processing specifications is put into baking oven, under the condition of 150-180 degree celsius temperature, heated 5-10 minute, acrylic sheet material after the heating is put on the bed die 7 of bathtub shell 5, and the placement of acrylic sheet material will make to have one of rete and faces down, and the mold 6 of bathtub shell 5 is fixed on the press, by the moulding that presses down of mold 6, air-cooled 3-10 minute, the demoulding; Like this, can keep the outside of bathtub shell 5 that fineness is preferably arranged through processing.In the moulding flow process of bathtub shell 5, press employing pressure is 16 tons fly press.The making flow process of bathtub shell 5 also can adopt the identical making flow process of bathtub casing 1.
Heating as the acrylic sheet material of bathtub casing 1 and bathtub shell 5 can be controlled at temperature 150 degrees centigrade, is controlled at heat time heating time 8-10 minute.Heating as the acrylic sheet material of bathtub casing 1 and bathtub shell 5 can be controlled at temperature 160 degrees centigrade, is controlled at heat time heating time 7-9 minute.Heating as the acrylic sheet material of bathtub casing 1 and bathtub shell 5 can be controlled at temperature 170 degrees centigrade, is controlled at heat time heating time 6-7 minute.As the heating of the acrylic sheet material of bathtub casing 1 and bathtub shell 5, optimum temperature can be controlled at 180 degrees centigrade, is controlled at heat time heating time 5-6 minute.For the heating as the acrylic sheet material of bathtub casing 1 and bathtub shell 5, in limiting the control temperature range, the temperature of control is high more, needs the time of heating then short more.
In bathtub moulding flow process, lateral surface to bathtub casing 1 lays fiber adhesive linkage 2, corresponding with bathtub casing 1, inner face to bathtub shell 5 lays fiber adhesive linkage 4 simultaneously, again bathtub casing 1 and bathtub shell 5 are integrated, and foam in the cavity with polyurethane liquid injection bathtub casing 1 and 5 formation of bathtub shell, form foamed polyurethane material layer 3.Laying of fiber adhesive linkage 2,4, string or glass fibre can be laid in and lay on the bathtub casing 1 and bathtub shell 5 of fiber adhesive linkage 2,4, the spraying liquid resin, fiber is bonded on bathtub casing 1 and the bathtub shell 5, effect is to make foamed polyurethane material layer 3 keep further strengthening the shock resistance of bathtub as firm connection the between the acrylic sheet material of bathtub casing 1 and bathtub shell 5.
In to bathtub casing 1 mould extracting vacuum, use the two poles of the earth water ring vacuum pump-atmospheric pump unit, the limiting pressure of this unit extracting vacuum can reach-0.094MPa; The vacuum meter reading that uses is negative value, and it establishes normal pressure is zero, and the vacuum that the big more expression of the absolute value of negative value need be extracted is big more.
In the moulding flow process of bathtub casing 1, bathtub shell 5, the surface after making one side that acrylic sheet material has a rete as bathtub machine-shaping is to keep the fineness on bathtub surface.Press the bathtub that present embodiment is made, can routinely discharge outlet and gap be set.
Adopt present embodiment, the moulding panel and can also mould the sheet material of system of utilization for ABS sheet material and other.
