It 2-5 parts of fourth rouge, pours into container and is mixed, stirred evenly, it is spare；
B, it makes bed die: being laid with three layers of fiber filament in die surface, be laid with before fiber filament every time, uniformly brush a gypsum
Slurry can demould after standing 30-50min；
C, the bed die made bed die baking, brushing: is carried out first time baking, baking time 15- at 130-170 DEG C
20min；The raw material slurry that one layer of step A is mixed up uniformly is brushed on bed die surface baked for the first time, with each position in bed die surface
Being coated onto is advisable；Bed die carries out secondary baking after brushing, baking temperature is 400-500 DEG C, baking time 8-15min；It is secondary
Secondary brushing is carried out after baking, secondary brushing is with a thickness of 1.5-2.5mm；It repeats baking, brush 3-4 times；Last baking temperature
Degree is 250-350 DEG C, baking time 8-15min；
D, it makes glass fibre reinforced plastics casing: smearing stabilizer on the bed die after last baking, be then laid with layer of glass cloth, weight
Overcoating is smeared stabilizer, is laid with glass fabric 4-5 times, obtains glass fibre reinforced plastics casing, the high-temperature resin mold taken off is put on the shell,
To obtain the final product.
Further, in the step B, calcium plaster is mixed by gypsum and water according to the weight ratio of 2:1.
Further, in the step B, bed die is with a thickness of 2-3cm.
Further, the stabilizer is obtained by mixing by 191 resins, p-hydroxybenzenyl sulfonate and tetramethyl thiourea.
The invention has the benefit that
The resistance to drawing of the mold that the present invention makes, durable, good toughness, the product poured out is smooth, bright, resin die long service life,
Up to 3 years or more.
