4) carry out surface finish process with sand paper, the texture along decoration panel is polished, and forbids, by texture laterally polishing, to ensure door epidermis face impulse-free robustness, ashless scar, and ash cleaned out;
5) wiping look process: after brushing one times wiping stain with wool brush on plate face, embrocate evenly with rag along grain direction, control lacquer painting is even, no sag;
6) the clear priming paint of PU is sprayed; Spraying evenly, controls the defect of paint vehicle without particle, no sag;
7) repair; After primed surface solidification drying, carry out pinprick and shrink trace reparation;
8) polish; First adopt 400 order sand paper to carry out uniform grinding, then carry out fine grinding with 600 order sand paper, ensure the ashless scar in door epidermis face, impulse-free robustness, free of pinholes, without bright spot, free from dust, the texture along decoration panel is polished;
9) finish paint spraying, controls the defect of paint film without particle, no sag, nothing atomization.
6. the making method of the luxurious imitative wooden model pressure gate of a kind of advanced composite material according to claim 4, is characterized in that: described door dermatotome (1) adopts die press technology for forming compression moulding by using SMC sheet molding compound, and concrete steps are as follows:
The releasing agent of 1-3 part is added in the unsaturated polyester resin of 20-30 part, with high speed dispersor with the speed uniform stirring 2min of 1200r/min, then successively by filler 30-40 part, shrinking agent 1-2 part, solidifying agent 1-3 part, look sticks with paste 2-5 part, thickening material 0.5-2 part adds, this process high speed dispersion machine should continue at the uniform velocity to stir, and remain on more than 1000r/min, after starting material have all added, continue at the uniform velocity to stir 5-8min, to prepare resin paste places for subsequent use, SMC units for sheet material starts, reinforcing glass fiber 25-35 part is adjusted to 10mm specification, by reinforcing glass fiber online broken and with resin paste Homogeneous phase mixing after carry out stone roller conjunction and soak into, transfer rate controls within 0.5m/min, and control resin paste flow well, travelling belt is kept at the uniform velocity to transmit, milling roller is adjusted to 1.2mm gap, ensure to grind the compound gauge control after closing within 1.2mm, and by coated for material two sides polyester film, winding rolling or folding piling become case, can use after warm slaking 48h under 50 DEG C of conditions.
7. the making method of the luxurious imitative wooden model pressure gate of a kind of advanced composite material according to claim 6, is characterized in that: in described SMC sheet molding compound die press technology for forming process, material cured temperature is lower than 145 DEG C, and forming pressure is 6Mpa/m
2below, curing speed is lower than 50s/mm.
