Abstract
The invention provides a vacuum perfusion infusion forming technique used for a speedboat, which comprises the steps of: cleaning, waxing and polishing a speedboat shell die at first, coating surface paint with the thickness of 0.6-1mm, then reinforcing a basic layer and coating glass fiber reinforced plastic with the coating thickness of 2-3mm, manually laminating a cloth felt on the coating, and then covering a diversion net, a demoulding cloth and a plastic cement cloth on the felt in sequence, respectively connecting one ends of a vacuumizing pipe and a resin diversion pipe on the diversion net and arranging the other ends outside, injecting resin after vacuumizing, and demoulding after forming. The vacuum perfusion infusion forming technique used for the speedboat has the advantages of reducing the weight of the original layer by 30 percent, reducing the emission of styrene by 90 percent, reducing the cycle time by 50 percent and reducing the labor cost by 30 percent, greatly improves the flow speed and has stable product performance.
Description
Technical field
The present invention relates to a kind of vacuum infusion molding technology, be used for the shell shop layer of speedboat, belong to the vacuum infusion molding technology field of speedboat shell shop layer.
Background technology
The traditional handicraft of speedboat shell shop layer is to clean shell mould and waxing polishing earlier, and the spray gel coat is spread 18 layers of fiberglass with the method that hand is stuck with paste again on the shell mould subsequently, has so just finished Ship Structure.Its weight of shop layer of finishing by this method can reach about 10 tons, the very big ship's speed that must limit speedboat.Simultaneously, owing to be hand pasting forming, so labour intensity is big, the technology that product quality too relies on each operating personnel causes stability not high.And in this production process, cinnamic emission is big, and labour health condition is poor.
Summary of the invention
The purpose of this invention is to provide a kind of stable vacuum infusion molding technology of weight while properties of product that can reduce the shop layer.
In order to achieve the above object, technical scheme of the present invention has provided a kind of priming by vacuum infusion forming technology that is used for speedboat, the steps include:
Step 1, cleaning shell mould and waxing polishing;
Step 2, be the surface lacquer of 0.6～1mm, it is characterized in that with the shell die surface spray thickness of no pressure-type spray coating device behind waxing polishing,
Step 3, the shell mould surface spraying resin and the mixture of glass fibers that obtain in step 2 are earlier carried out basic unit and are reinforced, and coating thickness is 2～3mm, and with the coating of no pressure-type spray coating device spraying fiberglass, coating thickness is 2～3mm again;
Step 4, craft lamination Fabric felt in coating, the gross thickness of felt is 10～20mm;
Step 5, cover water conservancy diversion net, release cloth and plastic cloth successively on felt, it is online that an end that vacuumizes conduit and resin mozzle is connected to water conservancy diversion, and the other end places the outside;
Step 6, be evacuated down to negative 86MPa with the negative pressure vaccum-pumping equipment, open the resin mozzle subsequently resin is injected between felt and the release cloth by vacuumizing conduit, make resin can before and after infiltration encase felt;
Step 7, make more than 2 hours and slough water conservancy diversion net, release cloth, plastic cloth behind the resin cooling forming, vacuumize conduit and resin mozzle leaving standstill under the normal temperature negative pressure, just finished Ship Structure.
The present invention combines all advantages and the various advantages of mold closing technology aspect construction, performance, health and safety of sandwich composite.The present invention adopts vaccum-pumping equipment, utilizes negative atmospheric pressure to enter the resin osmosis at normal temperatures, and solidifying and setting makes resin and fiberglass combine closely at short notice.
Advantage of the present invention is: the weight of original shop layer has been reduced 30%, reduced simultaneously by 90% styrene emission in process of production, reduce by 50% cycle time and reduce by 30% labor cost, can directly use existing mould in process of production; Compare with existing method, method of the present invention can greatly must improve flow velocity, and the technology that product quality is no longer dependent on each operating personnel makes properties of product stable.
