Description

A kind of compound formpiston of yacht housing

Technical field

The utility model relates to a kind of compound formpiston, specifically refers to the compound formpiston for a kind of yacht housing of the formpiston of making yacht compound resin casing products.

Background technology

The compound resin shell of yacht is to form the shell wall of compound resin on the yacht housing formpiston of hull shape face through coating, laminated multilayer resin bed and glass casing ply, then makes through cure and demold; The yacht housing formpiston of prior art is wooden formpiston, rough surface due to wooden formpiston, and the wooden variation that is subject to water content and cracking or distortion, make the surface quality of the compound resin yacht shell of making of wooden formpiston bad, the service life of wooden formpiston is short, need to constantly upgrade formpiston, causes the poor quality of yacht compound resin casing products, cost is high, and efficient is low.Therefore, prior art exists poor quality, the life-span is short, cost is high problems and shortcomings.

Summary of the invention

Problems and shortcomings for above-mentioned prior art existence, the utility model adopts the compound formpiston by basic steelframe, plank layer, froth bed, frp layer, wooden layer of generation, gel coating resin stepped construction, and supporting technical scheme with the processing technology thereof method, a kind of compound formpiston of yacht housing is provided, be intended to make yacht housing formpiston avoid the drawback of wooden formpiston by composite construction, reach and improve quality of item, extend formpiston service life, reduce the purpose of the integrated cost of formpiston and goods.

The purpose of this utility model is achieved in that a kind of compound formpiston of yacht housing, comprise compound formpiston and preparation method thereof, wherein: described compound formpiston is from bottom to top from inside to outside, to be made of basic steelframe, plank layer, froth bed, frp layer, wooden layer of generation, gel coating resin;

Described basic steelframe is for being the truss of hull bottom shape above being made of the angle steel welding;

Described plank layer is the China fir layer;

Described froth bed is the RPUF layer;

Described frp layer is for to add by epoxy resin the fiber glass epoxy layer that the glass fibre cord consists of;

Described generation the wood layer for the epoxy that solidify to form by epoxy resin pasty state mud for the wood layer;

Described gel coating resin is the unsaturated polyester resin layer;

Described preparation method is:

Step 1, with the China fir plate paste be fixedly connected on basic steelframe above, with numerical control machining center, the outer surface machining of China fir plate is become the hull shape of back-off, obtain thus the plank layer of ship shape on basic steelframe;

Step 2, paste one deck RPUF with neoprene on the outer surface of plank layer, with numerical control machining center, the outer surface machining of RPUF is become the hull shape layer of the back-off of uniform thickness, obtain thus the froth bed of one deck uniform thickness ship shape at the outer surface of plank layer;

Step 3, apply on the outer surface of froth bed and add by epoxy resin the fiber glass epoxy layer that the glass fibre cord consists of, room temperature was solidified in standing 12 hours, and the outer surface at froth bed obtains one deck frp layer thus;

Step 4, coating thickness is the epoxy resin pasty state mud layer of 8～15 millimeters on the outer surface of frp layer, room temperature was solidified in standing 24 hours, afterwards, with numerical control machining center, the outer surface machining of epoxy resin pasty state mud cured layer being become thickness is the hull shape layer of the back-off of 5 millimeters, and the outer surface at frp layer obtains one deck for the wood layer thus;

Step 5, evenly coating thickness is the unsaturated polyester resin layer of 0.5～1 millimeter on the outer surface of generation wood layer, and room temperature was solidified in standing 24 hours, thus generation wood layer 5 outer surface obtain one deck gel coating resin.

Above-mentioned, the utility model adopts the compound formpiston by basic steelframe, plank layer, froth bed, frp layer, wooden layer of generation, gel coating resin stepped construction, and supporting technical scheme with the processing technology thereof method, overcome prior art and had poor quality, the life-span is short, cost is high problems and shortcomings, the compound formpiston of a kind of yacht housing that provides, make yacht housing formpiston avoid the drawback of wooden formpiston by composite construction, reached and improved quality of item, extend formpiston service life, reduce the purpose of the integrated cost of formpiston and goods.
