Abstract
The present invention relates to gel coating resin for ships, and particularly to gel coating resin with the functions of abrasion resistance and sea water corrosion resistance. The gel coating resin is a mixture, and base resin is compose of adipic acid type resin, neopentyl glycol type resin and m-phthalic type resin. Filling materials are composed of three abrasion-resistant filling materials of different granularity, namely emery, monocrystalline fused alumina and cast stone powder. A thixotropic agent and a stabilizing agent use active silica as a component thereof. The gel coating resin for ships has the characteristics of the common gel coating resin of good construction technology and good performance of comprehensive mechanical properties, and has the performances of sea water corrosion resistance and abrasion resistance, which are obviously superior to the common gel coating resin.
Description
The present invention relates to the gel coating resin that a kind of producing GFRP ply-board is used, particularly ship plank with gel coating resin for ship wear-resistant, the seawater corrosion resistance type.
Glass fiber reinforced plastics product generally adopts gel coating resin to form the outer surface layer ageing-resistant, corrosion-resistant, that color is attractive in appearance.Gel coating resin for ship also requires to have good wear resistance and resistance to corrosion seawater except the performance that above-mentioned general gel coating resin should possess.Present common gel coating resin still can satisfy the requirement of general glass fiber reinforced plastics product at aspects such as surface hardness, anti-day photooxidation aging property and construction technologies.But when being used for seagoing vessel, because lamina rara externa is subjected to high velocity flow in the seawater midium or long term and washes away and soak, wearing and tearing and foaming phenomenon take place very easily, influence the work-ing life of boats and ships.Someone proposed to have the gel coating resin prescription of sea water corrosion resistant and adopted and added filler increase wear resistance, sea water resistance soaks and the way of performance of flushing so as to improving, but this method is attended to one thing and lose sight of another, and makes gel coat surface layer mechanical property variation thereby poor effect.
The objective of the invention is at the deficiencies in the prior art, propose a kind of gel coating resin for ship.This gel coating resin is by the dissimilar resins and the filler that filter out, be optimized combination, make full use of its characteristic, make the performance advantage complementation of material therefor, obtain a kind ofly both having possessed that common gel coating resin is ageing-resistant, good mechanical performance, characteristics that construction technology is good, have the good wear resistance and the gel coating resin for ship of resislance to corrosion from sea water again.
The objective of the invention is by adopting following technical proposals to realize: by resin combination, a kind of mixture that fill composition and thixotropic agent constitute, its raw-material weight proportion scope is: adipic acid type unsaturated polyester resin 9-14%, neopentyl glycol type unsaturated polyester resin 10-24%, metaphenylene unsaturated polyester resin 61-70%, silicon carbide 0.30-0.65%, single alundum 1.6-3.0%, glass-cermic powder 0.85-1.25%, active silica 1.8-2.5%.
The raw-material weight proportioning of the screening formulation of preparation gel coating resin of the present invention is: adipic acid type unsaturated polyester resin 9%, neopentyl glycol type unsaturated polyester resin 24%, metaphenylene unsaturated polyester resin 61%, silicon carbide 0.65%, single alundum 2.45%, glass-cermic powder 0.9%, active silica 2.0%.
The size range of each filler component is in the formula for raw stock: silicon carbide 520-850 μ m, single alundum 90-150 μ m, glass-cermic powder 12-18 μ m.
The present invention compared with prior art has following advantage:
1, adopt various kinds of resin and filler combination objects system, both kept the advantageous property that common gel coating resin had, its wear resistance and resislance to corrosion from sea water are greatly improved again simultaneously.
2, manufacturing process is simple, and the material that is adopted is easy to obtain, and productive expense increases few.
3, still adopt original construction technology and laminate other parts that good consistency is arranged in the producing GFRP ply-board construction, its shelf lives is longer, has simplified working-yard gel coat preparation work.
The present invention is further elaborated below in conjunction with embodiment:
The present invention comprises: resin combination, fill composition, thixotropic agent.Resin combination is formed (its component sees Table one) by three kinds of dissimilar unsaturated polyester resins.Table one
The type of resin and prescription in the starting material
Unit: mol
Wherein: the effect of adipic acid type resin is to improve toughness and tension set; The effect of neopentyl glycol type resin provides good sea water corrosion resistant; The effect of metaphenylene resin is to have the good mechanical performance.Fill composition is formed by three kinds of filler combination, and each filler component should screen before use and through the silane type coupling agent treatment, its kind and granularity are not both in order to obtain favorable manufacturability energy and wear-resisting effect.Thixotropic agent adopts the active silica of vapor phase process preparation, and its effect provides thixotropy and plays function of stabilizer.
Production technique of the present invention: to adopt the production of 100L high speed shear formula mixing tank is example, and its type of raw materials and consumption see Table two.Table two
