Description
Technical field
The present invention relates to a kind of compositions, and in particular to the gel coat for wind electricity blade protection.
Background technique
Wind turbine blade of country's external power greater than 1MW generally uses conventional airless spraying or the poly- ammonia of roller coating outside mould at present
The technique of ester coating increases protective coating to epoxy matrix.This paint coatings, basic working procedure are as follows:
1, the matrix liquid perfusion resin infusion of blade demoulds after being solidified into blade to die surface.
2, the blade after demoulding carries out the construction pretreatment procedure such as polish.
3, in blade surface coating process, the blade with protective layer is ultimately formed.
Since paint coatings are constructed outside mould, coating only needs to guarantee on the blade resin of paint film after hardening
There is adhesive force, without considering the blade resin of mold and liquid.But there are numerous shortcomings in actual application, than
Such as, blade blank needs to polish, and dust floats the secondary pollution for causing product, equipment, while bringing pole to Health Status For Workers Exposed
It is big unfavorable.Blade blank polishing rear surface pin hole is numerous, needs to be filled using additional putty.Furthermore paint curing is applied
Work coating needs to occupy the independent workshop except molding, and such technique brings very high equipment, personnel and time to blade construction
Cost.
In view of the existing numerous shortcomings of paint coatings construction, it has been proposed that forming wind using gel coat technique in mould
Electric blade protection layer.Gel coat technique refers in so-called mould constructs one of gel coat in advance in mould inside, reaches finger pressure to the gel coat
After dry (standard No. GB 1728), then the conventional of blade is carried out on the gel coat, production is perfused.
For gel coat in mould, coating object is mold, and gel coat itself is the coating object that resin is perfused in mould；Simultaneously
Then completely not so the design of gel coat must be taken into consideration the matching with mold in mould, and coating.
Furthermore gel coat must assure that without adhesive force on mold, while it is attached to guarantee that blade resin has on gel coat film again
Then completely not so put forth effort, and coating.
Therefore, in mould gel coat and coating concrete composition, design function, application mode and in terms of all completely
It is different.
The purpose of gel coat major design is the tiny flaw for eliminating or reducing blade surface in existing mould, to reduce subsequent painting
The workload of dress.Gel coat mainly includes gel coat and the slow poly- ammonia of curing elastic polyurea type in polyester polyether polyurethane mould in existing mould
Gel coat in ester mould, both gel coats generally existing following problems in actual application:
1. gel coat, which exists, in polyester polyether polyurethane mould accounts for mould time length (1-5 hours), difficult problem is demoulded.Blade mould
Tool cost is all million ranks, therefore such product can be substantially reduced the service efficiency of mold, increases invisible cost.In addition, being
It convenient for demoulding, needs additionally to increase cooling system outside mold, can directly increase cost.
2. gel coat is there is also mould time long (1-5 hours) are accounted in resilient polyurea type polyurethane mould, in addition, due to this
Gel coat needs additionally to increase cooling system outside mold, can directly increase cost.
3. the weatherability of two kinds of gel coats is not high, light-protection rate is low.The coating that need to additionally construct just is able to satisfy finally wanting for blade
It asks.
Therefore, in view of the above-mentioned problems, gel coat scheme can not directly replace blade paint coatings side completely in existing mould
Case.
Summary of the invention
For the problem that curing time present in gel coat in existing mould is long, weatherability is not high, the main object of the present invention
It is to provide gel coat in a kind of high-weatherability and the wind electricity blade polyureas mould of expediting setting type.
In order to achieve the above object, the present invention adopts the following technical scheme that:
Gel coat in a kind of wind electricity blade mould, gel coat includes host agent and curing agent in the mould；
The host agent comprises the following components in parts by weight:
The Resin A is two secondary amine compound of non-polyether amine；
The resin B is two secondary amine compound of polyether amine；
The hardener dose is the 50-100% of weight resin in host agent.
Preferably, two secondary amine compound of non-polyether amine is by maleic acid ester type compound or fumaric acid esters chemical combination
The primary diamines class of object and non-polyether structure closes object by two secondary amine class rigidizations made of Michael addition reaction.
Preferably, two secondary amine compound of polyether amine is by maleic acid ester type compound or fumaric acid esters compound
Pass through two secondary amine class flexible compounds made of Michael addition reaction with the primary diamines class of polyether structure.
Preferably, the maleic acid ester type compound be diethyl maleate, dimethyl maleate, dipropyl maleate or
The mixture of one or more of dibutyl maleate.
Preferably, the fumaric acid esters compound be diethyl fumarate, dimethyl fumarate, fumaric acid dipropyl or
The mixture of one or more of dibutyl fumarate.
Preferably, the primary diamines class of the non-polyether structure be hexamethylene diamine, 4.4 ' diamino-dicyclohexyl methanes,
One of 3.3 ' diamino-dicyclohexyl methanes of dimethyl -4.4 '.
Preferably, the primary diamines class of the polyether structure is the polyetheramine that molecular weight is 200,230,400 or 600.
Preferably, the filler is weather-proof rutile type titanium white.
Preferably, the curing agent be Desmodur N100, Desmodur N3300, Desmodur N3600,
One of Tolonate HDT, aliphatic performed polymer that isocyanates (NCO) weight content is 1~20%.
Gel coat is tested through experiment in the mould constituted based on above scheme, relative to gel coat in existing mould, curing time
It greatly shortens；Weather resistance is greatly improved simultaneously, realizes the high-weatherability and expediting setting type of gel coat in mould, can directly replace leaf
Piece paint coatings.
Furthermore Ben Monei gel coat is in use, have the further advantage that
1, it compares in both the above mould for gel coat, has and be swift in response, account for the mould time (< 1 hour) short advantage, it can
Mould utilization factor is effectively increased, blade entirety production efficiency is accelerated.
2, it compares in weatherability polyester polyether polyurethane mould for gel coat, there is obvious weather-proof advantage, and be easy to
Demoulding does not need additionally to increase cooling equipment.
3, coating, other positions (account for about blade area 90%) only need to be done in die-closed position using the leaf of Ben Monei gel coat
Coating is not needed.Whole coating process are then needed using the blade of gel coat in old mould.
4, it compares in weatherability resilient polyurea type polyurethane mould for gel coat, there is more apparent weather-proof advantage, Yi Jiji
Low irritation (because being swift in response, small molecule amine can not volatilize), it is friendly to construction personnel's health.
Specific embodiment
In order to be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, tie below
Specific example is closed, the present invention is further explained.
For generally existing the accounting for of gel coat in existing mould, the mould time is long, and weatherability is not high, the low problem of light-protection rate, we
Case provides gel coat in a kind of mould based on two secondary amine compound of non-polyether amine, and gel coat has weather-proof in the mould constituted accordingly
Property height and the fast advantage of curing rate are, it can be achieved that direct substitution blade paint coatings truly.
Based on the above principles, glue in the high-weatherability and the wind electricity blade polyureas mould of expediting setting type that this programme provides
Clothing, including host agent and curing agent.
The host agent comprises the following components in parts by weight:
