Description

A kind of glued membrane manufacture method extending storage period
Technical field
The invention belongs to polymer matrix composites field, relate to a kind of glued membrane manufacture method extending storage period.
Background technology
Glued membrane is a kind of resin adhesive of film like, be mainly used in by bonding for two kinds of products be a complete product, carrier free glued membrane and carrier adhesive can be divided into, carrier adhesive adhesive resin is coated in one deck carrier (as fabric or nylon wire etc.) above glued membrane formed, and carrier free glued membrane is the glued membrane be prepared from by pure adhesive resin.
The most frequently used glued membrane of field of compound material is epoxy resin glued membrane, and this glued membrane is generally made up of matrix resin, properties-correcting agent and solidifying agent etc.Because each component of glued membrane mixes uniformly, under room temperature environment, epoxy resin can react at leisure, its storage period is at room temperature shorter, therefore under generally all epoxy resin glued membrane being stored in the low temperature environment of-18 DEG C, to extend the storage period of glued membrane, and in order to ensure its mechanical property, in use strict gate ring epoxy resins glued membrane open-assembly time at room temperature, the room temperature open-assembly time of general epoxy resin glued membrane is no more than 200h.
Summary of the invention
The present invention is directed to the problem restricting existing glued membrane extended pot life, propose new glued membrane manufacture method, extend the storage period of glued membrane, and reduce the requirement to storage environment.
Original glued membrane manufacture method be by each component of tackiness agent by dissolving, each component mixes by melting or the means such as blended, is then membranaceous glued membrane by tackiness agent brushing or film.And glued membrane of the present invention with matrix resin and solidifying agent for major ingredient, prepare resin membrane and solidifying agent film respectively, in addition, this glued membrane is also auxiliary material with auxiliary agent.
The glued membrane manufacture method that the present invention proposes is that each component of composition tackiness agent is divided into two-layer or multi-layer resinous film and manufactures respectively, each layer resin film layer is stored respectively, namely in manufacture and storage process, the matrix resin reacted in tackiness agent and solidifying agent is carried out physical isolation.Because matrix resin and solidifying agent do not have contacting of physics, resin membrane self can not react, and curing agent resin film self can not react, and therefore resin molding can obtain relatively long working life without the need to low tempertaure storage.
Technical scheme of the present invention takes following steps:
Step 1: first carry out redistributing of glued membrane component, each component of glued membrane is divided at least two membranes, first tunic is mainly matrix resin, second tunic is mainly solidifying agent, in glued membrane formula, other auxiliary agent both can be mixed in resin membrane, also can be mixed in curing agent resin film, also can make separately becomes one deck resin molding, finally determines the mass area ratio of each layer resin molding according to formula.
Step 2: prepared by resin molding.According to the mass area ratio of each layer resin molding that step 1 is determined, corresponding component is manufactured resin molding respectively, during the preparation of resin molding, both resin can have been brushed film forming also can by blade coating film forming after resin melting or compacting film forming, make each layer resin molding after film forming adopt respectively barrier film or separate-type paper coated, and deposit separately, owing to achieving the physical isolation of matrix resin and solidifying agent, each layer resin molding can not react, at room temperature store, without the need to low tempertaure storage, the storage period of resin molding is unrestricted simultaneously.
Step 3: the compound of glued membrane.Only before glued membrane uses, the principle mixed according to glued membrane determines the relative ranks of each layer resin molding, be a flood glued membrane by each layer resin molding successively paving, then as required by the glued membrane paving of flood to treating bonding article surface, each layer resin molding melting in resin molding solidification process also realizes mixing, finally completes the curing reaction of glued membrane.
The glue film manufacturing process extending storage period of the present invention is that the matrix resin in glued membrane and solidifying agent are separately made, deposited, to realize the object of glued membrane extended pot life.
Mark is by 60 parts ~ 99 parts epoxy resin by weight for glued membrane of the present invention, and 1 part ~ 40 parts solidifying agent and 0 part ~ 10 parts other auxiliary agent preparations form.
Matrix resin of the present invention is a kind of or wherein several combination in bisphenol A type epoxy resin, bisphenol f type epoxy resin, alicyclic type epoxy resin and phenol aldehyde type epoxy resin.
Solidifying agent of the present invention is a kind of or wherein several combination in amine curing agent, imidazole curing agent, acid anhydride type curing agent.
The glued membrane extending storage period of the present invention is at least made up of one deck resin membrane and one deck curing agent resin film.
In glued membrane of the present invention, various auxiliary agent can be mixed and made into resin molding with matrix resin, makes resin molding after also can mixing with solidifying agent, also can be made into resin molding separately.
The glued membrane of prolongation of the present invention storage period replaces laying by resin membrane and curing agent resin film and possible various auxiliary agent resin moldings to form.
Resin membrane of the present invention and curing agent resin film make respectively, store, and both are physically-isolated before use.
Of the present invention composition extend storage period glued membrane each layer resin molding only glued membrane use or solidification before just in order laying form together.
Adhesive matrix resin molding of the present invention and curing agent resin film can adopt spread coating to make, also employing spread coating or pressed film method can be made the resin molding that one deck is uniform, have certain mass area ratio.
Resin membrane of the present invention and curing agent resin film can be only resiniferous resin moldings, also can be the resin moldings including carrier.
The glued membrane manufacture method that the present invention proposes is that each component of composition tackiness agent is divided into two-layer or multi-layer resinous film and manufactures respectively, each layer resin film layer is stored respectively, namely in manufacture and storage process, the matrix resin reacted in tackiness agent and solidifying agent is carried out physical isolation.Because matrix resin and solidifying agent do not have contacting of physics, resin molding self can not react, and curing agent resin film self can not react, and therefore resin molding can obtain relatively long working life without the need to low tempertaure storage, reduces storage cost.Only just resin membrane and curing agent resin film are combined with each other before glued membrane uses, extend the duration of service of material, reduce use cost.
