Description
Technical field
The invention belongs to test piece mould technical field, relate to a kind of test piece mould design, be specifically related to a kind of for silicone adhesive tensile test specimen mould.
Background technology
In recent years, China's silicone sealant industry has been stepped into development fast traffic lane, the development of sealing neutral silicone resin series of products is well afoot also, a lot of products are put on market, not only meet the ever-increasing demand of building industry, and promoted double glazing, glass curtain wall, out-hung panel and metal framework adhesive structure etc. to build the development of new product, new construction, new technology.The leading manufacturing enterprise of domestic silicone building sealant, on the basis of pilot scale production technology of introducing national organosilicon engineering center neutral silicone building sealant, has carried out the research and development of series of products, obtains impressive achievement.Although the existing many units of China and enterprise develop silicone adhesive product, part kind has also realized suitability for industrialized production, compares still have larger gap with Foreign Advanced Lerel.
Silicone sealant is called for short silicone adhesive and belongs to silicone based product, to take a kind of encapsulant that hydroxy-end capped polysiloxane makes as base-material, compare with the molecular organic fluid sealant of other high scores, its bonding force is stronger, large and the excellent performance of resistance to outdoor aging of pulling strengrth, moistureproof, anticorona, and there is good high-low temperature resistant, water resistance, be difficult for xanthochromia, oil-tight, can realize and most of building material product between bonding.Therefore, can be used as sealant, adhesive, embedding agent, be widely used in the new high-tech industry fields such as building, automobile, machinery, electronics, weaving.
Silicone adhesive can be divided into one-component and two large class of component two by the component of product, one-component silicone adhesive is a kind of similar ointment, once the moisture in ingress of air will be solidified into a kind of material of tough and tensile rubber-like solid, two component silicone adhesives refer to that silicone adhesive is divided into two groups of A, B, any one group of individualism all can not form curing, but two groups of rubber cements mix by a certain percentage and just can react curing.Common one-component silicone adhesive is divided into de-acetic acid type, dealcoholized type, ketoxime removing type and de amide type etc.At present, ketoxime removing type product accounts for the leading position in market.
Solidifying of one-component silicone adhesive, after being first the moisture in crosslinking chemical contact atmosphere, there is rapidly hydrolysis reaction in the functional group of hydrolyzable, generates silanol.Si-OH base of its silanol and 107 glue
si-OH base is sent out condensation reaction, makes silicone adhesive curing cross-linked, forms tridimensional network, becomes elastic body.
Test about Bond Strength is to check the test that whether can form bonds well between silicone adhesive used and base material, and because base material is of a great variety, its surface treatment form and processing horizontal also vary, and does not also have at present a kind of glue can guarantee all base materials all necessarily to bond.Therefore,, for some concrete engineerings, the fluid sealant that must select it and base material carry out Test about Bond Strength to guarantee that bonding well.The gross data of putting into practice engineering as silicone adhesive supports, and it is particularly important that Test about Bond Strength seems, in the process of making test specimen, must guarantee the deeply-curing that the regular and test specimen of sample dimensions can be good.
At the < < elastic sealants such as Huang Yingchang and adhesive > >, mention, when the surface drying of rubber cement is too fast, after the top layer of glue or shallow-layer district absorb water rapidly and solidify, the surface of glue has just formed a kind of tridimensional network, strand is arranged closely, hindered steam further to rubber cement internal divergence, thereby deeply-curing is slowed down.In the < < silane crosslinkers such as Chen Ping Yao and coupling agent modified silicone sealant research > >, also draw and work as rubber cement surface drying very in short-term, the conclusion that its curing depth reduces on the contrary.In order to raise the efficiency, the silicone adhesive surface drying time of major part is all shorter now, if require surface drying neutral silicone glue silicone adhesive energy large area contact moisture energy fast demoulding in making test specimen process faster, so just can solve the problem that hinders deeply-curing, there is part silicone adhesive surface drying time longer, if the moisture absorption, makes silicone adhesive fully curing with regard to energy fast demoulding preferably.So this patent has been studied a kind of mould of making silicone adhesive test specimen of good permeability, to provide experimental data accurately to carry out the enforcement of propping works.
Through retrieval related documents, there are no the play-by-play about silicone adhesive tensile test specimen Design of Dies.
Summary of the invention
The object of the present invention is to provide a kind of effective and good permeability, be conducive to silicone adhesive test specimen deeply-curing well, little to guarantee silicone adhesive data of mechanical standard deviation, result accuracy is high, and can make the silicone adhesive tensile test specimen mould of silicone adhesive test specimen fast demoulding.
In order to realize the above-mentioned effect of mentioning, the technical solution used in the present invention is:
A silicone adhesive tensile test specimen mould, setting comprises: spacer pad I, spacer pad II, clamping plate I, clamping plate II, securing member and/or holder; Described spacer pad I and spacer pad II are separately positioned on the two ends of test piece mould; Described clamping plate I and clamping plate II are separately positioned on the both sides of spacer pad I and spacer pad II; Described securing member arranges 1-2, and the outside or the two ends that are enclosed within spacer pad I, spacer pad II, clamping plate I and clamping plate II fixedly obtain this silicone adhesive tensile test specimen mould.
Above-described holder is H shape, and upper end is connected with spacer pad I is fixed or movable, and lower end is flexibly connected with spacer pad II.
The material that above-described spacer pad I, spacer pad II and holder adopt comprises: timber, pottery, plastics, metal and stone material.
The material that above-described clamping plate I and clamping plate II adopt comprises: glass, plastics, pottery, metal and stone material.
