The specific embodiment
In conjunction with following examples the present invention is further described.
Embodiment 1
One of a kind of specific embodiment with cartridge that reaction equation removes the steam function of the present invention like Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, includes cylindrical shell 1; Cylindrical shell 1 has ccontaining cavity 2; One end of cylindrical shell 1 is provided with glue discharging mouth 3, and the other end of cylindrical shell 1 is provided with rear seal-cover 6, and being provided with in the ccontaining cavity 2 can be along the back blanking cover 4 of the interior move of ccontaining cavity 2; Wherein, Back blanking cover 4 is provided with cell body 10, be provided with in the cell body 10 can with water rapid-action low volatility liquid 9, low volatility liquid 9 vapour pressure at normal temperatures and pressures is less than 20Pa.Dewater with solid matter of the prior art and to compare; Of the present invention have a cartridge that reaction equation removes the steam function, when having steam to produce in the cylindrical shell 1, be positioned at the low volatility liquid 9 of the cell body 10 of back blanking cover 4 can be rapid and steam react; Thereby reach the purpose of removing steam; And because the volatility of low volatility liquid 9 is lower, the time that can in cell body 10, keep liquid is longer, has further prolonged the shelf-life that is stored in the sealant in the cylindrical shell 1; Simultaneously, the present invention installs the simple to operate of low volatility liquid 9, makes that its practicality is strong, is convenient to large-area popularizing and popularization on the market.
When filling sealant, back blanking cover 4 is positioned at the position near rear seal-cover 6, in the gap between rear seal-cover 6 and back blanking cover 4 low volatility liquid 9 is set; When using sealant, (for example: piston rod pressure), promote back blanking cover 4 and move, make that the sealant in the ccontaining cavity 2 is extruded from glue discharging mouth 3 to the position of glue discharging mouth 3 by external force.
In the present embodiment, the viscosity of low volatility liquid 9 is 10mPas~1000 mPas, and the weight of low volatility liquid 9 is 0.1g~10g.The time that can specifically store according to sealant is selected the weight of low volatility liquid 9, and for example: when sealant was preserved 15 days to 1 month, the weight of low volatility liquid 9 was selected 0.1g~1g; When sealant was preserved about 6 months, the weight of low volatility liquid 9 was selected 1g~5g; Preserve 12 months to about 18 months the time when sealant, the weight of low volatility liquid 9 is selected 5g~10g; Preferably, selection viscosity is the low volatility liquid 9 of 50mPas~1000 mPas, and it is rare excessively both to be unlikely to liquid, is coated in the cell body 10 and flows out, and is unlikely to feeding-up again, increases use cost.And, consider from the angle of financial cost, when the weight of selecting low volatility liquid 9 is 1g~5g, satisfy remove the requirement of steam in, have economy again, be comparatively commonly used at present.
In the present embodiment, low volatility liquid 9 is vinyltrimethoxy silane, VTES, to one or several the combination in Methyl benzenesulfonyl isocyanate, mute azoles alkane deicer, the triethyl orthoformate.In addition, this low volatility liquid 9 can also be used can satisfying and the water rapid reaction of other, and has the liquid replacement of low volatility requirement.
In the present embodiment, low volatility liquid 9 can directly be coated in the cell body 10.Specifically, one of method that can adopt spraying, dip-coating, perhaps brushing applies, the mode of preferred spraying, and the feasible interpolation difficulty that has not only reduced low volatility liquid 9, and simple to operate, interpolation efficient height, simultaneously pollution-free.
