Abstract
The invention provides a kind of single-component cranny filler of polyurethane foam, including Pluronic polyols, realizes polyurethane foam disposable foaming after ejection, avoids the moisture sprayed in foam re-absorption air and carries out the waste that second time of foaming expansion is brought；Shaping speed is fast, and spray volume is easy to control, easy for construction, saves cost of labor.
Description
Technical field
The present invention relates to single-component cranny filler of polyurethane foam, belongs to polymer arts.
Background technology
Single-component cranny filler of polyurethane foam is with list by components such as base polyurethane prepolymer for use as, catalyst, foaming agent, propellants
A kind of special polyurethane products of branch inhalator jar form package storage.It has the advantages that preceding foaming, highly expanded, contraction are small, and
The intensity of foam is good, the foam after bonding force high solidification has the multi-effect such as joint filling, bonding, sealing, heat-insulated, sound-absorbing, is
A kind of environmental protection and energy saving, construction material easy to use, be applicable to sealing and plugging, fill a vacancy squeegee, it is fixed bond, heat preservation and soundproof,
The sealing and plugging and waterproof being particularly suitable for use between plastic-steel or aluminum alloy doors and windows and wall.Existing foamed glue product when in use may be used
The polyurethane materials of foam-like are instantaneously sprayed, foam material can expand under pressure, that is, realize one step foaming, then
The moisture reabsorbed in air is reacted, and releases carbon dioxide, then carries out second time of foaming, and foam reaches filling by solidification
Seal the purpose of building joint or hole.Single-component cranny filler of polyurethane foam used at present needs second time of foaming, constructs
Cheng Zhongxu sprays material more, causes to waste, can also produce unnecessary expander, it is necessary to artificial cutting is neat, cause Material Cost and
The increasing of cost of labor.
The content of the invention
The problem of for current single-component cranny filler of polyurethane foam one step foaming expansion effect difference, the present invention provide a kind of
Expansion rate is high, gelation rate is fast, is capable of the single-component cranny filler of polyurethane foam of rapid shaping.
To achieve the above object, the present invention adopts the following technical scheme that.
A kind of single-component cranny filler of polyurethane foam, include the raw material of following mass fraction：

PPG B, viscosity（25℃）For 220-300mPa.s, hydroxyl value is 160-170mg KOH/g.
The mass ratio of the PPG and modified polyether polylol is 10-15:5-10.
The catalyst is N,N-Dibenzylamine and trimethylolpropane using mass ratio as 1-2:10 mixing.
The modified polyether polylol is polyvinyls grafted polyether polyol.
The fire retardant is melamine phosphate, methyl-phosphoric acid dimethyl ester and three（2- chloropropyls）One kind in phosphate
Or several combinations and the mixing of chlorinated paraffin.
The foam stabilizer is Si -- C type silicone oil.
One or more of combinations of the propellant in propane, normal butane, iso-butane and the third butane.
The single-component cranny filler of polyurethane foam is prepared using following methods：
PPG, modified polyether polylol, fire retardant, catalyst, foam stabilizer is well mixed and then more with polymethylene
Phenyl Isocyanate is sequentially loaded into inhalator jar, then filling dimethyl ether and propellant on bottle placer again, shakes 3-5min,
24h is placed at room temperature, produces single-component cranny filler of polyurethane foam finished product.
The present invention has advantages below：
The invention provides a kind of combined polyether available for single-component cranny filler of polyurethane foam and its single group being prepared
Part cranny filler of polyurethane foam, employs Pluronic polyols, realizes polyurethane foam disposable foaming after ejection, keep away
The moisture for having exempted to spray in foam re-absorption air carries out the waste that second time of foaming expansion is brought；Shaping speed is fast, and spray volume is easy
Control, it is easy for construction, save cost of labor.
