Description
Technical field
The invention belongs to a kind of technical field of polymer materials.
Technical background
The PVC gloves have chemical resistance, flame retardant resistance, and intensity is high and be easy to the advantages such as processing, and the parent who generally is subject to people looks at.Owing to having added aborning a large amount of softening agent, difficult without surface-treated PVC gloves demolding, and dress poor performance.Traditional treatment process is to apply the smooth materials such as talcum powder or W-Gum in glove surface, to increase the surperficial smooth feeling of gloves.Yet powdered lubricant can cause the pollution of production process and use procedure, and serious meeting causes some crowd irritated after wearing has powder PVC gloves.For the cross infection of stopping medical personnel and patient and the experimental pollution problem of daily biochemical investigation, western developed country has forbidden having the production and sales of powder gloves.So substitute without powder the powder trend that has been inevitable arranged.
The PVC gloves are from having powder to without powder, and treatment process both domestic and external has the xanthan gel method, halogenation treatment method, polymer emulsion cladding process etc.Halogenation treatment causes environmental pollution owing to producing chlorine in preparation process, and makes production complicated.The gloves paracentesis resistance that the polymer emulsion cladding process is produced is poor, and the slipping aspect is not as good as the powder gloves are arranged.PVC gloves use polyurethane finishing agent is simple with production technique, good emulsion stability, and the elasticity of film forming, drawing force and cutting resistance well are subjected to people's favor deeply.But constantly surging along with price and wage for workmen, the corresponding raising of production cost causes PVC gloves domestic markets prospect to allow of no optimist, and is the problem of present PVC manufacturing enterprise overriding concern so reduce production costs.The penetrating degree of the outward appearance of present domestic WPU is inadequate, and smooth degree is inadequate, and extensibility is also bad, the resin light intensity.Chinese patent CN200810113037X discloses a kind of preparation method of PVC gloves high dilution ratio aqueous coating agent, do not add flatting silica class material but the limited extinction effect that reaches of employing consistency in its preparation process, yet consider the hot sticky cold crisp of acrylic resin, the heat resistanceheat resistant adhesive of this resin is also bad, finds this resin molding adhesion more than 35 ℃ through our repetition test.
Summary of the invention
The purpose of this invention is to provide a kind of aqueous hybrid resin and preparation method, inadequate to solve the penetrating degree of prior art outward appearance, smooth degree is inadequate, and extensibility is also bad, the resin light intensity, and the heat resistanceheat resistant adhesive is poor, the problems such as production cost height.
The technical solution adopted for the present invention to solve the technical problems is to adopt Ts-100 to replace traditional silicon-dioxide flatting silica, can solve the not penetrating and too strong problem of resin light of film outward appearance.
Add the waterborne organic silicon surface slip agent, but add-on do not affect under the prerequisite of clinging power of resin, solve the inadequate problem of the smooth degree of resin.Replace the part urethane resin with acrylic resin, so namely reached the extensibility that the purpose that reduces production costs has strengthened again resin.Raw materials component and the weight part proportioning of hybrid resin are: soft resin 50-70kg in urethane, soft resin 25-40kg in vinylformic acid, Ts-100 0.2-0.5kg, waterborne organic silicon surface slip agent 1-1.2kg, 245 0.1-0.3kg, 440 0.1-0.3kg, Diethylene Glycol butyl ether 0.2-0.6kg, cellulose thickener 2-3.5kg.
Described 245 is Siloxane-Oxyalkylene Copolymers aqueous wetting agents;
Described 440 is Siloxane-Oxyalkylene Copolymers water-based flow agents;
Its preparation method processing step is as follows:
Composite: by said ratio, with soft resin in urethane, soft resin in vinylformic acid, TS-100, the waterborne organic silicon surface slip agent, 245,440, the Diethylene Glycol butyl ether joins respectively in reactor, stirs 20-30 minute, obtains mixed liquor, and is standby;
Thickening: at the uniform velocity drip cellulose thickener after above-mentioned feed liquid mixes, after arriving the viscosity of 350-550 centipoise, stop dripping, stir after 20-30 minute, obtain the aqueous hybrid resin.
Useful technology of the present invention is embodied in the following aspects:
1, the aqueous hybrid resin of the present invention's preparation has the incomparable extensibility of conventional PU.As follows
TableShown in:
The principal feature of this resin is that the film outward appearance is penetrating, and is smooth, and unit elongation can reach more than 300%.Having added acrylic resin to reach in producing compound process reduces production costs and strengthens ductile purpose.
2, add flatting silica to solve the blocking under warming problem of resin.The suspension of TS-100 flatting silica is fairly good, does not also affect the permeability of film.20 times of placements of this aqueous hybrid resin dilution are reached 10 days flatting silicas also there is no sedimentation.
3, the water-borne acrylic resin in hybrid resin can fine and close film forming, can provide better anti-pin hole effect thereby can form than the thicker more compact film of conventional P U.
4, this resin has dual extinction effect by the limited extinction effect that reached of consistency, has added the TS-100 flatting silica to make this resin extinction better.
5, the hybrid resin of the present invention's preparation has reduced production cost, but does not reduce result of use.
