Abstract
The invention provides a preparation method of a degradable cement structure joint filling and separation composite material. The method comprises the following steps: obtaining a plant powder main body composite sheet material by taking plant micro-powder, soluble starch, cellulose micro-powder and high-water-absorbing quality resin powder as raw materials; and pouring by taking polymethylene polyphenyl isocyanate, a foam stabilizer, polyether polyol and dichlorofluoroethane as raw materials and compounding to obtain the cement structure joint filling and separation composite material which contains a polyurethane elastic foam sealing strip and has a degradable main body. A main body sheet material part of the composite material can be cracked and degraded after a cement structure is cured and finally the composite material basically disappears; the releasing of stress is eliminated when the cement structure is hotly expanded and coldly contracted, and rainwater, snow water and crushed gravels are effectively prevented from entering a flexible joint so that the service life of the cement structure is prolonged; and the composite material has very positive and remarkable use effects in a structure building process of a cement road, and dust and noise pollution caused by the fact that the flexible joint of the cement structure is cut by an existing method is eliminated.
Description
Technical field
The present invention relates to the preparation method of a kind of degradable cement structures joint filling isolation composite, belong to Concrete Highway building materials field, be specifically related to a kind of adopt the blended mold pressings such as soluble starch, plant micropowder, cellulosic micropowder, super absorbent resin micro mist again with elastic polyurethane foam material cast compound obtain a kind of containing elastic polyurethane foam seal bar and the joint filling of main body degradable cement structures isolation composite preparation method.
Technical background
The cement such as cement pavement, cement court structures are very common in our daily life, in the casting process of cement structures, to amount of heat be discharged due to during cement setting sclerous reaction, cause concrete temperature to raise, after reaction terminates, cement structures temperature starts to decline, in temperature-fall period, due to concrete setting and harden, the contraction that cooling produces will cause structures to ftracture, and fractuer direction is relatively more random, has a strong impact on structures quality and service life.Therefore, generally after cement structures setting and harden, spacing 4 ~ 6 meters will cut expansion joint, and stress when cement structures can be induced like this to meet the pre-thermal expansion of cold events produces along cutting crack, prevents stochastic crack and arches upward.During cutting expansion joint, also will select suitable clipping time, if saw kerf too late, concrete may be in tension state, and when sawing from one end, monoblock road plate will be run through in discontinuous crack, will produce hidden trouble to concrete road surface.Having cut top, rear expansion joint in addition also wants asphalt reperfusion or fluid sealant to seal, and prevents rainwater, snow-broth enters and enter to the destruction of roadbed and blinding the effective result of use reducing expansion joint.And when gap flexible to the cement structures cutting after solidification, larger noise and pollution can be produced, and consume more electric energy and manpower and materials.Cut again after cement solidification to prevent at present, plank, bamboo clappers, rubber strip or polystyrene foam plate etc. can be used to carry out isolation at a certain distance fill when building with cement mixing material, the use of these planks, rubber strip or polystyrene foam plate, effectively can prevent the shrinkage cracking phenomenon in cement structures temperature-fall period.But in these materials, plank, bamboo clappers are harder, when pre-thermal expansion in cement structures summers, dilation dimension can be affected, swelling stress is discharged not thorough, cement structures will be caused like this to arch upward or produce check crack, if take out plank, bamboo clappers after the construction of cement structures, then time-consumingly to take a lot of work.The soft goods such as rubber strip or polystyrene foam plate is favourable to release stress, but when cement structures are poured into a mould, because its intensity is lower, is easy to deformation, causes expansion joint yielding, not straight, affects attractive in appearance and construction effect.Take a lot of work when the pitch or fluid sealant that prevent rainwater, snow-broth and blinding from entering are poured in top, expansion joint loaded down with trivial details.The invention provides a kind of employing soluble starch, plant micropowder, cellulosic micropowder, the blended mold pressings such as super absorbent resin micro mist obtain containing elastic polyurethane foam seal bar with the cast of elastic polyurethane foam material and main body degradable joint filling isolation composite again, isolated material use is filled in the joint filling that this composite can be used as cement structures, production technology is simple, convenient to use, one-shot forming, time and labour saving, energy-conserving and environment-protective, after the solidification of cement structures, the main part of joint filling isolation composite can start degraded of bursting apart, the filler in separation layer is finally made substantially to disappear complete, the release of counter stress when cement structures expand with heat and contract with cold can be eliminated completely, and elastic polyurethane foam seal bar effectively can prevent rainwater, snow-broth and blinding enter expansion joint, there is effect in that guarantees expansion joint, extend the service life of cement structures.These invention goods are in the work progress of cement structures, there is positive and significant result of use, eliminate the dust of generation when existing method is cut cement structures, noise pollution, also eliminate the consumption to saw blade and electric energy, decrease the waste to manpower and materials, this invention is a kind of novel cement structures joint filling isolation composite product, is particularly suitable for the instructions for use of cement floor expansion joint.
(the plastics industry such as Ying Zongrong, Vol.36 No.1 2008) with Plant Powder and Poplar Powder for Plant Powder/wood flour composite material prepared by raw material, have studied wood powder process, wood powder consumption to the impact of composite property, and composite morphosis is observed.Result shows, compared with untreated wood powder, wood powder surface coupling processing makes Compound Material Engineering intensity slightly decline, and alkali treatment is not obvious to the raising of Compound Material Engineering intensity.Increase with wood powder consumption, the hot strength of composite and bending strength reach the highest when wood powder mass fraction is 40% and 20% respectively, exceed 41.8% and 31.6% respectively than the intensity of pure Plant Powder, and composite is pseudoplastic fluid, increase with wood powder consumption, shear viscosity increases.
