Abstract
The waterproof pitch is produced with pitch as base material and through heating, adding SBS in high speed shearing and stirring, adding base oil as softening agent, adding bentonite and super water-absorbing resin and full stirring. It has excellent shape maintaining capacity, relatively high heat resistance and elastic restore capacity, moderate water absorbing capacity, excellent durability and self water sealing performance. It may be used in liquid state to reach where solid material can not not reach via self leveling.
Description
Technical field:
The present invention relates to a kind of water-swelling functional materials, can be widely used in the waterproof of underground works, underwater engineering, covil construction etc.
Background technology:
Water uptake expansion material is novel compound functional materials.At present, what water-swellable material was the most frequently used is: sulfide type (also claiming the goods type) water swelling rubber, non-vulcanization type (also claiming the putty type) water swelling rubber, the former, complex process, processing difficulties needs sulfuration, be difficult for pointing, on-the-spot continued access difficulty, both sides, opposite joint chamber need be done levelling and handle.Latter's intensity is low, and rebound resilience is little, and the long period of soaking precipitate is more, and construction will be made sealing treatment.And water swelling rubber is to be that matrix develops with rubber, and cost is higher.Therefore define applying of these products.
Technology contents:
The objective of the invention is to be raw material with pitch, through modification, develops a kind of water-swelling type water proofing asphalt.
Purpose of the present invention realizes in the following manner: be matrix with pitch, the heating back adds styrene-butadiene-styrene block copolymer (being called for short SBS) and high speed shear stirs, adding the base oil tenderizer again stirs, add wilkinite and polyacrylic super-strong moisture absorbing resin simultaneously, fully stir and form.Prepared water-swelling type water proofing asphalt component and ratio are: plain asphalt 95%～25%, styrene-butadiene-styrene block copolymer (being called for short SBS) 1～15%, base oil 2～10%, polyacrylic super-strong moisture absorbing resin 1～20%, wilkinite 1～30%.
Pitch carries out the water-swelling type water proofing asphalt that above-mentioned modification makes, and has the elastic restoring force that thermoplasticity is become reconciled, and can construct under liquid state, from levelling, can be used for the solid material place that is beyond one's reach, and cost is low.
Embodiment:
Describe composition of the present invention and preparation method in detail below in conjunction with embodiment.
Preparation modifying asphalt: take by weighing a certain amount of pitch in mixing vessel, in oil bath, be heated to about 180 ℃, add the styrene-butadiene-styrene block copolymer (being called for short SBS) that accounts for pitch amount 15% then, rotating speed with about 3500 rev/mins under the constant temperature carried out shear agitation 1 hour, add the base oil tenderizer that accounts for pitch amount 10% again, continue stirring and just made modifying asphalt in 1 hour.The softening temperature of the modifying asphalt of gained is at 125 ℃～135 ℃, and low temperature flexibility is at-20 ℃～-25 ℃, and after the layering test, the relative error of epimere and hypomere softening temperature is less than 5%.
Carry out the preparation of water-swelling type water proofing asphalt then: take by weighing a certain amount of modifying asphalt, in oil bath, be heated to 170 ℃, add polyacrylic super-strong moisture absorbing resin that accounts for modifying asphalt amount 8% and the wilkinite that accounts for modifying asphalt amount 20%, under the constant temperature, stir half an hour with 1200 rev/mins rotating speeds.Prepared water-swelling type water proofing asphalt has good shape hold facility, higher temperature capacity and elastic recovery capability are arranged, and its water-retaining capacity is moderate, superior in durability, at pressure (gauge pressure) is below the 0.1Mpa, has the selfsealings performance with the water sealing.Can construct under liquid state, from levelling, can be used for the solid material place that is beyond one's reach, it combines the advantage of goods type and putty type water swelling rubber, and cheap, and popularizing application prospect is good.If this kind material is used for the waterproof concrete, more strengthened the reliability of water proofing asphalt concrete, to guaranteeing the buildings antiseepage, guarantee that the safety of dam, water channel and underground works is significant.
Claims (1)
1. water-swelling type water proofing asphalt, with pitch is matrix, the heating back adds styrene-butadiene-styrene block copolymer (being called for short SBS) and high speed shear stirs, adding the base oil tenderizer again stirs, add wilkinite and polyacrylic super-strong moisture absorbing resin simultaneously, fully stir and form, it is characterized in that water-swelling type water proofing asphalt component and ratio are: plain asphalt 95%～25%, styrene-butadiene-styrene block copolymer (being called for short SBS) 1～15%, base oil 2～10%, polyacrylic super-strong moisture absorbing resin 1～20% is in the swelling 1～30%.
