Abstract
The present invention discloses polymer asphalt waterproof paint, a preparation method thereof and the application thereof. The waterproof paint comprises 40 to 60 wt% of asphalt, 2 to 5 wt% of polyvinyl alcohol, 1 to 3 wt% of 1831, 7 to 25 wt% of neoprene latex, 0.5 to 5 wt% of antifoaming agent, 0.1 to 5 wt% of oxalic acid dihydrate, 1 to 5 wt% of cobalt nitrate, 5 to 20 wt% of talcum powder, 7 to 15 wt% of natural rubber and 2 to 5 wt% of acyloxy methylcellulose in 1000 kilograms of water. The waterproof paint can be used as a special waterproof material of bridge floors, a waterproof material of roofs and pipe culverts, and an anticorrosive material of pipelines and containers.
Description
Technical field
The present invention relates to a kind of waterproof paint, relate in particular to a kind of waterproof paint of polymer and asphalt.
Technical background
Existing waterproof paint of polymer and asphalt, its low temperature flexibility and thermotolerance are all undesirable, embrittlement can occur when temperature reaches below-15 ℃, and trickling, foaming phenomenon can occur when surpassing 80 ℃.In addition, existing this class waterproof paint is not also had alkali resistance and an acid resistance.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency of the prior art, and provide a kind of low temperature flexibility and thermotolerance high and the alkaline-resisting and acid proof waterproof paint of polymer and asphalt of tool.
Another object of the present invention is to provide a kind of method for preparing above-mentioned waterproof paint of polymer and asphalt.
A further object of the present invention provides the purposes of above-mentioned waterproof paint of polymer and asphalt.
Waterproof paint of polymer and asphalt of the present invention is a FYT series polymer asphalt bridge floor water-proof material.FYT is the abbreviation of FlyoverYoke Tarpaulin, and its implication is: the bonding water-proof material of highway overbridge.
The technical scheme that reaches above-mentioned purpose of the present invention is as follows:
Waterproof paint of polymer and asphalt of the present invention is for containing the following component by its weight percent meter in 1000 kilograms water:
Pitch 40-60% polyvinyl alcohol 2-5% 1831 1-3% polychloroprene latex 7-25% defoamer 0.5-5% oxalic acid 0.1-5% Xiao Suangu 1-5% talcum powder 5-20% natural gum 7-15% carboxymethyl cellulose 2-5%
The method for preparing the above-mentioned waterproof paint of polymer and asphalt of the present invention comprises the steps:
1. pitch is heated to 140 ℃;
2. polyvinyl alcohol, 1831, Xiao Suangu, talcum powder and carboxymethyl cellulose are mixed with 1000 kilograms water and obtain softening water;
3. it is even by the colloidal mill ground and mixed with above-mentioned softening water to 140 ℃ pitch to heat;
4. in the above-mentioned material that mixes, add neoprene latex, defoamer, oxalic acid and natural gum, and mix
Obtain the waterproof paint of polymer and asphalt of finished product.
Waterproof paint of polymer and asphalt of the present invention can be used as bridge floor special-purpose water-proof material, roof waterpoof material, culvert water-proof material and pipeline, the container impregnating material is used.
The advantage of waterproof paint of polymer and asphalt of the present invention is:
1, broad thermal adaptability is arranged, under 140 ℃ high temperature, do not trickle and bubble, not embrittlement under-20 ℃ low temperature.
2, paint solidification film forming piece, its film forming good toughness at short notice can film forming, can shorten the waterproof construction time;
3, cohesive force is strong, and the integral waterproofing performance is good;
4, its acid resistance is for using 2%H
2SO
4Liquid soaked 15 days, the no change of filming;
5, its alkali resistance is for soaking 15 days the no change of filming with 2%NaOH liquid;
6, nontoxic, nonflammable.
Below in conjunction with embodiment, waterproof paint of polymer and asphalt of the present invention is further described.
Embodiment
In one embodiment of the invention, waterproof paint of polymer and asphalt of the present invention contains the following component by its weight percent meter in 1000 kg water:
Pitch 50% polyvinyl alcohol 3% 1,831 2% polychloroprene latex 15% defoamer 4% oxalic acid 2% Xiao Suangu 3% talcum powder 8% natural gum 10% carboxymethyl cellulose 3%
Talcum powder wherein adopts granularity to be about 200 purpose lightweight talcum powder.
When waterproof paint of polymer and asphalt of the present invention is used as FYT series waterproof bridge floor material, before this waterproof paint of brushing (or spraying), concrete laitance, smooth uneven place be should at first cut, greasy dirt, rubbish etc. removed, and thoroughly remove the foreign material such as wooden model, reinforcing bar, iron wire at crashproof wall and concrete bridge deck handing-over position, thoroughly clean basal plane then; This waterproof paint of brushing on basal plane (or spraying), when being coated with the first layer, to dilute by suitable therein fusion certain amount of surfactant solution, to impel it to mix the basal plane capillary-size pore, thereby improve the cohesive strength and the slip resistance of waterproof paint layer, brushing (or spraying) second and third, four ... all over the time, go up and could brush after a coating is done solid work (or spraying) again.
