Description
[technical field]
The invention belongs to building water-proof paint technical fields, and in particular to a kind of low temperature resistant asphalt waterproofing paint and its preparation
Method.
[background technique]
Water-repellent paint refers to the film that coating is formed, and a kind of coating that can prevent rainwater or underground water from leaking.It is anti-
Water paint is divided by coating state and form: emulsion-type, solvent type, response type and modified pitch.Emulsion-type, solvent type waterproof
Coating general cost is relatively high, is not suitable for large area and uses, so largely building uses asphalt waterproofing to apply in China at present
Material.But the weatherability of current most of asphalt waterproofing paint is poor, is easy aging, is especially easy hardening tortoise in low temperature environment
Leak is split, the waterproof effect of building is affected.Therefore, developing low temperature resistant, the non-aging asphalt waterproofing paint of one kind has very greatly
Development prospect.
[summary of the invention]
Goal of the invention of the invention is to provide a kind of low temperature resistant asphalt waterproofing paint and preparation method thereof, and the present invention passes through
Addition modified additive, modified plant ash solve the above problems in pitch, and modified additive and modified plant ash can be effectively improved
The cryogenic property of pitch, modified pitch ageing resistance is good, still has good needle penetration at low ambient temperatures, has good
Good crack resistance at low-temperature.
In order to achieve the above objectives, the technical scheme adopted by the invention is that: a kind of low temperature resistant asphalt waterproofing paint, by weight
Number meter, including following components: 70~80 parts of pitches, 3~5 parts of modified additives, 10~16 parts of modified plant ash, 6~8 parts of branches
Starch, 3~6 parts of sulphur powders, 6~8 parts of natural rubber powder, 1~3 part of anti-aging agent, 2~4 part of 2,6 1 di-tert-butyl cresol, 3~5
Part carbon black and 1~3 part of talcum powder.
In the present invention, as further explanation, the modification plant ash is prepared by the following method: in parts by weight
Meter, by 100~200 parts of rice straws after the kiln roasting plant ash that burn, grind into powder and mistake 200 meshes obtain vegetation ashes
Then plant ash powder and 50~80 parts of water phases are mixed and obtain suspension by end, stir in the mixing speed of 1000~1500r/min
Then 30~60min of lower immersion adjusts the pH value of suspension to neutrality with the sulfuric acid solution that mass fraction is 12~15%, uses
The strainer of 250 mesh filters out filter residue, then dries residue washing completely and in 60 DEG C of drying box with distilled water and obtain neutral grass
Neutral plant ash is finally put into activation furnace and activates 30min at 1000~1500 DEG C to get modified plant ash is arrived by wood ash.
In the present invention, as further explanation, the modified additive by by weight for 10~16:10~20:5~
8 machine oil fraction, silicone oil and turpentine oil mixes.
In the present invention, as further explanation, the anti-aging agent is antioxidant 264, antioxidant 4010 and anti-aging agent
One of 4010NA or a variety of.
In the present invention, as further explanation, the silicone oil is in methyl-silicone oil, ethyl silicon oil and phenyl silicone oil
It is one or more.
In the present invention, as further explanation, the machine oil fraction is prepared by the following method: by weight, will
80~100 DEG C are heated to after the sulfuric acid solution mixing that 100 parts of used oil and 30 parts of mass fractions are 12~15%, adds 20 parts
Carclazyte and 20 parts of magnetic patch stir 180~240min with the speed of 1500~2000r/min, stand 8h, extract the machine of upper layer purification
Oil is put into vacuum distillation apparatus, will be done after fractionating out lower than 390 DEG C of group, and will be left under conditions of pressure is 0.1atm
Fraction be machine oil fraction.
In the present invention, it as further explanation, a kind of preparation method of low temperature resistant asphalt waterproofing paint: presses
Weigh material according to the parts by weight of material each in composition of raw materials, pitch be first heated to 60~80 DEG C in a kettle, then plus
Enter modified additive, amylopectin, modified plant ash, natural rubber powder, anti-aging agent, sulphur powder, 2,6 1 di-tert-butyl cresols, charcoal
Black and talcum powder stirs 6~10min with the speed of 200~250r/min, then temperature is heated to 180~220 DEG C, with 300~
The speed of 400r/min stirs, and keeps 20min, and cooling discharging obtains low temperature resistant asphalt waterproofing paint.
The function introduction of part material is as follows:
Amylopectin, also known as amylopectin are a kind of polysaccharide of the molecule with dendritic branch structure, in the present invention, branch
Chain starch is used as a kind of tackifier, plays the role of the intensity for increasing coating.
Modified plant ash, by the modified plant ash powder of neutralization, in the present invention, the effect of modified plant ash is to use
Make filler and stabilizer, for adsorbing light component readily volatilized in coating, playing prevents light component from volatilizing and leading to coating
The effect of aging.

Silicone oil is a kind of polysiloxane of different polymerization degree chain structure, and in the present invention, silicone oil is the modification of pitch
Agent and machine oil fraction collective effect increase the resistance to low temperature of pitch.
The present invention has following beneficial effect:
1. the modified additive used in the present invention and modified plant ash can be obviously improved the resistance to low temperature of pitch and resist
Aging.Since the component of modified additive of the present invention is chain or ring molecule, molecular weight is relatively small, has
Viscous warm nature well, is affected by temperature very little, after mutually dispersion occurs with asphaltene molecule, can improve pitch in cryogenic conditions
It being hardened and becomes fragile, the problems such as cracking, after pitch and modified additive mutually disperse, obtained modified pitch is reduced with respect to paraffin content,
Light component also increases the flexibility of asphalt paint simultaneously, increases the resistance to low temperature of coating, still, since modification helps
Agent is the readily volatilized loss of light component substance, therefore, modified modified plant ash is introduced in the present invention, modified plant ash can rise
The holding capacity of light component into enhancing coating, after modified plant ash is distributed in pitch, since modified plant ash has very greatly
Kong Rong, in addition modified plant ash can effectively prevent the volatilization of light component to be lost the very strong adsorption capacity of modified additive, modification
The interaction of auxiliary agent and modified plant ash not only increases the resistance to low temperature of asphalt paint, and enhances the anti-of asphalt paint
Aging.
2. the preparation method of low temperature resistant asphalt waterproofing paint of the present invention, easy to operate, raw material sources are wide, production
Process environmental protection, pollution is few, takes full advantage of these wastes of used oil, rice straw, turns waste into wealth, increases its added value, solve simultaneously
The problem of waste of having determined processing.
