Abstract
The invention discloses a waterproof and root-resistant polyurethane coating for planting roof, which is prepared by uniformly mixing a component A with a component B according to a mass ratio of 2:1, wherein the raw material of the component A is a polyurethane prepolymer; the raw material of the component B is composed of the following ingredients in parts by weight: 30-35 parts of curing agent, 28-32 parts of liquid filler, 11-15 parts of talcum powder, 11-14 parts of barium sulfate, 5-8 parts of titanium pigment, 2-4 parts of dispersant, 1-2 parts of defoaming agent and 1-2 parts of chemical root resistance agent. By means of the synergistic effect of the chemical root resistance agent, the polyurethane prepolymer, and the like, the root resistance effect of the polyurethane coating is good and the waterproof performance of the polyurethane coating is greatly improved. The polyurethane coating disclosed by the invention can be used for realizing seamless connection of the waterproof layer of the whole planting roof to form a skin type waterproof and excellent root resistant effect, and the polyurethane coating has such excellent performance as simple construction, short drying time, high adhesive strength with a base layer, and good waterproof and root resistant effect.
Description
One, technical field
The present invention relates to a kind of functional urethane coating, specifically a kind of waterproof for planted roof, root resistance polyurethane coating.
Two, background technology
Along with the raising gradually of economic fast development and people's living standard, energy dilemma and ecocrisis are more and more severeer, and the buildings comsumption of natural resources person maximum as society is very serious to environmental influence.Roof greening can improve urban air-quality, alleviates tropical island effect, promote the urban air view; Roof greening can also be built the ecosystem of making us pleasing, beautifying the environment in addition.But, because the plant of surface grafting has flourishing root system, they can penetrate roof construction layer and cause serious percolating water phenomenon, so also to there is anti-roots of plants when roof greening engine request waterproof and wear performance.
At present planted roof all adopts coiled material to carry out waterproof and root resistance, but the series of problems such as waterproof roll exists overlap joint not firm gap to be arranged, special-shaped part is difficult and bonding effect is poor, thereby cause waterproof roll can not reach good waterproof root resistance effect.
CN10286389A discloses a kind of waterproof paint of anti-the plant root puncture, two portions, consists of, and the first component is the polyethers performed polymer that contains the cyanamide root, and the second component is mixture and the chemical root resistance agent that contains hydroxyl, amino group.The first component and the second component ratio of mixture are 1:2-3, and this waterproof paint is easy to use bonding firmly with substrate, and has fine use value and economic benefit.
CN102965020A discloses anti-spraying rapid hardening rubber asphalt waterproof coating for a kind of plantation, this waterproof paint is adopted new technology emulsified bitumen and polymer rubber latex is mixed in proportion and is made into liquid latex and adds the root resistance agent in liquid latex, then with condensing agent, is mixed in proportion and makes a kind of water-based paint.This coating has that elongation at break is high, cohesive strength is large, ageing-resistant, UV resistant environment-protecting asepsis have good root resistance effect, is widely used in various planted roof waterproof.
It is convenient that polyurethane water-proof paint is not only constructed, can be regarded as real skin-type waterproof, nor there is the not firm and poor problem of bonding effect that overlaps, therefore polyurethane water-proof paint can be modified into to the waterproof paint of anti-plant root puncture, make it reach good root resistance effect in waterproof.The special-purpose polyurethane water-proof paint of planted roof have not been reported in addition.
Three, summary of the invention
The present invention aims to provide a kind of waterproof for planted roof, root resistance polyurethane coating, and technical problem to be solved is to select suitable raw material, auxiliary agent and proportioning to make polyurethane coating possess anti-roots of plants when having good water resistance to wear performance.
Technical solution problem of the present invention adopts following technical scheme:
The present invention is for waterproof, the root resistance polyurethane coating of planted roof, by component A and B component in mass ratio the ratio of 2:1 mix and obtain;
The raw material of described component A is polyurethane prepolymer;
The raw material of described B component is configured to by mass fraction:
Described solidifying agent is polyethers N-220 or polyethers N-330.
Described liquid filler is liquid petroleum resin or Viscotrol C.
Described dispersion agent is BYK-190, BYK-163 or BYK-110.
Described defoamer is BYK-052, BYK-063 or BYK-066N.
Described chemical root resistance agent is chemical root resistance agent B2 or B5, and by bright Sheng, chemical (China) company limited produces.
Described component A stirs polyurethane prepolymer to obtain.
Described B component is that dispersion agent, defoamer and liquid filler are added in reactor, is uniformly mixed, and adds solidifying agent, talcum powder, barium sulfate and titanium dioxide under stirring, after ground and mixed is even, adds chemical root resistance agent, is uniformly dispersed and gets final product.
Polyurethane prepolymer of the present invention is commercial, SD1235, BT1245 or B1262 that preferably Shanghai Dongda Chemical Co., Ltd. produces.
The concrete preparation process of polyurethane coating of the present invention is as follows:
1) polyurethane prepolymer is stirred and obtain component A;
2) dispersion agent, defoamer and liquid filler are added in reactor, are uniformly mixed, add solidifying agent, talcum powder, barium sulfate and titanium dioxide under stirring, after ground and mixed is even, add chemical root resistance agent, after being uniformly dispersed, obtain B component;
3) use before by component A and B component the ratio mixing and stirring according to mass ratio 2:1, brushing, roller coat or be sprayed at planted roof and get final product.
The present invention, by the synergistic effect of chemical root resistance agent and polyurethane prepolymer etc., has realized that polyurethane coating is when having good root resistance effect, aspect water resistance, also improves a lot.Although solved that existing polyurethane coating has certain elongation at break and tensile strength but the problem that do not have good root resistance effect has realized that polyurethane water-proof paint also has good chemical root resistance when having excellent waterproof effect.Realized the perfect adaptation of waterproof and root resistance.This coating has that preparation technology is simple, raw material is easy to get and the characteristics of stable performance in addition, is applicable to large-scale industrial production.
