It is made up by using waste polyurethane and waste polypropylene fibre as aggregate, and mixing them with chemical raw materials of acrylic acid emulsion, sodium hexametaphosphate, sodium benzoate, ethylene glycol, propylene glycol, polydimethylsiloxane, methyl cellulose, calcium carbonate and colouring agent according to a certain mixing ratio.
Description
Technical field
The invention belongs to building material technical field, be specifically related to a kind of waste polyurethane and useless fiber production building pointing and preparation method thereof of utilizing.
Background technology
Along with the fast development of urban construction and environmental protection, need to call various energy-conserving and environment-protective energy saving building materials.The urethane wall heat insulation material was because its outstanding comprehensive physicochemical property more and more widely was applied to energy-conservation lagging material in recent years.Yet a large amount of polyurethane waste materials have caused new environmental pollution again, also occur new utilized industrial waste resource simultaneously; In addition, various man-made fiber have also become the resource of urban construction; Because a lot of novel energy-conserving building materials are applied, and need more supplementary material common combination, become easy to use and the perfect performance application system.
Moreover some novel wall material of construction are often run into the defective of splicing seams, shrinkage joint, adopt energy-saving material to the outer insulation of metope and heat insulation etc., all need novel building pointing fit applications.
In sum, research a kind of have functional, can joint filling, to strengthen, can resist fissured environment protection multifunctional reinforced composite be those skilled in the art's goal in research.
Summary of the invention
The objective of the invention is to propose a kind ofly has well attached ability, intensity to utilize waste polyurethane and useless fiber production building pointing and preparation method thereof preferably.
The present invention proposes utilizes waste polyurethane and useless fiber production building pointing, is to be that main raw material adds batching and forms with waste polyurethane material and waste and old man-made fiber, and the weight percent of its component is:
Waste polyurethane powder 20-25%
Waste and old polypropylene fiber 5-8%
ACRYLIC EMULSION 40-45%
Sodium hexametaphosphate 99 4-5%

Polydimethylsiloxane 0.05-0.06%
Lime carbonate 15-20%
Methylcellulose gum 1.5-2%
All the other are water,
Its weight satisfies 100%.
Among the present invention, described waste polyurethane powder directly is the 60-80 order.
Among the present invention, described waste and old polypropylene fiber length is 3-5mm.Selecting for use also of fiber can be according to the color of body of wall, or is formed with special lathe work and variegated style.
Among the present invention, can also add tinting material in pointing, its consumption is the 0.07-0.1% of pointing gross weight, the color of tinting material should select for use can be as far as possible with the color of filling out building wall be same system.
The preparation method who utilizes waste polyurethane and useless fiber production building pointing that the present invention proposes, its concrete steps are as follows:
Part by weight by each component, measure each component, earlier waste polyurethane powder, polypropylene fiber and lime carbonate are mixed as component A, again ACRYLIC EMULSION, Sodium hexametaphosphate 99, Sodium Benzoate, ethylene glycol, propylene glycol, methylcellulose gum, tinting material are mixed as B component, then component A and B component are mixed, add polydimethylsiloxane, water at last, stir, promptly get desired product.
Among the present invention, the waste polyurethane powder is that trade wastes such as the scrap stock pulverizing of waste polyurethane goods or polyurethane building lagging material obtains, or for obtaining after the treated pulverizing of spontaneous scrap stock in the polyurethane product course of processing, be uniform fine particulate object, the rubber powder particle diameter that this pointing adopts is about about 80 orders; The used fiber of the present invention is that the trade waste of chemical fibre source mill is cut into the following length specification of 5mm after treatment, perhaps can directly buy the product of this specification from market.
The matrix material that the present invention proposes has good physicochemical property.Press GB through appropriate authority and detect performance such as following table:
| Title | Conditioned disjunction unit | Performance |
| Surface drying time | H | 2h-2.5h |
| Water tolerance | 48h | The no bubble in surface, slight crack, obscission |
| Alkali resistance | 48h, saturated aqua calcis | The no bubble in surface |
| Abrasion resistance | 500 times | Do not have and destroy |
| Adhesion strength | MPa | 0.5-0.58 |
| Winter hardiness | -40C，24h | No change |
| Thermotolerance | 80C，24h | No change |
| Tensile strength | MPa | 1.5 |
| Elongation at break | /％ | 25 |
| Shear bonding strength | MPa | 0.5 |
The present invention is main aggregate owing to having used the waste polyurethane products waste, has improved economic worth greatly, and product itself also has good physicochemical property.The available special spray gun spraying of constructing also can be scraped and be smeared, and need not that other adhesive can satisfy the joint filling requirement and cost is low.
Material of the present invention can be used for various metopes, also can be used for slits such as post, plate fills up.Owing to be water-based environment-friendly,, do not have newly and pollute at making, construction, nontoxic, the odorlessness of prolonged application process.
