Abstract
The present invention belongs to the field of building material technology, in the concrete, it relates to a flexible acrylic acid waste polyurethane water-base composite joint-filling material and its preparation method. It is made up by using powder obtained by processing waste polyurethane material as aggregate and mixing it with the chemical raw materials of acrylic acid elastic 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 flexible acrylic acid waste polyurethane water composite joint filling material and preparation method thereof.
Background technology
The fast development of environment protection need be called 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, along with because a lot of novel energy-conserving building materials are applied, need a lot of supplementary material common combinations to become easy to use and the perfect performance application system.Some novel wall material of construction are often run into behind splicing seams, shrinkage joint, the employing energy-saving material outer insulation of metope and the novel building pointing fit applications that all needs such as heat insulation.The environment protection multifunctional matrix material that market is a long felt need for is functional, can joint filling.
Summary of the invention
The objective of the invention is to propose a kind ofly has adhesive ability, a kind of flexible acrylic acid waste polyurethane water composite joint filling material of better intensity and other over-all propertieies and preparation method thereof is arranged.
A kind of flexible acrylic acid waste polyurethane water composite joint filling material that the present invention proposes is that main filler aggregate raw material adds the batching composition with the depleted polyurethane material, and the heavy per-cent of its component is:
Waste polyurethane powder 25-35%
Acrylic elastic emulsion 40-45%
Sodium hexametaphosphate 99 04-0.5%
Sodium Benzoate 0.4-0.5%
Ethylene glycol 0.7-0.9%
Propylene glycol 2-3%
Polydimethylsiloxane 0.04-0.05%
Lime carbonate 15-20%
Methylcellulose gum 1.5-2%
All the other are water,
Its total amount satisfies 100%.
Among the present invention, described waste polyurethane powder directly is the 60-80 order.
Among the present invention, also can add tinting material, its add-on is the 0.06-0.1% 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 of the flexible acrylic acid waste polyurethane water composite joint filling material that the present invention proposes, concrete steps are as follows:
Take by weighing various raw materials by component ratio, earlier waste polyurethane powder and lime carbonate are mixed, as component A, again ACRYLIC EMULSION, Sodium hexametaphosphate 99, Sodium Benzoate, propylene glycol, methylcellulose gum, tinting material are mixed, as B component, then that A, B two component blending dispersion is even, at last, add polydimethylsiloxane, water, stir, promptly get desired product.
Waste polyurethane powder among the present invention 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 80 orders.
The pointing 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 | 0.5-0.52 |
| Winter hardiness | -40C，24h | No change |
| Thermotolerance | 80C，24h | No change |
| Tensile strength | MPa | 1.1 |
| Elongation at break | /％ | 216 |
| Shear bonding strength | MPa | 0.40 |
The present invention is main aggregate owing to having used the waste of waste polyurethane goods, 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.
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.
