Abstract
The invention relates to a method for producing crack-resistant and seepage-proof fibers by using waste and old polypropylene, and aims to provide a method for producing crack-resistant fibers by taking waste and old recycled polypropylene as a raw material and adding an additive to further improve performance during preparation. According to the technical scheme for fulfilling the aim, the method for producing the crack-resistant and seepage-proof fibers by using the waste and old polypropylene comprises the following steps of: (a), crushing the recycled waste and old polypropylene into cylindrical crushed materials; (b), adding the additive which consists of a preservative, a reinforcing agent and a toughening agent into the cylindrical crushed materials; (c), melting at the temperature of 200 DEG C, and performing extrusion molding by an injection molding machine; (d), performing wiredrawing in a die to form a threaded shape, and cooling for forming; (e), after water cooling, heating by using hot water at the temperature of 100 DEG C; and (f), leading wires out by using a guiding wheel, crushing and cutting. The method can be widely applicable to engineering of the water prevention of underground engineering, roofs, walls and the like of industrial and civil constructional engineering, roads, bridges and the like.
Description
Technical field
The present invention relates to a kind of construction material, be specially a kind of method that waste and old polypropylene produces anti-crack and anti-seepage fiber.
Background technology
If polypropylene fibre acid and alkali-resistance thermal conductivity, has extremely stable chemical property.Add in mortar or concrete and can effectively control in mortar, the concrete plastic shrinkage stage in the early stage due to microcrack that the factors such as variations in temperature cause, formation and the development in crack prevented and suppressed, concrete anti-cracking impervious performance, shock resistance and shock resistance greatly improved.
Current polypropylene fibre is that Raw material processing is produced usually with acrylic resin, and cost is high, price; On the other hand, in existing production technology, there are no developing by adding additive, and by each component synergy of additive, promote the method for polypropylene fiber concrete performance further.
Summary of the invention
The object of this invention is to provide that one utilizes waste and old recovery polypropylene as raw material, reduces costs, low-carbon environment-friendly, and by adding the anti-crack fiber production method that additive promotes polypropylene fiber concrete performance further in preparation.
The object of the invention is to adopt following technical proposals to realize: the method for producing anti-crack and anti-seepage fiber with waste and old polypropylene, it comprises following operation:
A. the waste and old polypropylene of recovery is ground into column;
B. the additive be made up of preservative agent, reinforcing agent, flexibilizer removal of impurities is added in column comminution of material;
C. melt at 200 DEG C, by injection machine extrusion molding;
D. enter mould wire drawing and become screw-like, shaping cooling;
E. after water-cooled, then 100 DEG C of hot water intensifications are entered;
F. by directive wheel, silk is derived, pulverize cutting, obtain product.
Wherein additive described in step b by preservative agent, reinforcing agent, flexibilizer according to the proportions of weight ratio 1:1:1.
Produce the method for anti-crack and anti-seepage fiber with waste and old polypropylene, comprise following operation:
A. the waste and old polypropylene of recovery is ground into column;
B. the additive be made up of preservative agent, reinforcing agent, flexibilizer and cleaner is added in column comminution of material;
C. melt at 200 DEG C, by injection machine extrusion molding;
D. enter mould wire drawing and become screw-like, shaping cooling;
E. after water-cooled, then 100 DEG C of hot water intensifications are entered;
F. by directive wheel, silk is derived, pulverize cutting, obtain product.The silk produced is than former particle reinforce about 10%.Step b adds cleaner, and cleaner refines the impurity such as dust, automatically precipitates, to remove dust.
Wherein additive described in step b by preservative agent, reinforcing agent, flexibilizer, cleaner according to the proportions of weight ratio 1:1:1:1.
Above-mentioned steps b additive additional proportion is, according to weight ratio column comminution of material: additive is 9:1.
Beneficial effect of the present invention is according to known to describing of such scheme: utilize and recycle the waste as raw material, low-carbon environment-friendly, low production cost; By adding the additive be made up of preservative agent, reinforcing agent, flexibilizer removal of impurities, promote fiber concrete mechanical property, endurance quality, fire protecting performance and anti-seismic performance further; The anti-crack and anti-seepage fiber prepared with this method, can be applicable to underground project waterproof widely, the roofing of industrial civil building engineering, body of wall, terrace, pond, basement, and in the engineering such as road and bridge.
