Abstract
The invention discloses a method for producing constructional tiles by using waste and old PE and fly ash. The constructional tiles comprise, by weight, 30-50 parts of waste and old PE particles, 40-55 parts of fly ash, 3-5 parts of graphite, 5-7 parts of active titanium dioxide and 3-5 parts of solid paraffin. The method comprises the following steps: preparing the above components, putting the components in a stirrer, uniformly mixing, carrying out extruding granulation through a fusion technology, putting extruded particles in a die, carrying out cold pressing, heating, carrying out hot pressing at 140-150DEG C under 130-140MPa, cooling to 60DEG C or less, and demolding to make the tiles. The constructional tiles produced through the method have the advantages of low cost, economy, environmental protection, low water absorption and high tensile strength.
Description
Technical field
The invention belongs to building material technical field, particularly relate to the method utilizing waste and old PE and flyash to produce construction tile.
Background technology
Along with the development of economy, building becomes the large mainstay industry of China one, thus driven construction timber field fast development, make construction tile industry competition more and more fierce.In recent years, China's strategy of sustainable development has goed deep into each large industry field, and building field also advocates low-carbon (LC), environmental protection, energy-conservation use material, and corresponding construction tile is also towards the future development of environmental protection and energy saving.
At present, the white pollution that waste or used plastics causes becomes the concomitant problem in the world, and countries in the world are all being explored for solving white pollution, and achieve certain effect, recycle the effective ways that waste or used plastics can solve white pollution, also can produce economic benefit.Therefore, the recycling of plastics becomes current a kind of hot issue, has bibliographical information, waste and old PE particulate material can be utilized to produce construction tile, but the method for this report adopts CaCO
3as the properties-correcting agent of tensile strength, although add the tensile strength of correlated product, still have greatly improved space.
Based on the feature of the problems referred to above and corresponding property-modifying additive, the invention provides a kind of method utilizing waste and old PE and flyash to produce construction tile, the object improving white pollution can be realized, also realize high tensile strength and the low water absorption of construction tile.
Summary of the invention
The object of the invention is to: a kind of method utilizing waste and old PE and flyash to produce construction tile is provided, waste and old PE plastic grain material and flyash is adopted to be main raw material, by active titanium dioxide modification, the construction tile tensile strength obtained is significantly improved, also the method by adding paraffin reduces the water-intake rate of goods further, realizes the high dominance energy of construction tile.
To achieve these goals, the present invention adopts following technical scheme:
Utilize waste and old PE and flyash to produce the method for construction tile, it is characterized in that this construction tile (with parts by weight) comprises following component:
Get the raw materials ready according to said components, then stirrer for mixing is put it into even, adopt scorification extruding pelletization, again the particle extruded is put into mould, cold pressing, heat, it is 140 ~ 150 DEG C that hot pressing temperature controls, and hot pressing pressure is 130 ~ 140MPa, is cooled to 60 DEG C can make watt goods with bottom knockout.
With existing building with watt compared with, beneficial effect of the present invention is:
(1) adopt waste and old PE particulate material and flyash to be main raw material, production cost is low, high financial profit, and environmental protection and energy saving;
(2) adopt active titanium dioxide to substitute in prior art use CaCO
3properties-correcting agent, makes watt goods tensile strength higher;
(3) add solid paraffin components in formula, increase the water-repellancy of watt goods, reduce water-intake rate, when avoiding rainy, construction tile absorbs water and causes weight to strengthen, and causes house to bear larger weight.
Embodiment
Below in conjunction with specific examples, technical scheme of the present invention is described further, but does not limit the change of selecting materials of the present invention program.
Example 1
Utilize waste and old PE and flyash to produce the method for construction tile, it is characterized in that this construction tile (with parts by weight) comprises following component:
Get the raw materials ready according to said components, then put it into stirrer for mixing even, adopt scorification extruding pelletization, again the particle extruded put into mould, cold pressing, heat, it is 140 DEG C that hot pressing temperature controls, hot pressing pressure is 130MPa, is cooled to 60 DEG C can make watt goods with bottom knockout.
Wherein, the JS series biaxial rneader that described stirrer adopts effluent Nan Zhongda heavy industry Science and Technology Ltd. to produce; Extruding granulator adopts the twin screw extruder produced by Dongguan City Yongfeng rubber and plastics machine Science and Technology Ltd., and extrusion temperature is 145 DEG C.
Example 2
Utilize waste and old PE and flyash to produce the method for construction tile, it is characterized in that this construction tile (with parts by weight) comprises following component:
Get the raw materials ready according to said components, then put it into stirrer for mixing even, adopt scorification extruding pelletization, again the particle extruded put into mould, cold pressing, heat, it is 145 DEG C that hot pressing temperature controls, hot pressing pressure is 135MPa, is cooled to 60 DEG C can make watt goods with bottom knockout.
Described machinery equipment is with example 1.
Example 3
Utilize waste and old PE and flyash to produce the method for construction tile, it is characterized in that this construction tile (with parts by weight) comprises following component:
Get the raw materials ready according to said components, then put it into stirrer for mixing even, adopt scorification extruding pelletization, again the particle extruded put into mould, cold pressing, heat, it is 150 DEG C that hot pressing temperature controls, hot pressing pressure is 140MPa, is cooled to 60 DEG C can make watt goods with bottom knockout.
Mechanical means used is with example 1.
By the construction tile that technical solution of the present invention is produced, tensile strength is large, and notched Izod impact strength is high, than traditional CaCO
3the construction tile that the PE of modification makes improves nearly one times, and water-intake rate obviously lowers.
