Description

The production technology of the permeable fragment of brick of composite sand base is prepared with casting mould antiquated sand
Technical field
The present invention relates to construction material manufacture field, it is more particularly related to which a kind of use casting mould antiquated sand system The production technology of the permeable fragment of brick of standby composite sand base.
Background technology
China is Metal casting producer, and annual antiquated sand generation total amount is huge.At present, except 20%~30% antiquated sand regenerates back With outer, most of this is not only greatly to waste to limited resource based on abandoning, and serious environment can be caused dirty Dye.Therefore, antiquated sand processing and using turn into China's foundary industry it is in the urgent need to address the problem of.On the one hand in ore resource In the case of increasingly in short supply, on the other hand can arbitrarily it be abandoned for reducing antiquated sand using cast waste sand as a kind of construction timber Caused public hazards are beneficial.Key process parameter is proposed by the development to the permeable fragment of brick of sand base and performance evaluation simultaneously Be advantageous to improve China's water-permeable brick research system, and accelerate to promote " sponge city " to build, have to alleviating water resources shortage situation Positive effect.
The content of the invention
Problem to be solved by this invention is to provide a kind of prepares the permeable fragment of brick of composite sand base with casting mould antiquated sand Production technology.With good environmental benefit, reduce antiquated sand processing cost, and hydrostatic profile technique compares vibration moulding, The fragment of brick prepared has higher permeability rate.
To achieve these goals, the technical scheme taken of the present invention is：
The production technology that the permeable fragment of brick of composite sand base is prepared with casting mould antiquated sand comprises the following steps：
(1) antiquated sand pre-processes：Cast waste sand is sieved with screen cloth, and sand in sand particles grading II areas；
(2) mix：Surface material first weighs above-mentioned cast waste sand, epoxy resin by pretreatment in proportion (GCC135), curing agent (GCC137), then GCC137 and GCC135 is put into planet glue sand agitator and are stirred mixing 5min, it is subsequently added into the antiquated sand weighed and continues to be stirred 7~15min, obtain epoxy resin mortar；Base material press than Example weighs rubble, cement, clear water.It is stirred after 10% water is added into rubble, makes rubble surface uniform wet, is then added Enter cement mixing 2min (making cement uniformly be wrapped in aggregate surface), basic unit's material is obtained after being eventually adding remaining water stirring 2min Material；
(3) mould is inserted：Base material is injected in stainless steel mould after being consolidated, surface material is injected, with repairing knife Smooth out surface, and stainless steel cover plate is covered, surface material thickness is 5~10mm；
(4) hydrostatic profile：Mould is placed on forcing press, hydrostatic profile, the time is 60~90s.Pressure size is 2MPa；
(5) it is stripped：Mould is moved away from into forcing press, stands 24h, adobe and the separation of mould is carried out, obtains composite sand base Permeable fragment of brick；
(6) after being stripped 72h, concrete intensifier is sprayed to fragment of brick, sprays 1 time every 24h, sprays 2 times altogether；
(7) natural curing：To the permeable fragment of brick of composite sand base natural curing at normal temperatures 25 days, temperature was 20~30 DEG C.
Preferably, step (2) the epoxy resin concentration is 2~8%, and the ratio of epoxy resin and curing agent is 3: 1.
Preferably, step (2) the medium stone particle diameter is 2.5~10mm, and cement is P.O 42.5, and gelatine ratio is 4~5, The ratio of mud is 0.25~0.35.
Beneficial effect：The surface material of the permeable fragment of brick mainly uses casting mould antiquated sand, and its reasonable utilization can be reduced The waste of social resources.The manufactured permeable fragment of brick of entire body resin sand base is a kind of new green structural material, it is developed and Performance evaluation is advantageous to improve China's water-permeable brick research system, be follow-up sand base water-permeable brick industrialization prepare propose feasibility and Key process parameter.Antiquated sand is after adhesive solidifies, some heavy metal ion (such as As3+、Hg2+、Cd2+Deng) tending towards stability, make Obtaining the water-permeable brick has good environmental benefit, reduces antiquated sand processing cost.Compared to entire body resin sand base water-permeable brick, its cost Substantially reduce, the permeable fragment of brick of composite sand base has certain cost advantage.Hydrostatic profile technique compares vibration moulding, prepares Fragment of brick has higher permeability rate.Hydrostatic profile technique is easy to mass produce, beneficial to the shaping of fragment of brick.
