Description
Technical field
The present invention relates to a kind of diatomite water absorption pads and preparation method thereof, belong to water-absorbent material technical field.
Background technique
In Modern Family's life, the cushion of water imbibition is frequently with knitting chemical fibre class pad or towel.It is knitted chemical fibre class pad, is used
It is not easy afterwards dry, and is easily adhered dust, mould growth, bacterium and acarid etc., these concealments can generate different among the fibers
Taste needs to clean sunning often.Due to light weight, such as it is put on the ground people and is easy displacement in upper walking, without non-skid property, deposit
In security risk, it is not able to satisfy Modern Home dress to beautiful and texture requirement.
Plastic cushion mostly uses greatly the plastic cement such as PVC, silica gel to be made, and no water absorbing properties simultaneously contain halogen and plasticizer, resistance to
Heat and aging are poor, and plasticizer constantly migrates out product in use, and product, which is gradually hardened, deforms discoloration, service life
It is short, and dust is adsorbed, it is not easy sanitation and hygiene.Silica type pad is heat-resisting, ageing-resistant performance is fine, but without water absorbing properties, has water to spill
Shi Buneng absorbs in time, need to be wiped, and expensive using other methods, influence the popularization and use of product.
Diatomite is a kind of biogenic siliceous sedimentary rock, is mainly made of the remains of ancient times diatom, mainly at
It is divided into silica.Due to diatomite internal structure have many micropores and aperture it is big, diatomite have strong absorption
Performance and permeability can embody moisture absorption, the moisture absorption, eliminate peculiar smell, decomposing formaldehyde harmful substance, clean air, adjust space
The advantages that humidity, is a kind of very popular environment-friendly materials, is widely used in all trades and professions.Therefore, the present invention is ground emphatically
Study carefully, diatomite is applied to water absorption pad field, so that the water absorption pad has the characteristic of plastics and chemical fibre class pad simultaneously, it is existing to solve
There is knitting chemical fibre class pad easily to breed bacterium, not anti-skidding, plastics product is easily-deformable, discoloration, the defect not absorbed water.
Summary of the invention
For overcome the deficiencies in the prior art, the first purpose of this invention is to provide a kind of diatomite water absorption pad, should
Diatomite water absorption pad energy high-efficiency water-absorbing, and the harmful substance in air and adjustable air humidity can be removed, environmental protection and
It is at low cost, it is suitble to industrial production.
Achieving the object of the present invention can be reached by adopting the following technical scheme that:
A kind of diatomite water absorption pad, the raw material of the diatomite water absorption pad include: by weight
Preferably, the partial size of the diatomite is less than 50 microns.
More preferably, the partial size of diatomite is 25~45 microns.
Preferably, the inorganic mineral is at least one of zeolite, kaolin and calcium carbonate.
Preferably, the inorganic glue is one or both of gypsum, calcium hydroxide, white cement and waterglass.
Preferably, stating organic gel is water soluble acrylic acid glue.
Preferably, the retarder is citric acid.
Preferably, the auxiliary agent is at least one of water-reducing agent and defoaming agent.
The present invention, as main water suction and anti-biotic material, guarantees that product has quick water absorbing properties and antibacterial using diatomite
Property, using inorganic glue as main adhesives, organic gel as auxiliary bonding material, with guarantee product have good toughness and
Whole cohesiveness avoids product from picking phenomenon occur；Intensity is further increased as auxiliary reinforcement using glass fibre；It is logical
Cross addition auxiliary addition agent: retarder, defoaming agent, water-reducing agent etc. prepare technique, so that finished product is with corresponding processing
Performance.By preferably above-mentioned raw material, and by adjusting each component ratio, guarantee that product had not only had fine water absorbing properties, but also
Flexural strength with higher.
Second object of the present invention is to provide a kind of preparation method of above-mentioned diatomite water absorption pad.

Afterwards, water is added and is uniformly mixed, obtains diatomite mud；
2) diatomite mud is poured into mold, is then placed on bumper and shakes, and remove extra mud, dried
Roasting, demoulding obtains crude product；
The effect of vibration is so that the air between product pellet is squeezed out, the gap between reduction particle, so that finished product
Density is higher, preferred to shake the time for 5~10min；
3) crude product is polished, obtains diatomite water absorption pad；Crude product polishing is first to use the sand paper rough grinding of 800 mesh, then make
With the sand paper polishing surface of 1200 mesh and edge.
Be 50~55 DEG C in temperature preferably, in step 2), the time be 36-48h under conditions of carry out baking processing.
Compared with prior art, the beneficial effects of the present invention are:
1, diatomite water absorption pad of the invention, have relatively rich pore structure, intensity is good, flexural strength up to 3.0Mpa with
On, water absorbing capacity with super strength, saturated water absorption is up to 50.6%；
2, diatomite water absorption pad of the invention can play the effect of insect prevention, mould proof growth, the porous structure tool of diatomite
There is powerful adsorption cleaning performance, the harmful substance of air, peculiar smell can be adsorbed and be decomposed, play the work of air cleaning
With；
3, diatomite water absorption pad of the invention can promote that the evaporation of moisture, water absorption pad is restored at once in a very short period of time
Drying regime can be used for the dehumidifying, taste removal and deodorization of bathroom, shoe chest, wardrobe etc.；
