Description
Technical field
The present invention relates to latch floor technical fields, and in particular to a kind of for the middle material of latch floor and its preparation side
Method.
Background technique
Latch floor is tightly combined, and overcomes most of floors by extraneous cold and hot dry and wet change procedure, the off-seam of generation,
Warpage plays the problems such as drum, in pavement process, thoroughly exempts to follow closely, exempts from glue, exempts from keel, be directly layed in ground, save room height
Degree, and dismounting can be repeated and utilized, it is economical and practical.
The advantages of latch floor, is many, and type is also very much, the reason more than type be many latch floor manufacturing enterprises in order to
Advantageous advantage is occupied in market competition and has applied for patent, forces other laminated flooring manufacturing enterprises in various degree to lock
Technology improves.It is reported that declares latch floor patent in the world at present has as many as 17.
Latch floor maximum feature is to prevent floor gap from cracking.Floor lock button it is secured, stable, persistently, essentially consist in
The chamfering area and angle and machining accuracy of lock, what the factors such as substrate toughness determined.As long as single fastener is structurally reasonable,
It is enough to prevent the cracking of floor gap.Multiple areas for latching in chamfering and angle are possible to that ideal indicator is not achieved, such
As a result it may run counter to desire.
In existing PVC plastic adhesive floor formula, in order to control the expansion rate and shrinking percentage of product, it joined a large amount of inorganic
Filler (calcium carbonate), and increase filler material as far as possible to control expansion rate and shrinking percentage.Its major defect: a large amount of nothing is added
After machine filler (calcium carbonate), density, hardness can increase with the increase of inorganic filler, and toughness can then decline, i.e. product
Edge can become fragile, and easily cause damage in processing and transportational process.
A kind of middle material and preparation method thereof for latch floor is disclosed in Chinese patent CN104109321A at present,
The middle bed of material be made of the raw material of following parts by weight: 100-200 parts of polyvinyl chloride, 1-5 parts of stabilizer, 20-40 parts of plasticizer, charcoal
It is 0.1-1 parts black, 400-600 parts of calcium carbonate, 5-10 parts of nitrile rubber.The invention is increasing nothing in the method for preparing middle material
In the case where machine filler, using nitrile rubber is added, convenient mill processing while improving the toughness of middle material, is gone back
Improve the intensity that pulling force is latched between product.Compared with existing plastic floor, the middle material and wearing layer of invention preparation, print
The flooring product obtained after the color film of brush, underlying material heat are compound has intensity, heat resistance, cold resistance.
A kind of composite floor board middle material that thermal stability is excellent is disclosed in Chinese patent CN104130521A at present, it by
PVC, plasticizer, stabilizer, calcium carbonate and coupling agent composition, the preparation method of the excellent composite floor board middle material of thermal stability, the
One step dilutes coupling agent；Second step is blended with inorganic filler；Third step, the calcium carbonate that second step has been mixed be added to PVC,
Plasticizer, stabilizer three mixed powder in；4th step, mill.The composite floor board middle material as made from this method has heat
Stability is superior, and expansion rate reaches 0.065%, and shrinking percentage reaches 0.03%；Simultaneously using titanate coupling agent and thermopolymer,
Calcium carbonate has good coupling effect, is combined both calcium carbonate and PVC by chemical action, so that it is guaranteed that the heat of size
Stability.
A kind of middle material of the composite floor board of tenacity excellent is disclosed in Chinese patent CN104130520A at present, it is by matter
Measure number are as follows: PVC100 parts, 36 parts of plasticizer, 2 parts of stabilizer, 510.6 parts of calcium carbonate, 7 parts of groups of nitrile rubber containing acrylonitrile
At；The content of acrylonitrile is 31-35% in the nitrile rubber；The preparation method of the middle material of the composite floor board of tenacity excellent,
The PVC powder of formula ratio, plasticizer, stabilizer are placed in mixing apparatus and are mixed 15 minutes；After adding calcium carbonate
It is mixed 15 minutes again, it is made to be sufficiently stirred, be uniformly mixed；Nitrile rubber is finally added, 15 points are mixed again
Clock, so material is uniformly mixed.The shrinking percentage of the middle material of the composite floor board obtained by this method is less than or equal to
0.03%, expansion rate is less than or equal to 0.1%, and its hardness can reach 65 °.
But the middle material of latch floor limited, the lower defect of strong hardness that usually there is toughness in the prior art.
