Description
Technical field
The present invention relates to the preparation method on Sound insulation floorings and this floor.The invention provides the floor with specific function, compare with conventional PVC floor, it has such as sound insulation value, impact absorbency, elasticity and anti-flexible excellent properties, thus the transmission sound between the floor, a whole set of apartment is reduced to minimum.
Background technology
Many patent specifications disclose the conventional sound insulation materials that utilizes useless fiber or tire debris to make, and for example Korean Patent is not examined open 1998-28832.According to this patent, will give up fiber or tire debris are directly sneaked in the concrete structure, perhaps they and adhesive are mixed and made into tile, reach soundproof effect above then this tile being layered on the concrete flat slab layer.Yet preceding a kind of method is about to the method that useless fiber or tire debris are directly sneaked into concrete structure, and is consuming time more, and considers that from the building structure technology aspect it needs a large amount of productivity.In addition, the crack might appear in construction back plastic surface.The problem of a kind of method in back is that other flooring material that is used to decorate must be installed after construction.
As other method, the panel material flexibly that can install such as carpet postpones to impact transmission.For this reason, this flexibly panel material should have excellent flexibility, and have big thickness, but can not guarantee enough durabilities, and this one of physical property of the basic necessity in floor just.In addition, be difficult to recover because flexible floor upper punch is hit the position, the first mate reduces the performance on this flexibility floor owing to the impact that repeats.In case flexible floor is out of shape owing to impacting, it will no longer absorb impact, therefore just impact be passed to the floor.
Sound insulation PVC can buy on market on the floor.Yet, because when forming the PVC foaming layer on PVC floor, used the mechanical foaming method (mechanically air to be injected PVC foaming colloidal sol, therefore gelation subsequently) replaced traditional chemical blowing method (mainly using Celogen Az), at other special equipment, poor efficiency with owing to just have problems aspect the high fabricating cost that low generation rate causes as CBA.In addition, owing to make the PVC floor have defective as the performance of the PVC inherence of raw material.
Summary of the invention
Among the present invention, utilize the chemical blowing method and do not use under the prerequisite of other special equipment to have formed foaming layer.For this reason, Corvic is mixed with crosslinked in advance acrylonitrile-butadiene-polyvinyl chloride copolymer resin and modified olefin resin form foaming layer.
Fig. 1 has illustrated the structure that is used for crosslinked in advance acrylonitrile-butadiene-polyvinyl chloride copolymer resin of the present invention.As shown in Figure 1, the acrylonitrile part in part of the butadiene in the rubber phase and the glassy phase is separated from one another.When copolymer resin when at room temperature being solid-state, acrylonitrile partly is used in the butadiene rubber part making copolymer resin have the performance of cross-linked elastomer as the physical crosslinking point.Glass transition temperature (the T that is higher than acrylonitrile when temperature
g, about 97 ℃) time, acrylonitrile partly is pliable and tough, so copolymer resin becomes fluid.Among the present invention, in copolymer resin, add as the divinylbenzene of crosslinking agent with as the mercaptobenzothiazoler of crosslinking accelerator and form the chemical crosslinking structure.At this moment, in order to improve the compatibility with polyvinyl chloride resin, the content of polyvinyl chloride monomer is adjusted to 9 weight %.The foaming layer of copolymer resin has partial cross-linked tridimensional network (being cross-linked structure), and the foaming layer of conventional Corvic is made up of 100% thermoplastic resin.Therefore, when described net structure is applied external impact, impact and transmit fast along net structure.At this moment, owing to there is not crosslinked part softer, therefore the impact that applies is partially absorbed by these and finally disappears.
Modified olefin resin used among the present invention is meant ionomer.This ionomer is because the interaction between the ion has strengthened the attraction between the polymer chain, and this attraction does not depend on chemical bond, has given polymer with cross-linking effect.As the used ionomer of the present invention, used Surlyn available from Dupont.Fig. 2 is the structural formula of ionomer.As shown in Figure 2, this ionomer has the copolymer structure of polyethylene and methacrylic acid.In order to make the ion characteristic maximization of ionomer, sneaked into metal cation such as Na or Zn ion.In view of the architectural feature of ionomer because it has high ion binding power, therefore fabulous formation the physical crosslinking structure so rather than chemical crosslinking structure.When cross-linked structure having been applied the external stress bigger than ion binding power (heat or impact energy), this structure is temporarily collapsed, and recovers subsequently.The mechanism of impact absorption is similar to above-described chemical crosslinking structure.
Because the foaming layer that forms in the inventive method has chemical crosslinking structure (tridimensional network) and physical crosslinking structure, so it has reached sound insulation value on the desired L-45 level of JIS technical specification.Except sound insulation value, this foaming layer also has excellent feel (walking feeling), impact absorbency and elasticity.In addition, also overcome the defective on conventional PVC floor, for example curled and tear.
Different with conventional sound insulation materials, because Sound insulation floorings of the present invention can not need to change the noise that the shape of concrete structure just can absorb and stop the daily life generation effectively by simple installation, so it makes the children can be freely mobile in doors.Particularly, when children fell down, floor of the present invention absorbs to be impacted, and has therefore protected child to preserve from.
According to an aspect of the present invention, the invention provides a kind of Sound insulation floorings, it comprises surface course, ground and back layer in order from end face, it is made with calendering process, wherein said surface course comprises from the bottom printed layers of lamination, hyaline layer and surface-treated layer in order, and described back layer comprises from end face middle resin layer, flexible foaming layer and the back side resin bed of lamination in order.
If desired, the printed layers or the surface-treated layer that are included in the surface course be can remove, middle resin layer or back side resin bed in the back layer perhaps are included in.In order to improve the sound insulation value of Sound insulation floorings of the present invention, surface course and back layer can be carried out embossing and be handled.
Like this, one or more layers in these layers is made up of crosslinked in advance acrylonitrile-butadiene-polyvinyl chloride copolymer resin.
According to a further aspect in the invention, provide a kind of preparation method of Sound insulation floorings, it comprises the steps:
A) mix Corvic, crosslinked acrylonitrile-butadiene-polyvinyl chloride copolymer resin (being called " NBR " hereinafter), modified olefin resin and TPU or ethylene vinyl acetate resin in advance, form the flexible foaming layer;
B) form hyaline layer, printed layers and middle resin layer;
C) dipping size reinforcement material forms the size enhancement Layer (dimension-reinforcing layer) of sol impregnation in polyvinyl chloride colloidal sol, and hot pressing size enhancement Layer forms the lamilated body of the size enhancement Layer of printed layers and sol impregnation to the printed layers;
D) at c) in printed layers and the lamilated body surface of the size enhancement Layer of sol impregnation on printed patterns;
