Background
China is a big country for floor production and consumption, and the demand of the solid wood floor is continuously increased due to other advantages such as natural environment protection and the like. However, the development of solid wood as a non-renewable resource in a short period is obviously limited, and many countries have instructed that trees are prohibited from being felled, which causes the price of upstream raw materials to rise year by year, so that the research and development of new materials for synthesizing floors become problems to be solved urgently in the floor industry of China.
Currently, synthetic flooring is mainly composed of solid wood composite flooring, PVC flooring, and the like. The composite solid wood floor is a derivative of the solid wood floor, so the composite solid wood floor is widely welcomed by people, but the adhesive adopted by the composite solid wood releases certain formaldehyde and other solvents, so the composite solid wood floor with higher real environmental protection level is expensive, and people are difficult to identify and select when selecting the composite solid wood floor. The synthetic floor is produced, more choices are provided for people, PVC (polyvinyl chloride) floors in the existing synthetic floor are common, the environmental protection level of plates is higher, and the raw material polyvinyl chloride is an environment-friendly and nontoxic renewable resource and is widely popular all over the world. However, the common PVC floor is mostly constructed on site by using adhesives, or the PVC floor precoated with gum needs to be constructed after the release paper is torn off, and the construction process is complicated. In addition, the traditional PVC floor is directly contacted with a hard ground, so that the foot feeling and the floor noise are also certain problems, but the laying of the sound-insulation and noise-reduction material and then the laying of the PVC floor are difficult in actual construction.
Therefore, how to pre-compound the sound-insulation and noise-reduction material with the PVC floor, so as to improve the construction operability, improve the laying efficiency, and maintain the original environmental protection characteristic of the PVC floor becomes a new research topic.

No other waste products are produced in the construction process, no solvent volatilization or other waste is produced in the construction process and after the construction, and the paint can be directly used.
Verification examples
In this verification example, the glue for compounding the sound-insulating and noise-reducing material and the PVC floor provided in the first to third embodiments was subjected to apparent viscosity, softening point test and appearance test (test results are shown in table 1), and the following methods were used:
1. viscosity of the oil
Viscosity is a viscous property of liquid which generates internal friction between molecules when flowing, and the viscosity is expressed by viscosity and is used for characterizing a resistance factor related to the liquid property. The unit is Pa.s, and the characteristic is that the area of the two blocks is 1m2The plate of (a) is immersed in a liquid,the distance between the plates was 1m, and when a shear stress of 1N was applied to the plates so that the relative velocity between the plates was 1 m/sec, the viscosity of the liquid was 1Pa · s, and 1000mPa · s was 1000 cps.
With reference to the determination of the melt viscosity of the hot-melt adhesive "HG/T3660-1999, a Brookfield DV-2+ PRO type rotary viscometer was used for the test, comprising the following steps:
(1) sample preparation: a sample of the sound-insulating and noise-reducing material with the weight of 10.5g +0.5g and the glue for compounding the PVC floor is taken.
(2) The method comprises the following operation steps:
I) selecting the related setting of the No. 27 rotor, and setting the temperature to be 180 ℃;
selecting a proper same rotor for the same sample and putting the weighed sample into a sample groove;
II) after the temperature reaches 180 ℃, vertically immersing the rotor into the central part of the sample, and enabling the liquid level to reach a rotor liquid level marking (a protection frame is arranged);
III) starting a rotational viscometer, and adjusting the rotating speed according to the actual viscosity change to ensure that the reading on the display screen can test the viscosity data within the range of 20-80% under the current rotating speed condition;
IV) reading when the value of the display screen is kept unchanged to obtain the viscosity data of the product;
v) three determinations per sample.
2. Softening point
The softening point is not the melting point, the softening point is not the phase transition process, it is the process by which the polymer decreases from a high viscosity to a specific viscosity, the softening point being characterized by a temperature range. In the hot melt adhesive industry, the softening point test method refers to GB/T15332-94 determination of the softening point of the hot melt adhesive Ring and ball method. The specific test steps are as follows:
I) melting the rubber sample to be detected and filling the rubber sample into the sample ring;
II) scraping off excessive samples on the sample ring by using a scraper so that the samples are flush with the ring surface;
III) cooling the sample for 24 hours at room temperature;
IV) then placing a sample ring filled with the sample, a steel ball positioning ring and a steel ball on the metal bracket in sequence;
v) placing the metal bracket in a glycerol bath with the heating rate of 5 ℃/min;
VI) opening the automatic softening point tester, and starting stirring;
VII) along with the rise of the temperature of the glycerol, the sample begins to soften until the softening point data is automatically recorded by an instrument in the process that the steel ball falls to the lower bearing plate;
VIII) printing the test result;
IX) test results of the final softening point were averaged over 3 samples.
3. Appearance detection
The method mainly adopts a mode of establishing standard sample comparison by visual inspection, samples with the same packaging specification are compared in color and transparency, and the standard sample needs to be established for the first production.
