The sound insulation material in the floating floor slab is XPE IXPE foam material, and its production process is as follows: 1. According to a certain ratio of raw materials such as PE, masterbatch particles are produced by the kneading and granulating unit of the XPE IXPE Foam machine line. 2. After mixing the PE and the master batch produced in the first step according to another formula, the master sheet is produced by the master sheet extruding unit of the XPE IXPE Foam machine line. If DCP is added in this step, XPE foam material is produced, and the third step can be directly skipped into the foaming machine for foaming process. 3. The master sheet produced in the second step is subjected to the cross-linking process through the irradiation unit of the XPE IXPE Foam machine line. 4. The DCP-added master sheet or the irradiated master sheet is foamed through the foaming machine unit of the XPE IXPE Foam machine line to obtain XPE Foam or IXPE Foam material. 5. Pass the thin XPE IXPE foam material through the secondary processing unit of the XPE IXPE Foam machine line for the thickening process. Usually, a layer of 4~5mm black XPE IXPE foam material is sandwiched between 2 layers of 3mm black XPE IXPE foam material, so as to obtain a composite material with a thickness of 10~11mm. Through the above 5 steps, the sound insulation material for floating floor is completed.

In the production process of XPE foam and IXPE foam materials, according to different application requirements, various preparations can be added to give the product various unique properties, such as: flame retardant, weather resistance, aging resistance, chemical resistance, mildew resistance Wait. According to different additives, XPE foam and IXPE foam products can be divided into antibacterial enhanced type, flame retardant type, conductive type, weather-resistant type, anti-ultraviolet type, etc. Antibacterial enhanced IXPE is suitable for high-end series products of green home life; flame-retardant XPE foam and IXPE foam are suitable for automobiles, construction and home decoration, etc.; conductive IXPE foam is suitable for electronic appliances, precision packaging and other applications; weather-resistant and anti-ultraviolet XPE foam And IXPE foam is suitable for outdoor, water and other places. In addition, XPE foam and IXPE foam with other special properties can also be produced according to customer needs.

Air-conditioning cooling liquid copper pipes need to be insulated. The main materials of air-conditioning insulation pipes usually used are EPDM, NBR, EPE, XPE, IXPE and other rubber and plastic foam materials. EPDM and NBR are foam rubbers with open-cell structure, high water absorption rate, and easy to age outdoors, but the material cost is low and it is widely used. EPE is a foamed plastic tube that can be directly molded, but due to its open-cell structure, it also has the disadvantages of high water absorption and easy aging. Because it can be directly formed into a tube, the production cost is low, and the installation is convenient, so it is used more in areas with less developed economy. XPE and IXPE are closed-cell foamed plastics, which are much higher than other materials in terms of thermal insulation and comprehensive performance. XPE foam and IXPE foam are cross-linked foam materials with high cross-linking degree, excellent weather resistance and corrosion resistance. Long service life outdoors. However, when a single XPE or IXPE foam material is used to make pipes, it is more difficult to manufacture because of the greater internal stress of the plastic. Because of the high cost, it is usually used in high-demand occasions.

IXPE foam material is a material with high technical requirements. It has high requirements on product formula, production process, machine equipment configuration and so on. Manufacturers need to customize different product formulas and production processes according to the needs of downstream users. Qin Ding has a large number of customers in this industry and has accumulated rich experience. It can provide different equipment according to the different markets targeted by customers, and can provide customers with a full range of materials, technical formulas, production processes, and secondary processing. And we can provide directional services.

IXPE foam material has the following excellent physical properties: Flame retardant: The IXPE foaming products can reach FMVSS302 standard, UL standard, HB, V-2, V-1, V-0 (HB UL94 plastic flame retardant grade inspection method). Environmental protection: tested by SGS, the world's most authoritative organization, 100% of the IXPE foaming products have passed the EU ROSH environmental protection directive, free of peculiar smell and toxic substances. Heat insulation: IXPE foam products independent cell structure, no air circulation, thermal conductivity ≤0.04W/m∙k. Sound insulation: 100% airtight chamber, effectively reducing the sound intensity, excellent sound insulation, meeting STC-73, IIC-72 standards Waterproof: water absorption rate is lower than 0.02g/cm2 Aging resistance: After being modified by electron irradiation, IXPE foaming products have good weather resistance and chemical resistance, and the aging time is more than 15 years.

The molding methods of polyethylene foam include extrusion, injection, molding, orientation and other methods. Among them, the extrusion method is divided into direct extrusion foaming and cross-linking foaming after extrusion. After extrusion, cross-linked foaming can be divided into chemical cross-linked foaming, physical cross-linked foaming and mixed cross-linked foaming.
