Abstract

The invention belongs to the technical field of organic and inorganic composite materials and discloses a bag type environment-friendly auxiliary special for PVC floor substrate production and a preparation method thereof. The bag type environment-friendly auxiliary special for PVC floor substrate production is composed of, by weigh part, 2.5-4.5 parts of coupling agent, 24-45 parts of calcium-zinc stabilizer, 15-25 parts of processing auxiliaries, 15-25 parts of flexibilizer, 4-8 parts of internal lubricant, 4-8 parts of external lubricant and 0-6.5 parts of toner. The preparation method of the bag type environment-friendly auxiliary special for PVC floor substrate production comprises the steps of (1) premixing the calcium-zinc stabilizer and the coupling agent at a weight ratio of 10:1at 100 DEG C; (2) mixing and drying the mixture above, the processing auxiliaries, the internal lubricant, the external lubricant and the toner according to the preset proportional ratio at 80 DEG C;(3) screening the mixture obtained in the step (2); (4) weighing, measuring and packaging the screened materials. The bag type environment-friendly auxiliary special for PVC floor substrate productionimproves the dispersibility of various auxiliaries and enhances compatibility of calcium powder and PVC resin powder, and by screening and controlling raw materials, avoids the physical and mechanical performance deficiency caused by raw material difference.

Description

technical field [0001] The invention belongs to the technical field of organic-inorganic composite materials, and in particular relates to a bag-type environmental protection additive specially used in the production of PVC stone-plastic floor substrates. Background technique [0002] With the improvement of public environmental protection and health awareness, plastic products such as PVC replace traditional wood as building decoration materials and gradually attract people's attention. As we all know, compared with wood flooring or laminate flooring, PVC stone-plastic flooring has many advantages such as flame retardancy, zero formaldehyde, non-absorbent, convenient installation and maintenance, and low cost, so it has become a new favorite in the domestic and foreign flooring markets. [0003] The composition of PVC stone-plastic floor is characterized by calcium powder filling of more than 300phr. Compared with other types of PVC extruded products, high calcium powder fi...
