Embodiment 1

[0044] This embodiment provides a kind of multi-layer composite high wear-resistant and acid and alkali resistant PVC floor glue, such as figure 1 As shown, it includes an epoxy resin surface wear-resistant layer 7, a glass fiber reinforced PVC middle layer 5, a PVC elastic layer 4 and a glass fiber reinforced PVC base layer 3 sequentially compounded from top to bottom;

[0045] For the entire preparation process, see figure 2 As shown, the details are as follows:

[0046] (1) Add the measured construction waste PVC recycled materials, stabilizers, plasticizers, glass fibers, etc. into a high-speed mixer with a temperature of 150°C and a stirring speed of 700r / min in the order of solid first and then liquid, and stir for 15 minutes , so that the PVC and additives are mixed evenly, and the liquid additives are completely absorbed by the solid. In this embodiment, the material ratio of each layer is as follows:

[0047] Glass fiber reinforced PVC base layer 3: 100 parts of PVC ...

Embodiment 2

[0060] Compared with Example 1, in the step (1), the mixing time of PVC recycled material, stabilizer, plasticizer, glass fiber, etc. in the high-speed mixer is changed to 20min, and other conditions remain unchanged.

Embodiment 3

[0062] Compared with Example 1, the auxiliaries such as PVC recycled material, foaming agent, stabilizer, plasticizer in the step (1) are changed into 900r / min in the high-speed mixer, and other conditions remain unchanged.

Abstract

The invention relates to a multi-layer composite PVC (polyvinyl chloride) floor adhesive with high wear resistance and acid and alkali resistance as well as preparation and application thereof, a building waste polyvinyl chloride recycled material is utilized, a series of additives are added, and processes such as calendaring, extrusion and co-pressing are performed to obtain the specific multi-layer composite PVC floor adhesive with high wear resistance and acid and alkali resistance, so that a traditional plastic floor is updated and upgraded. The product has a multi-layer structure comprising the epoxy resin surface wear-resistant layer, the glass fiber reinforced PVC middle layer, the PVC elastic layer and the glass fiber reinforced PVC base layer, and the layers cooperate with one another, so that the PVC floor adhesive is endowed with excellent properties of acid and alkali resistance, wear resistance, scratch resistance, water resistance, moisture resistance, easiness in cleaning and good dimensional stability; the composite material can meet the requirements of most industrial terraces.

Description

technical field [0001] The invention belongs to the technical field of building materials, and relates to a multi-layer composite high wear-resistant and acid-base resistant PVC floor glue and its preparation and application. Background technique [0002] In today's society, the process of urbanization and industrialization in my country has been significantly accelerated, which inevitably produces a large amount of construction waste, especially polymer materials that are difficult to biodegrade such as PVC. How to recycle them reasonably has long been a research topic. hotspots. [0003] Since the early 1980s, plastic flooring has been widely used in offices, hotels, schools, factories, kindergartens and other public places along with the rapid development of my country's polymer industry, becoming a popular flooring product. However, with the continuous emergence of a large number of modern industrial production areas across the country, the update and iteration speed of ...
