Problems solved by technology

But the problem is that the rapid development of the construction industry has brought a large amount of construction waste. These construction wastes are piled up in the open air or landfilled without any treatment, and consume a lot of construction funds such as land acquisition fees and garbage removal fees, which have a negative impact on the environment and even Great impact on national ecology

Embodiment 1

[0044] (1) Put the mixed powder of discarded fir, maple and oak into a pulverizer at a ratio of 2:5:2, and grind it into a powdery substance. Grind it into powder, and get PVC powder according to the ratio of 2:3.

[0045] (2) Pour the pulverized charcoal powder on the sieve plate, and use the sieve plate to filter out the charcoal powder with a particle size ranging from 100 to 135 mesh. (3) Place the charcoal powder with the required size in a heating oven at 178° C., and dry it for 3 hours to obtain dry charcoal powder.

[0046] (4) Take 1000g of dry charcoal powder and put it into a high-speed mixer, set the speed of the mixer to 15-25 r / min, add about 1000g of PVC powder, mix evenly for 45min, then add about 60g of OSBH foaming agent, 60g of Silane coupling agent KH-560 stabilizer, 60g of XT-1 type rare earth stabilizer and 60g of brominated polystyrene.

[0047] (5) Pour the raw material and additive mixture in step (4) into the three-screw extruder, and set the barrel...

Embodiment 2

[0054] Compared with Example 1, change the PVC powder into 1500g in the step (4), and other conditions remain unchanged.

Embodiment 3

[0056] Compared with embodiment 1, change PVC powder into 2000g in the step (4), other conditions remain unchanged.

Abstract

The invention relates to a waste wood reinforced recycled PVC foam floor and a preparation method thereof. The mixed material of waste fir, maple and oak is ground into powder, industrial waste PVC plastic and new semi-rigid PVC plastic are ground into powder, and mixed. After uniformity, add foaming agent, stabilizer, coupling agent, lubricant, stir at high temperature, extrude uniform pellets through a three-screw extruder, heat and melt, and shape the molten material through a mold to form waste wood reinforced recycled PVC Foam floors. Compared with the prior art, the present invention is cheap, can be popularized in a large area in the household industry, and saves production costs. The "hollow" structure can play the role of shock absorption and sound insulation; the product has high impact resistance and compression strength, Improve stability, prolong the service life and years of the floor, the floor surface is not easy to deform, can realize large-scale mechanized production, and reduce labor costs.

Description

technical field [0001] The invention relates to the field of construction waste recycling, in particular to a waste wood reinforced recycled PVC foam floor and a preparation method thereof. Background technique [0002] The rapid development of China's economy has led to the rapid rise of China's real estate industry. The related construction industry and decoration industry are also full of vigor and vitality. But the problem is that the rapid development of the construction industry has brought a large amount of construction waste. These construction wastes are piled up in the open air or landfilled without any treatment, and consume a lot of construction funds such as land acquisition fees and garbage removal fees, which have a negative impact on the environment and even The national ecology has a huge impact. Construction waste generally refers to waste wood, dregs, waste materials, silt and other wastes generated during the construction, laying or demolition, and repa...
