Problems solved by technology

[0002] Existing composite flooring generally has disadvantages such as low product toughness, poor thermal stability, high shrinkage rate and expansion rate. In the actual production and use process, these determinations lead to relatively poor quality of the product, and the quality cannot be guaranteed, thus making the product relatively cost-effective. lower

Embodiment 1

[0013] The composite floor middle layer material with excellent thermal stability described in this embodiment is composed of PVC, plasticizer, stabilizer, calcium carbonate and coupling agent, wherein the mass parts of each component are: 100 parts of PVC, plasticizer 36 parts, 2 parts of stabilizer, 441.6 parts of calcium carbonate, 2.2 parts of coupling agent.

[0014] The stabilizer is a calcium-zinc stabilizer.

[0015] The order number of described calcium carbonate is 325 orders.

[0016] The coupling agent is a titanate coupling agent.

[0017] A kind of preparation method of composite floor material with excellent thermal stability, the first step, dilute the coupling agent: first dilute the coupling agent, use 95% pure ethanol as diluent, according to ethanol and coupling agent 3: Mixing at a ratio of 1; the second step, blending with inorganic fillers: premix the diluted mixed liquid of coupling agent and ethanol with calcium carbonate, add 0.5% of the total amoun...

Embodiment 2

[0020] A kind of preparation method of composite floor material with excellent thermal stability, the first step, dilute the coupling agent: first dilute the coupling agent, use 95% pure ethanol as diluent, according to ethanol and coupling agent 3: Mixing at a ratio of 1; the second step, blending with inorganic fillers: premix the diluted mixed liquid of coupling agent and ethanol with calcium carbonate, add 0.5% of the total amount of calcium carbonate, so that the coupling agent can be evenly distributed On the surface of the calcium carbonate, add the rest of the calcium carbonate, then stir with a mixer for 8 minutes to discharge the material, cool to normal temperature for use; the third step, add the calcium carbonate mixed in the second step to PVC, plasticizer, stabilizer In the mixed powder of the three agents, the blender is blended for 8 minutes to make the coupling agent and the polymer produce a coupling effect; the fourth step is to open the mill: after all the ...

Embodiment 3

[0022] A kind of preparation method of composite floor material with excellent thermal stability, the first step, dilute the coupling agent: first dilute the coupling agent, use 95% pure ethanol as diluent, according to ethanol and coupling agent 3: Mixing at a ratio of 1; the second step, blending with inorganic fillers: premix the diluted mixed liquid of coupling agent and ethanol with calcium carbonate, add 0.5% of the total amount of calcium carbonate, so that the coupling agent can be evenly distributed On the surface of calcium carbonate, add the rest of calcium carbonate, then use a mixer to stir for 5 minutes to discharge, cool to room temperature for use; the third step, add the calcium carbonate mixed in the second step to PVC, plasticizer, stabilizer In the mixed powder of the three agents, the blender is blended for 7 minutes to make the coupling agent and the polymer produce a coupling effect; the fourth step is to open the mill: after all the materials are blended...

Abstract

The invention relates to the field of laminate flooring, especially to a laminate flooring middle-layer material with excellent thermostability. The laminate flooring middle-layer material is composed of PVC, a plasticizer, a stabilizing agent, calcium carbonate and a coupling agent. A preparation method of the laminate flooring middle-layer material with excellent thermostability comprises the following steps: Step 1, the coupling agent is diluted; Step 2, the diluted coupling agent is mixed with inorganic filler; Step 3, calcium carbonate obtained by mixing in the Step 2 is added into a mixed powder of the PVC, the plasticizer and the stabilizing agent; and Step 4, milling. The laminate flooring middle-layer material prepared by the above method has excellent thermostability, its expansion rate reaches 0.065% and its shrinkage reaches 0.03%. Meanwhile, a titanate coupling agent adopted has a good effect of coupling with a thermal polymer and calcium carbonate, and calcium carbonate and the PVC are combined through chemical action. Thus, thermostability of the size is guaranteed.
