Solution Overview

Problem

Existing plastic floor tiles contain environmentally unfriendly phenolics in stabilizers, which can harm humans and the environment, and the use of calcium zinc stabilizers or water talc stabilizers reduces plasticization rates, affecting productivity and printability.

Innovation Solution

A plastic floor tile structure with a resin composition comprising 100 phr of polyvinyl chloride resin, 5 phr to 20 phr of plasticizer, 4 phr to 15 phr of composite heat stabilizer, 0.5 phr to 3 phr of accelerant, 1 phr to 5 phr of toughener, 0.1 phr to 0.5 phr of composite lubricant, and 0.1 phr to 1 phr of antioxidant, using a calcium-zinc stabilizer and an auxiliary stabilizer, and an accelerant copolymerized from a vinyl chloride monomer and a polyester monomer.

1Object-affected harmful factors

If calcium zinc stabilizer or water talc stabilizer is used, then environmental safety is improved, but plasticization rate decreases

Engineering Contradiction:

Improveenvironmental safetyVSAvoidplasticization rate

Core Design Contradiction:

Object-affected harmful factorsVSProductivity

Solution Approach 1:

The patent uses a composite heat stabilizer system combining calcium zinc stabilizer (3-10 phr) with auxiliary stabilizer (1-5 phr) to achieve both environmental safety and adequate plasticization rate. The composite approach allows the calcium zinc stabilizer to provide environmental benefits while the auxiliary stabilizer compensates for reduced plasticization, resolving the contradiction between environmental safety and productivity

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

The patent optimizes the dosage parameters of the calcium zinc stabilizer (3-10 phr) and auxiliary stabilizer (1-5 phr) to balance environmental safety and plasticization rate. By precisely controlling these parameter ranges, the invention achieves environmental protection without excessively compromising productivity

Inventive Principle:

2Object-affected harmful factors

If calcium zinc stabilizer or water talc stabilizer is used, then environmental safety is improved, but printability decreases

Engineering Contradiction:

Improveenvironmental safetyVSAvoidprintability

Core Design Contradiction:

Object-affected harmful factorsVSManufacturing precision

Solution Approach 1:

The composite heat stabilizer system (calcium zinc stabilizer + auxiliary stabilizer) resolves the contradiction between environmental safety and printability. The auxiliary stabilizer component compensates for the negative impact on printability caused by calcium zinc stabilizer, ensuring both environmental protection and manufacturing quality are achieved

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

The auxiliary stabilizer acts as an intermediary substance that mediates between the environmental benefits of calcium zinc stabilizer and the manufacturing quality requirements. It bridges the gap by compensating for the reduced printability, allowing the system to achieve both environmental safety and acceptable printability

Inventive Principle:

Principle #24Intermediary (Mediator)

3Temperature

If tin stabilizer or zinc stabilizer containing phenolics is used, then heat resistance is improved, but environmental safety deteriorates

Engineering Contradiction:

Core Design Contradiction:

TemperatureVSObject-affected harmful factors

Solution Approach 1:

The patent extracts and removes the harmful phenolic components (such as bisphenol A, renohol, or phenol) from the stabilizer system while retaining the essential heat stabilization function through calcium zinc stabilizer and auxiliary stabilizer, thus achieving environmental safety without sacrificing heat resistance

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces expensive and harmful phenolic-based stabilizers with environmentally friendly calcium zinc stabilizer combined with auxiliary stabilizer. This substitution uses safer, more environmentally compatible materials to achieve the same heat resistance function without the toxic side effects

Inventive Principle:
