Glueless Plastic Flooring Backing via Melt-Spray Adhesion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional plastic flooring manufacturing involves the use of glue to adhere the backing, leading to environmental pollution and complex fabrication processes.
Innovation Solution
A method of making plastic flooring with a backing that eliminates the use of glue by using an electric control system to spray and solidify polyvinyl chloride (PVC) or polyurethane (PU) backing material onto the substrate, utilizing a five-roller pressing machine and a drop plastic machine to adhere the backing in various shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If glue is used to adhere the backing on the substrate, then the backing can be firmly attached, but environmental pollution increases and the fabrication process becomes more complex
Solution Approach 1:
The invention extracts and eliminates the harmful glue component from the flooring system by replacing it with a glueless backing structure that achieves adhesion through mechanical interlocking and material properties rather than chemical adhesives
Solution Approach 2:
The invention changes the adhesion mechanism from chemical bonding (glue) to physical bonding through modified backing material properties, surface characteristics, and installation parameters that enable firm attachment without harmful substances
2Strength
If glue is used to adhere the backing, then the backing can be firmly attached, but the fabrication process becomes more complex and troublesome
Solution Approach 1:
The invention removes the glue application step and associated equipment from the fabrication process, simplifying the overall system while maintaining backing adhesion through alternative mechanical and material-based mechanisms
Solution Approach 2:
The backing material is designed to achieve self-adhesion or self-locking characteristics that eliminate the need for external glue application, allowing the backing to attach itself to the substrate through its own structural properties
3Ease of manufacture
If traditional backing adhesion methods are used, then the process is simple, but environmental pollution occurs and the process becomes troublesome
Solution Approach 1:
The invention converts the potential harm of complex fabrication into benefit by designing a system where the slight increase in manufacturing sophistication eliminates harmful glue usage, resulting in net environmental and operational benefits

AI summary
Equipment for making plastic flooring having backing (14) contains: a pressing machine (50) configured to press a substrate (11), a printing layer (12), and an anti-abrasion layer (13) together, thus producing a semi-finished plastic flooring (10'); a drop plastic machine (60) configured to glue dispense or to spray onto a back surface of the semi-finished plastic flooring (10'). The drop plastic machine (60) includes a base (61) on which a delivery mechanism (62) is secured, wherein the delivery mechanism (62) delivers the semi-finished plastic flooring (10') to at least one molding mechanism (63). The backing material is melt and is glue dispensed or is spray onto a back surface of the semi-finished plastic flooring (10') by using the drop plastic machine (60), and the backing material is adhered on the back surface of the semi-finished plastic flooring (10') after being solidified, thus obtaining the plastic flooring having the backing (14).
