Abstract
The utility model discloses a PVC floor felt, which adopts a sheet structure. The PVC floor felt is composed of a fiber glass mat and PVC emulsion solidified layers coated on two sides of the fiber glass mat; and the diameter of the fiber used in the fiber glass mat ranges from 10 Mum to 15 Mum, and the thickness thereof is controlled between 37 Mum and 40 Mum. The utility model has the advantages of environmental protection, sanitation, smooth and uniform surface, high intensity, strong wearing resistance, low swelling coefficient and the like. When in use, the PVC floor felt basically prevents the phenomena of arch camber and puckering and the like, is simple to repair, and greatly prolongs the service life.
Description
Technical field
The utility model relates to a kind of novel floor decorative material, is specially a kind of PVC floor felt.
Background technology
The PVC floor has light weight as a kind of new decorative material, and picture on surface is bright-coloured, and the surface is not easy to wear, adopts overlap joint to paste technology, and advantages such as easy construction enjoy external welcome.But it makes intensity lower owing to having added more packing material, and fragility is bigger.Because PVC properties of materials own causes the shortcoming of expanding with heat and contract with cold easily, arch camber, splicing slit in the use of family and public place, can occur and become big phenomenon and be difficult to repair influence and use.At present, the research of floor producer adds glass chopped yarn in PVC floor batch mixing is produced, but effect is not clearly.And general mat producer will be coated with solvent borne PVC oil on felt, but has increased the man-hour of producer on the one hand, on the other hand because the volatilization of solvent directly influences the healthy of workman, contaminated environment.
Summary of the invention
For overcoming above-mentioned shortcoming, the utility model provides a kind of intensity height, and abrasion resistance is strong, and the PVC floor felt of environmentally-friendly sanitary, has surfacing, evenly simultaneously, the long-term characteristics such as do not have protuberance, non-wrinkle of using.
Concrete scheme of the present utility model is: a kind of PVC floor felt, structure is made up of glass fibre mat and the PVC emulsion cured layer that is coated on the glass fibre mat both sides in the form of sheets.
As further improvement of the utility model: in order to increase the intensity of floor felt, reduce the coefficient of expansion, the diameter of the used fiber of described glass fibre mat is at 10um-15um; And its THICKNESS CONTROL is at 37-40um.
PVC emulsion in the utility model by the pressurization of heating, is added modified additive and is made the reaction of PVC particle emulsion polymerization form water-based PVC emulsion when emulsion is synthetic.And then the thickener that adds identical polar in water-based PVC emulsion is made the pasty state emulsion with certain viscosity.Adopt roller coating technology that PVC pasty state emulsion is coated on the mat uniformly simultaneously, through making PVC floor felt after the oven dry.Wherein, in the emulsion cured layer on felt surface, PVC floor PVC content depend primarily on roller coat speed, be coated with the finish of roller, the quality of product in final decision, it is also just most important therefore to control its starching amount well.Therefore in the process of roller coat, the conveying of mat becomes the speed of 0-0.6% poor with the speed designs of roller coat in the utility model, can make mat coating two sides can both evenly adsorb the PVC emulsion like this.After above-mentioned selection and technology, the PVC floor felt that the utility model is produced, has environmentally-friendly sanitary, surfacing, even, advantages such as intensity height, abrasion resistance is strong, the coefficient of expansion is low, make that this PVC floor felt uses the back not to have arch camber substantially, phenomenon such as non-wrinkle occurs, and reparation simply, can prolong its application life greatly.
Description of drawings
Fig. 1 is a section structure schematic diagram of the present utility model.
Among the figure, 1 is glass fibre mat; 2 is PVC emulsion cured layer.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described
As shown in Figure 1: this PVC floor felt is made up of glass fibre mat 1 and the PVC emulsion cured layer 2 that is coated on the glass fibre mat both sides, in the form of sheets structure; Wherein, glass fibre mat thickness is 40um; And the diameter of its used fiber is 12um.
Preparation technology of the present utility model is as follows:
Preparation PVC emulsion:, when emulsion is synthetic, add auxiliary agent and make the reaction of PVC particle emulsion polymerization form water-based PVC emulsion by the pressurization of heating; And then the thickener that adds identical polar in water-based PVC emulsion is made the pasty state emulsion of viscosity greater than 1.50mpaS; Adopt roller coating technology that PVC pasty state emulsion is coated on the mat uniformly, through making PVC floor felt after the oven dry.Wherein, the transporting velocity of mat is 25 meters/minute, and the speed of roller coat is 25.2 meters/minute.
The utility model is after the direct hot pressing of client is used, and the intensity on PVC floor will increase by 10% after testing, and the coefficient of expansion is by original 0.6*10
-41/ ℃ reduces to 0.3*10
-4Below 1/ ℃.
The utility model technology is simple, but and rolling production, can be mass-produced.
Claims (3)
