The disclosure provides a low-density PVC plastics flooring and a preparation method thereof, which belongs to the technical field of films for floor. The disclosure provides a low-density PVC plastics flooring, which is prepared from components including, in parts by mass, 100 parts of PVC, 300-380 parts of calcium carbonate, 7-12 parts of a stabilizer, 2-8 parts of processing aid ACR, 12-16 parts of a foaming regulator, 0.1-0.5 parts of a foaming agent, 2-4 parts of G60 lubricant, and 2-4 parts of PE wax. In the disclosure, the density of the PVC plastics flooring is reduced to 1.4-1.6 g/cm.sup.3 even increasing the amount of calcium carbon, thereby greatly reducing the production cost and improving the economic efficiency.

A floor, wall, or ceiling panel has a base made of a wood material and an upper veneer. The base and the veneer are hot-pressed together while incorporating a resin layer. During the pressing process, pores, cracks, and/or gaps in the veneer are filled with resin. In particular, the pressing process is carried out such that the veneer is saturated with resin, and the resin can be seen on the surface of the veneer after the pressing process The adhesion of the veneer to the base and the smoothing of the veneer are thus carried out in one operation.

The invention relates to the recycling of used rubber products, more specifically to the recycling of Ground Tire Rubber (GTR) from cars and trucks. Provided is a method for reclaiming rubber, comprising the steps of (i) providing a starting material comprising a vulcanized rubber polymer; (ii) subjecting the starting material to mechanical stress and at a temperature of at least 200? C. to achieve at least a partial destruction of the cross-links and the backbone structure of the rubber polymer into fragments; and (iii) reconstituting at least part of the fragments in the presence of a branching/grafting agent to obtain a renewed rubber composition.

The present invention is directed to low solid surface coating compositions and methods of using the same. The low solid surface coating compositions comprise a self-crosslinking polymer, a solvent, a surfactant, and water. The low solid surface coating compositions can preferably have a total solid content of less than 15%.

A mineral-based floor panel including a mineral-based core, wherein the panel includes at least one groove. The at least one groove may be provided in a rear side of the panel. There is also disclosed other such mineral-based panels, such as a building panel, a wall panel, a ceiling panel or a furniture panel. There is also disclosed a method for forming such grooves in a mineral-based panel. Furthermore, there is disclosed a mineral-based panel including a mineral-based core and polymer-based lower layer(s) attached to the core. A locking system of the panel includes a strip extending horizontally beyond an upper portion of the panel, wherein at least a horizontal portion of the strip is entirely formed in the polymer-based lower layer(s).

Provided is a hard floor panel having a top side and a bottom side and having side edges along the panel sides for floating installation to form a floor panel composite. At least two floor panels are joined together in each case, the opposite side edges being provided with tongue-and-groove profiles, a tongue and a joining surface is provided in a first side edge and a groove and a joining surface is provided in a second opposite side edge. The tongue of the first side edge has an upper side and a lower side. A projection with a contact surface is provided on the lower side of the tongue. The joining surface of the first side edge extends from the upper side of the floor panel towards the upper tongue side and the joining surface is beveled.

An anti-explosion flooring material is disclosed. The material is prepared by foaming modification and rust prevention treatment of an iron alloy material and other auxiliary materials having components in percentage by weight: 85% of iron, 8% of manganese, 6% of silicon, and the remainder carbon. Because a foaming agent and rare earth are added, the static conducting performance of the flooring material is improved.

The sub-floor brace for abating squeaking floors is a structural element that is configured for use with a supported flooring. The sub-floor brace for abating squeaking floors supports the supported flooring from the ceiling side of the supported flooring. The sub-floor brace for abating squeaking floors supplements the load carrying capacity of the joists that are supporting the supported flooring by creating a load path from the supported flooring to a supporting flooring located in an inferior location to the supported flooring. The supplemental load paths created by the sub-floor brace for abating squeaking floors reduce the squeaking noise commonly associated with aging floors. The sub-floor brace for abating squeaking floors is a telescopic structure that comprises a first support, a second support, and a fastener. The fastener attaches the first support to the second support.
