Embodiment

[0124] combination

[0125]The composition is a two-component polyurethane flooring composition. The compositions of component (A) and component (B) are shown in Table 1-Table 3 below. The following ingredients were mixed to form Component (A) and Component (B):

[0126]

[0127] Table 1 Component (A)

[0128]

[0129]

[0130] Table 2 component (B)

[0131]

[0132] table 3

[0133] For the compositions shown in Table 4, the amounts of glass beads 1, glass beads 2 and fly ash shown in Table 4 were added to component (A), replacing the fine powdered dolomite with the added amount. The amounts of glass beads 1, glass beads 2, and fly ash shown in Table 4 refer to wt% based on the total composition (the sum of (A) and (B) components).

Abstract

The present invention relates to polyurethane compositions comprising a polyol component (A) comprising at least one polyol, a hardener component (B) comprising at least one polyisocyanate and glass microspheres, as well as other optional additives and fillers. In addition, the invention also relates to a method for manufacturing a floor by applying the polyurethane composition of the invention. The polyurethane composition of the present invention is suitable as a flooring material.

Description

technical field [0001] The present invention relates to polyurethane compositions for the manufacture of flooring, especially for marine applications. [0002] Background of the invention [0003] Flooring compositions for outdoor applications can be stressed by extremely harsh environmental conditions, especially sunlight. Sunlight is an electromagnetic wave, which is divided into 3-7% ultraviolet rays, 47-50% visible light and 43-50% infrared rays. The effects of sunlight vary by season and region, but infrared rays cause the most damage to floor coating compositions. The absorption of infrared rays causes the molecules to vibrate, which generates heat and energy within the floor substrate. The heat generated within the floor substrate is highly undesirable as it can lead to failure of the floor coating composition, causing considerable wear and tear. In addition, it can cause chipping, scoring, skewing, scratching, corrosion or discoloration of the surface of the floor ...
