摘要： A process for selectively forming an antislip surface on a product thermoformed from a plastic sheet is applied to truck bed liners, for example. The surface of a plastic sheet of HDPE or other thermoplastic material is cleaned and masked, preparing a good molecular bonding surface on the selected surface areas. A sprayable or liquid polymer designed to achieve desired characteristics of hardness and toughness without brittleness, such as a thermosetting elastomeric polymer, is formed into droplets, which are sprayed or otherwise applied onto the exposed surface area. The droplets form a stippled pattern of primarily separate bumps, occupying substantially less than 50% of the exposed area. After partial hardening of the bumps, the plastic sheet is thermoformed to produce the thermoformed product. Thermoforming tightly bonds the droplets to the sheet, hardens the droplets forming macroscopic asperities, increases or enhances the three dimensional surface relief, and explodes some droplets with entrapped air to increase surface roughness.

摘要： Thermoplastic products such as vehicle cargo area liners, floor mats, recreational and playground equipment, cargo pallets, and wet area walking surfaces are provided with an antislip surface treatment. The antislip surface is made up of individual non-interconnected asperities of an antislip polymer material, which do not form a continuous film over the surface of the thermoplastic product. The thermoplastic product is especially made of high density polyethylene. The antislip polymer is preferably a thermoset polymer, and most particularly is a polyurea/isocyanate polymer. The antislip polymer is preferably applied by spraying, and then the product is heat treated at a temperature in the range from 100 to 200° F., or is thermoformed at a temperature in the range from 250 to 550° F. The antislip asperities are durably bonded onto the thermoplastic base material, and provide a significantly increased coefficient of friction. The asperity size, height, and hardness can be controlled by adjusting the processing conditions. The asperities may have an increased surface relief due to a so-called “moth effect” and an increased surface roughness due to cratering as a result of a so-called “volcano effect” in the process using thermoforming.

A sprayable or liquid polymer selected to achieve desired characteristics of hardness and toughness without brittleness, such as a thermosetting elastomeric polymer, is formed into droplets, which are sprayed or otherwise applied onto the selected surface area. The droplets form a stippled pattern of primarily separate bumps across the selected surface area to be treated, occupying substantially less than 50% of the exposed area. After partial hardening of the bumps, the plastic sheet is thermoformed at thermoforming temperatures to produce the thermoformed product. Thermoforming tightly bonds the bumps or droplets to the thermoplastic sheet material, hardens the droplets forming macroscopic asperities, increases or enhances the three dimensional surface relief, and explodes some droplets with entrapped air to increase surface roughness.
