Title
(EN) METHOD OF FORMING ANTISLIP SURFACES ON THERMOFORMED PRODUCTS
(FR) PROCEDE DE REALISATION DE SURFACES ANTIDERAPANTES SUR DES PRODUITS FAÇONNES A CHAUD
Abstract
(EN)
A thermoformed plastic product, such as a truck bed liner (60), having an antislip surface is formed. A clean surface of a sheet of, for example HDPE, is masked. Droplets of a sprayable or liquid polymer, such as a thermosetting elastomeric polymer are sprayed or otherwise applied onto the exposed masked off surface area. The droplets form a stippled pattern of primarily separate bumps which upon hardening are hard, but not brittle. After partial hardening of the bumps, the plastic sheet is thermoformed. Thermoforming tightly bonds the droplets to the sheet and further hardens the droplets into asperities (64, 65). Some asperities (65) containing entrapped air explode during thermoforming resulting in rough edges (66).
(FR)
L'invention consiste à réaliser un produit en plastique façonné à chaud, tel qu'un revêtement de plateau de camion (60), possédant une surface antidérapante. On masque une surface propre d'une feuille de HDPE par exemple. On applique, généralement par pulvérisation, des gouttelettes d'un polymère pulvérisable ou liquide, tel qu'un polymère élastomère thermodurcissant, sur la zone de surface exposée. Les gouttelettes constituent une configuration grenée de protubérances séparées, qui durcissent mais ne deviennent pas cassantes. Après le durcissement partiel des protubérances, on façonne à chaud la feuille en plastique. Le façonnage à chaud fixe fortement les gouttelettes à la feuille et les durcit encore, de manière à former des aspérités (64, 65). Quelques aspérités (65) contenant de l'air piégé explosent pendant le façonnage à chaud, ce qui produit des bords rugueux (66).
