Abstract

La présente invention concerne une baignoire pourvue d'un coussin de gel souple, et son procédé de fabrication. Le risque de glisser dans la baignoire est réduit du fait que celle-ci est souple et comporte un coussin de gel. Ce système permet à l'eau dans la baignoire de rester chaude, génère un bruit minimal et maintient un haut niveau de propreté. De plus, la baignoire est étanche par l'auto-rétablissement de charges intermédiaires de façon à empêcher l'eau de fuir même lorsque la surface de la baignoire est cassée ou endommagée. En outre, la baignoire comporte une triple structure étanche constituée d'une couche de revêtement, d'une couche de coussin de gel et d'un matériau de renforcement, ce qui favorise la sécurité, l'isolation thermique, la durabilité, le confort, la propreté, une bonne utilisation et confère une simplicité. Cette invention comprend une première étape (S1) pour préparer un moule (2) en forme de baignoire; une deuxième étape (S2) pour former une couche superficielle (3) sur la surface du moule (2); une troisième étape (S3) pour mouler un moule avant (100) par formation d'une couche en tension (4) sur la surface de la couche superficielle (3); une quatrième étape (S4) pour préparer une enveloppe de renforcement arrière (200) qui recouvre l'extérieur du moule avant (100); une cinquième étape (S5) pour placer l'enveloppe de renforcement arrière (200) sur l'extérieur du moule avant (100) et raccorder l'enveloppe de renforcement arrière (200) et le moule avant (100); une sixième étape (S6) pour former une couche de gel (9) en remplissant l'intervalle entre le moule (100) avant et l'enveloppe de renforcement arrière (200) et une septième étape (S7) pour un durcissement naturel primaire, le dégagement du moule (2), un durcissement thermique secondaire et la finition.
