Abstract
The invention relates to wet-method roof producing process by glass fibers spread with adhesive, which comprises steps: firstly, spreading polyurethane adhesive on one surface of a glass fiber felt by an adhesive spreader so as to produce a glass fiber felt with adhesive, secondly, sequentially laying non-woven cloth, the glass fiber felt with adhesive, hard polyurethane, another glass fiber feltwith adhesion and another non-woven felt from top to bottom, realizing pressing forming and producing a semi-finished product, thirdly, cooling and shaping the semi-finished product produced after pressing forming at normal temperature to produce a formed semi-finished product, fourthly, sequentially laying a fabric, an adhesive film and the formed semi-finished product from top to bottom prior to laminating the fabric, fifthly, cooling and shaping the formed semi-finished product, which is produced by means of laminating the fabric, at constant temperature, and sixthly, cutting the formed semi-finished product which is shaped by means of cooling by a water jet. Accordingly, a roof is produced. By the aid of the wet-method roof producing process, the weight of the roof is greatly lightened, and adhesive spreading quantity can be precisely controlled by means of spreading the adhesive on the single surfaces of the glass fibers.
