摘要： This invention relates to a process for producing phenolformaldehyde foams, also known as phenolic foams, of improved properties. The inventive feature resides in using a controlled combination of the various components in the curing reaction mixture and in controlling the temperature within the mass of the curing mixture. The process is applicable to production of block or laminated foams. Phenolic foams find increasing use in building applications where their thermal insulation and fire resistant properties are of value.

摘要： The present invention relates to a process and an apparatus for producing phenolic foam laminates with improved surface appearance. The process involves applying pressure on the foam forming mixture through one of its facings by a flexible member. The member is sufficiently flexible to allow continual rise of the foam but also smoothes out any uneven rise under the applied pressure thereby producing a laminate which has a surface immediately below the facing substantially free of any voids, craters or wrinkles.

摘要： A continuous process for the production of a phenolic foam composite comprises bringing a preformed layer of flexible insulating material whose thermal conductivity is less than 0.10 W/m.degree. C. for example polystyrene foam into contact with a phenolic foam forming mixture and allowing the phenolic foam forming mixture to foam and set so as to form a layer of phenolic foam bonded to the layer of flexible insulating material.A second preformed layer of flexible insulating material whose thermal conductivity is also less than 0.10 W/m.degree. C. can be brought into contact with the phenolic foam forming mixture so as to form a sandwich structure with the layers of flexible insulating material bonded to opposite faces of the layer of phenolic foam. The effect of the layers of flexible insulating material is to decrease the variation in properties of the foam through its cross section.
摘要翻译：用于生产酚醛泡沫复合材料的连续方法包括将导热率小于0.10W / m℃的预制层的柔性绝缘材料（例如聚苯乙烯泡沫）与酚醛泡沫形成混合物接触并使酚醛泡沫形成混合物以发泡和固化，以形成结合到柔性绝缘材料层的酚醛泡沫层。热导率也小于0.10W / m℃的第二预制柔性绝缘材料层可以与酚醛泡沫形成混合物接触，以形成夹层结构，其中柔性绝缘材料层粘合到相对的酚醛泡沫层的面。柔性绝缘材料层的作用是通过其横截面减小泡沫的性能变化。
