Изобретение относитс к переработке пластмасс и может найти широкое применение при реализации различных способов изготовлени армированных изделий сложной формы, особенно из пластмасс, имеющих большую усадку, например из фторопласта-4.The invention relates to the processing of plastics and may find wide application in the implementation of various methods for the manufacture of reinforced products of complex shape, especially plastics having a large shrinkage, for example, from fluoroplastic-4.
Известен способ получени армированных изделий из пластмасс, заключающийс в том, что арматура вводитс на знаке в форму, заполн емую затем полимерным расплавом 1.A method of producing reinforced plastic products is known, which means that the reinforcement is introduced on a sign into a mold that is then filled with a polymer melt 1.
Однако этот способ переработки неизбежно приводит к по влению в отформированном изделии сложной формы больших остаточных напр жений, вызывающих его растрескивание из-за Ьадки материала.However, this method of processing inevitably leads to the appearance in the molded product of a complex form of large residual stresses causing its cracking due to the lump of material.
Наиболее близким к предлагаемому вл етс способ изготовлени армированных изделий из пластмасс, включающий нанесение на арматуру промежуточного сло и спрессовывание ее полимерным материалом 2.Closest to the present invention is a method of manufacturing reinforced plastic products, comprising applying an intermediate layer to the reinforcement and compressing it with a polymeric material 2.
Однако такой способ не обеспечивает требуемого качества получаемых изделий, так как имеет место растрескивание изделий, поскольку в услови х всестороннего схсати , реализуемого в форме, деформаци наружногоHowever, this method does not provide the required quality of the resulting products, since there is a cracking of the products, because under the conditions of a comprehensive fit that occurs in the form, the deformation of the outer
сло , выполненного из эластсмеров, например резины, весьма мала.A layer made of elastemer, such as rubber, is very small.
Цель изобретени - повышение качества изделий.The purpose of the invention is to improve the quality of products.
Поставленна цель достигаетс тем, что в способе изготовлени армированных изделий из пластмасс, включак цем нанесение на арматуру промежуточного сло и опрессовывание ее полимерto ным материалом, в качестве промежуточного сло используют легкоплавкий материал, причем толщина его равна величине усадки полимерного материала .The goal is achieved by the fact that in the method of manufacturing reinforced plastic products, including applying an intermediate layer to the reinforcement and pressing it with a polymeric material, a low-melting material is used as the intermediate layer, its thickness being equal to the shrinkage value of the polymeric material.

На чертеже изображена форма дл реализации предлагаемого способа.The drawing shows the form for the implementation of the proposed method.
В форму дл прессовани армированной втулки, состо щую из обоймы 1, опорного кольца 2 и пуансона 3, уста20 навливают знак 4, предназначенный дл фиксации арматуры 5 в изделии. Арматуру 5, например втулку, изготовл ют из латуни или другого металла и снабжают наружным, легкоплавким A symbol 4 is inserted into the mold for pressing the reinforced sleeve, consisting of the sleeve 1, the support ring 2 and the punch 3, to fix the reinforcement 5 in the product. The armature 5, for example the sleeve, is made of brass or other metal and is provided with an outer, low-melting
25 слоем 6.25 layer 6.
Наружный слой может быть выполнен из любого легкоплавкого материа;ia с температурой плавлени ниже температуры плавлени илц отверждени 30 перерабатываемой пластмассы, а егоThe outer layer can be made of any low-melting material; ia with a melting point below the melting point or solidification of the plastic being recycled, and its
