Abstract
The phenolic coated shuttering for building construction is made up through such technological steps as proportioning phenolic resin, defilming agent and moistener, mixing, applying directly on single or double surfaces of plywood, drying in air or not, hot pressing, trimming edge and enclosing, and features low cost.
Description
The invention provides a kind of phenolics-covered shuttering and processing method thereof, belong to the construction formwork manufacture technology field.
In building operations, use veneer very general at present as template.But make template with veneer many shortcomings are also arranged: (1) timber easily absorbs water, easy layering when plywood form is used, and cause recycling rate of waterused not high: (2) face veneer is crude, and is not wear-resisting, easily adheres to cement, demoulding difficulty etc.For overcoming above-mentioned defective, produced a kind of resin impregnating paper face plywood abroad, be commonly called as film plate.This film plate is the specialties heavy high with absorption, that wet strength is high, by the soak drying machine impregnated phenolic resin, it is attached on the veneer be made again.Yet China does not still have the producer that produces resin impregnating paper at present, entirely by external import.Even the import of domestic minority producer resin impregnating paper, yet need to introduce technology in addition and equipment, the resin impregnating letterweight could be attached on the veneer, produce film plate.Thereby the cost of domestic production film plate is very high.
The purpose of this invention is to provide and a kind ofly need not overlay resin impregnating paper and properties of product phenolics-covered shuttering and the processing method thereof identical with film plate.
The present invention seeks to realize like this: phenolics-covered shuttering, comprise 7-11 layers normal plywood by phenolic resin adhesion, it is characterized in that the two-sided or single face of normal plywood scribbles the common phenolic resins of one deck.The processing method of this phenolics-covered shuttering reaches technological parameter according to the following procedure and carries out: common phenolic resins, be equipped with the auxiliary agent such as remover, wetting agent, plasticizing agent of common ratio, and stir, coat the two-sided or single face of veneer, coating weight is 100-300g/m
2, (or not airing) sends into hot pressing in the hot press that suitable backing plate is housed and scribbles remover, hot pressing time 5-20 minutes, 100-180 ℃ of hot pressing temperatures, hot pressing pressure 5-20kg/cm behind the airing
2, after the hot pressing, through clear limit, edge sealing phenolics-covered shuttering.
The processing method of this product is simple, but products obtained therefrom is identical with film plate on performance.Overcome and made film plate and at first want import resin impregnating paper and need Introducing Technical Equipment and invest the high weak point of big cost.Gained phenolics-covered shuttering of the present invention, smooth surface, hard, wear-resisting, acid and alkali-resistance, water-fast soaking, repeat usage height.
Claims (2)
1. the phenolics-covered shuttering that building operations is used comprises by 7-11 layers normal plywood of phenolic resin adhesion, it is characterized in that: the two-sided or single face of normal plywood scribbles the common phenolic resins of one deck.
2. the processing method of the phenolics-covered shuttering used of a building operations, it is characterized in that this processing method reaches technological parameter according to the following procedure and carries out: common phenolic resins, be equipped with the auxiliary agent such as remover, wetting agent, plasticizing agent of common ratio, stir, coat the two-sided or single face of veneer, coating weight is 100-300g/m
2, behind the airing (or not airing) send into hot pressing in the hot press that suitable backing plate is housed and scribbles remover, hot pressing time 5-20 minutes, 100-180 ℃ of hot pressing temperatures, hot pressing pressure 5-20kg/cm
2, after the hot pressing, through clear limit, edge sealing phenolics-covered shuttering.
