Detailed description of the invention
For the technological means making the present invention realize, creation characteristic, reaching purpose and act on more clear and be apparent to, the present invention is further elaborated with detailed description of the invention below in conjunction with the accompanying drawings:
With reference to Fig. 2 and combine Fig. 3, the present invention proposes the production technology of a kind of porcelain tendre polyurethane thermal insulation and decoration composite plate, including:
S100, substrate are processed: take 3～10cm thick polyurethane thermal insulation boards as substrate, and process a groove in a wherein plate face of substrate, working depth h of described groove is 1～1.5cm, and each sidewall distance substrate edges a=0.5～1cm[is here, the processing mode of groove has a variety of, such as utilize easy mould just can process producing polyurethane thermal insulation board when, say for another example and can also process by the way of machine cuts in type polyurethane thermal insulation board；Working depth for groove tentatively determines the thickness proportion between porcelain tendre layer and heat-insulation layer]；
S200, porcelain tendre stir: take the porcelain tendre raw material of 100～150 weight portions, and the water being added thereto to 20～30 weight portions carries out mix and blend, until making porcelain tendre raw material become viscous pasty state, mixing time controls 10～15min, standby [here, by controlling porcelain tendre raw material and the part by weight that adds water, the porcelain tendre layer that the later stage formed can be made to have preferable flexibility, and then obtain the composite plate of cracking resistance excellence；Stirring action is unsuitable too short simultaneously, also unsuitable long, the two state presented in whipping process in Binding experiment, it is optimal for mixing time being controlled 10～15min, both porcelain tendre raw material can have been made sufficiently to be dissolved and mix, and the state after porcelain tendre raw material can be made again to stir is just right to following process]；
S300, mortar are smeared: the adhesive mortar of existing mixing on the groove uniform floor uniform application of substrate, the amount ranges of described adhesive mortar is 4～5kg/m2[here, for adhesive mortar, the present invention can preferentially choose polymer bonding mortar, and it is to be formed by Binder Materials and the organic polymer stirring that can be dispersed in water]；
S400, porcelain tendre inject: before adhesive mortar setting and hardening, porcelain tendre raw material stirring completed is injected in the groove of substrate until being filled and led up by groove, and scrape off and exceed the part porcelain tendre raw material of substrate surface [here, owing to porcelain tendre raw material is in viscous pasty state, when being injected in groove, can be pressed tightly against on adhesive mortar, and whole groove can be tamped]；
nullS500、Porcelain tendre solidifies: dried by the drying line that the substrate feeding being injected with porcelain tendre raw material is disposed with electric heater unit and hot-air drying unit，Porcelain tendre raw material is made to be solidified in substrate，Described drying line is first electrically heated drying to the substrate being injected with porcelain tendre raw material，Dry temperature to control at 90～100 DEG C，Drying time is arranged on 45～50min，Then the substrate being injected with porcelain tendre raw material is carried out hot-air seasoning，Dry temperature to control at 40～55 DEG C，Drying time is arranged on 20～30min，Drying line also makes it be re-fed into hot-air drying unit [here after cooling down 7～8min under field conditions (factors) after electrical heating is dried completing its (" its " refer to be aforesaid " being injected with the substrate of porcelain tendre raw material ")，Porcelain tendre solidification belongs to the step that preparation method of the present invention is the most key，It is the basis determining composite plate quality]；
S600, blowing maintenance: the complex completing to dry is blown maintenance 2～3 days, prepare porcelain tendre polyurethane thermal insulation and decoration composite plate [here, blowing maintenance is for natural conditions maintenance, the composite plate after drying can not only be made quickly to cool down, and the production time can be shortened, improve production efficiency].
In above-mentioned porcelain tendre curing schedule, the present invention is first electrically heated drying (strongly) to complex, then hot-air seasoning (gentle) is carried out, and between also by cooling transition naturally, the substrate being injected with porcelain tendre raw material is i.e. allowed successively to have passed through the process of high temperature-cooling-insulation, both ensure that successful curing on polyurethane substrate of porcelain tendre raw material by such a temperature environment, and turn avoid polyurethane thermal insulation board and can change and then cause composite plate to prepare unsuccessfully in drying course.
