Abstract
The invention relates to the technical field of phenol formaldehyde foam waste secondary utilization, in particular a secondary utilization method for phenol formaldehyde foam waste; the following components in part by weight are used in the process of treating the phenol formaldehyde foam waste: 100 parts of phenolic resin, 5 to10 parts of phenol formaldehyde foam powder, 5 to 10 parts of polymer, 2 to 3 parts of surfactant, 8 to 10 parts of curing agent, 10 to 15 parts of aluminium hydroxide and 10 to 20 parts of foaming agent; the treatment steps are as follows: A, crashing the waste phenol formaldehyde foam into fine powder of 200 meshes for the future use; B, adding the foam waste powder, the polymer, the surfactant and the aluminium hydroxide in sequence, uniformly agitating the materials for the future use; C, adding the foaming agent for uniformly agitating the materials before foaming; D, infiltrating the prepared materials and curing agent according to the capacity requirements of foam product to a mixer head for high-speed mixing, and then putting the mixture to a mould for foaming to acquire the product; the synthesis process of the method is simple, so that the phenol formaldehyde foam is recycled, thus the purposes of reducing the cost and reducing the pollution are achieved.
Description
Technical field
The present invention relates to the technical field of phenol formaldehyde foam waste material second stage employ, particularly a kind of second stage employ method of phenol formaldehyde foam waste material.
Background technology
Phenol formaldehyde foam has excellent insulating performance and uninflammability ability as lagging material, but its outstanding shortcoming is his fragility, in construction, is easy to fragmentation, produces a large amount of depleted foams, can not use, and not only use cost rises, and contaminate environment.The present invention is exactly a kind of utilization that proposes to the waste that produces in imperfections that produces in this production and the construction process, to reach the foamy recycle, reduces cost, and reduces and pollutes.
Summary of the invention
The object of the present invention is to provide a kind of second stage employ method of phenol formaldehyde foam waste material, mainly solve above-mentioned existing in prior technology defective, the synthesis technique of the inventive method is simple, to reach the recycle of phenol formaldehyde foam, reduces cost, and reduces the purpose of polluting.
For realizing above-mentioned purpose, the present invention realizes like this.
A kind of second stage employ method of phenol formaldehyde foam waste material; It is characterized in that: this method employed each substance weight umber in handling phenol formaldehyde foam waste material process is 100 parts in a resol, 5 ~ 10 parts of phenol formaldehyde foam waste material powders, 5 ~ 10 parts in polymkeric substance; 2 ~ 3 parts in tensio-active agent; 8 ~ 10 parts in solidifying agent, 10 ~ 15 parts in white lake, 10 ~ 20 parts of whipping agents; Treatment step is A, it is for use that the depleted phenol formaldehyde foam is ground into 200 purpose fine powders; B, add foam waste powder, polymkeric substance, tensio-active agent, white lake successively and stir for use; C, before foaming, add whipping agent and stir; D, by the inlet amount of the volume requirement of foam finished product the above-mentioned material for preparing and solidifying agent are squeezed into the mixing machine head and are carried out mixed at high speed after, get into the mould foaming, get product.
Described method is characterized in that: each substance weight umber is 50 ~ 60 parts of acrylic amides in the described polymer composition, 5 ~ 10 parts of sodium allylsulfonates; 5 ~ 10 parts of Propylene glycol monoacrylates, 2 ~ 5 parts of vinylbenzene, 10 ~ 15 parts of Sodium Persulfates; 6 ~ 8 parts in phosphorous acid, 100 parts of zero(ppm) water.
Described method is characterized in that: described tensio-active agent is a Tween-80.
Described method is characterized in that: described solidifying agent is 50% sulfuric acid.
Described method is characterized in that: described whipping agent is dichloro one fluoroethane.
The advantage that prescription of the present invention and method can embody is:
1, phenolic foam biggest drawback is his brittle, easily broken in the construction, resulting in a large number of abandoned foam can not be used, not only to use rising costs and environmental pollution.The present invention is exactly a kind of utilization that proposes to the waste that produces in imperfections that produces in this production and the construction process, to reach the foamy recycle, reduces cost, and reduces and pollutes.
If 2 direct powders with phenol formaldehyde foam add to go in the resol to foam again, will make the strength degradation of material over half, the present invention is when adding the foam powder; Added a kind of polymkeric substance; It is a kind of synthetic waterborne polymeric, and the adding of this polymkeric substance can make foam process normally carry out; Also do not reduce the intensity of material, have excellent popularization and be worth.
Embodiment
Embodiment 1:A, that 10 parts of depleted phenol formaldehyde foams are ground into 200 purpose fine powders is for use.B, add foam waste powder, 8 parts in polymkeric substance, 3 parts in tensio-active agent, white lake successively and stir for use for 13 parts.C, before foaming, add whipping agent and stir for 15 parts.D, by the inlet amount of the volume requirement of foam finished product the above-mentioned material for preparing and solidifying agent are squeezed into the mixing machine head and are carried out mixed at high speed after, get into the mould foaming, get product.
Embodiment 2:A, that 5 parts of depleted phenol formaldehyde foams are ground into 200 purpose fine powders is for use.B, add foam waste powder, 5 parts in polymkeric substance, 2 parts in tensio-active agent, white lake successively and stir for use for 10 parts.C, before foaming, add whipping agent and stir for 10 parts.D, by the inlet amount of the volume requirement of foam finished product the above-mentioned material for preparing and solidifying agent are squeezed into the mixing machine head and are carried out mixed at high speed after, get into the mould foaming, get product.
