Abstract
Abstract A method for preparing polymerized products by spraying unsaturated polyester resin syrup, aqueous sodium silicate and a polymerization initiator for the unsaturated polyester resin syrup. The ingredients preferably are formed into sprays which are mixed by impingement. Alternatively the ingredients may be combined into a single spray. These sprays may include inert fillers in spray form. Preferably the sprays are impinged upon inert fillers including chopped fibrous reinforcements such as glass fibers.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
104 words
The method of preparing a cured thermoset article which comprises A. spraying an alkaline mixture onto a substrate as a continuous mass, said alkaline mixture comprising: 1. component 1 comprising one part by weight of an unsaturated polyester resin syrup; and 2. component 2 comprising 0.1 to 10 parts by weight of aqueous sodium silicate containing 45 to 85 weight percent water and 55 to 15 weight percent sodium silicate solids having a weight ratio of SiO 2 /Na 2 O of 1.5 to 3.75; the said alkaline mixture including a polymerization initiator for unsaturated polyester resin syrup; and B. curing the said mass.
Claim 2
Independent Claim
104 words
The method of preparing a cured thermoset article which comprises A. spraying an alkaline mixture onto a substrate as a continuous mass, said alkaline mixture comprising: 1. component 1 comprising one part by weight of an unsaturated polyester resin syrup; and 2. component 2 comprising 0.1 to 10 parts by weight of aqueous sodium silicate containing 45 to 85 weight percent water and 55 to 15 weight percent sodium silicate solids having a weight ratio of SiO 2 /Na 2 O of 1.5 to 3.75; the said alkaline mixture including a polymerization initiator for unsaturated polyester resin syrup; and B. curing the said mass.
Claim 3
Dependent Claim
16 words
The method of claim 1 wherein the said polymerization initiator is an ingredient of component 1.
Claim 4
Dependent Claim
16 words
The method of claim 1 wherein the said polymerization initiator is an ingredient of component 2.
Claim 5
Dependent Claim
36 words
The method of claim 1 wherein component 1 is provided as an airborne spray and component 2 is provided as an airborne spray; and the two said sprays are impinged to produce the said alkaline mixture.
Claim 6
Dependent Claim
28 words
The method of claim 4 wherein the two said sprays impinge upon a stream of chopped glass fibers to produce glass fibers coated with the said alkaline mixture.
Claim 7
Dependent Claim
28 words
The method of claim 1 wherein the said component 1 and component 2 are formed into the said alkaline mixture which is then formed into a single spray.
Claim 8
Dependent Claim
25 words
The method of claim 6 wherein the said single spray is directed into a stream of chopped glass fibers prior to contacting the said substrate.
Claim 9
Dependent Claim
14 words
The method of claim 1 wherein the said alkaline mixture includes inert particulate fillers.
Claim 10
Dependent Claim
31 words
The method of claim 8 wherein the said inert particulate fillers are direcrted as a separate stream into the said alkaline mixture when the said alkaline mixture exists as a spray.
Claim 11
Dependent Claim
57 words
The method of claim 1 which comprises sequential steps including: First: spraying the said alkaline mixture onto the said substrate as a deposited coating; Second: applying fibrous reinforcement to the said deposited coating; Third: spraying the said alkaline mixture onto the applied fibrous reinforcement; Fourth: curing the said alkaline mixture; Fifth: recovering a laminated fiber-reinforced, thermoset article.

Dependent Claim
10 words
SECOND: depositing a metal screen onto the said deposited coating;
Claim 17
Dependent Claim
13 words
THIRD: spraying additional akaline mixture of claim 1 onto the said metal screen;
Claim 18
Dependent Claim
6 words
FOURTH: curing the said alkaline mixture;
Claim 19
Dependent Claim
6 words
FOURTH: curing the said alkaline mixture;
Claim 20
Dependent Claim
7 words
FIFTH: recovering a metal-reinforced, thermoset laminated article.
Claim 21
Dependent Claim
7 words
FIFTH: recovering a metal-reinforced, thermoset laminated article.
