Process for the production of alkali metal silicate-organic plastics
| Details |
Inventors: Blount, David H.;
Assignee:
Primary Examiner: Foelak; Morton
Assistant Examiner:
Attorney, Agent or Firm:
Polymerable organic compounds are emulsified with aqueous alkali metal silicate solutions then polymerized with a catalyst such as a peroxide type catalyst thereby producing an alkali metal silicate organic plastic which may be used as an adhesive or as molding powder. |
|
DETAILED DESCRIPTION I claim: 1.
The process for the production of foamed polyurethane silicate product by mixing and reacting the following components: (a) an aqueous alkali metal silicate solution in the amount of 100 parts by weight; (b) a polymerizable unsaturated organic compound in the amount of 5 to 100 parts by weight; (c) a mono or polycarboxylic acid salt-forming compound in the amount of 1 to 10 parts by weight; (d) an initiator in a catalytic amount; (e) 50 to 200 parts by weight of a polyisocyanate, up to 10% by weight of a polyisocyanate initiator, up to 20% by weight of an emulsifier, up to 50% by weight of a blowing agent, up to 20% by weight of a regulator, and 1 to 150 parts by weight of a polyol are mixed with the emulsive mixture of Components (a), (b), (c) and (d), thereby producing a foamed polyurethane silicate product; percentages are based on weight of the Components (a), (b), (c) and (d).
2.
The product produced by the process of claim 1.
3.
The process for the production of foamed polyurethane silicate products by mixing and reacting the following components: (a) an aqueous alkali metal silicate solution in the amount of 100 parts by weight; (b) a polymerizable unsaturated organic compound in the amount of 5 to 100 parts by weight; (c) a mono or polycarboxylic acid salt-forming compound in the amount of 1 to 10 parts by weight and consisting of organic acid; (d) an initiator in a catalytic amount; then Components (a), (b), (c) and (d) are mixed and reacted, thereby producing an alkali metal silicate-organic plastic emulsion, then (e) 50 to 200 parts by weight of an organic polyisocyanate, up to 10% by weight of a polyisocyanate initiator, up to 20% by weight of an emulsifier, up to 50% by weight of a blowing agent and 1 to 150 parts by weight of a polyol are added to and mixed with the alkali metal silicate-organic plastic emulsion and allowed to react, thereby producing a foamed polyurethane silicate product; percentages are based on the weight of Components (a), (b), (c) and (d)
